Modern European Philosophy: Structuralism & Poststructuralism

With Hegel, we talked about reality as a social construct.  While Hegel believed that reason could build the objective system as sum of subjective positions, more skeptical thinkers such as Kierkegaard, Nietzsche, Heidegger, Sartre, Wittgenstein, as well as Feyerabend and Latour argue that our constructed systems are open and evolving.  Today, we will look at Structuralism and Poststructuralism, examining thinkers who are concerned with how and why we construct our reality the way that we do.  Next time, we will conclude with covering Postmodernism, a close relative of Poststructuralism.

Structuralism is a movement and method that focuses on social constructs, language games and forms of life, much like late Wittgenstein.  Cultures, such as science and philosophy, are sets of people and things, but more than this they are networks, systems of relationships.  Hegel argues that we compose our thinking very much in terms of Self and Other, an idea Sartre develops in criticism of nationalism and racism.  Structuralism sought to understand the life of cultures as a construction of language and system of relationships, influenced by Phenomenology and reacting against Existentialism.  Like the Phenomenologists, Structuralists tried to give a scientific account of the human experience.  Unlike the Existentialists, Structuralists seek the set and stable order that underlies all cultures.  While Existentialism emphasizes the free individual creation of meaning, Structuralism emphasizes the social determination of meaning, such that the individual is largely, if not entirely, determined by the structure in which they participate.  In France, Sartre and Levi-Strauss’ disagreement over human freedom became symbolic of the fight between Existentialism and Structuralism.

Two of Popper’s favorite thinkers to hate, Karl Marx (1818 - 1883) and Sigmund Freud (1856 - 1939) had a profound impact on Structuralism.  Marxism and Psychoanalysis, which unlike Popper still consider themselves to be sciences, argue that individual life is largely determined by underlying systems, for Marx the economy and modes of production, for Freud the unconscious mind and core drives.  Both Marx and Freud argue, like Structuralists, that individuals are largely unaware of the systems by which their actions are determined, like Spinoza argued, believing they are free in their behavior when in fact their behavior and its meaning has largely been predetermined.

We will not extensively cover Marxism or Psychoanalysis in this class, nor delve into the work of Marx or Freud, as each alone could span several class periods, but we will consider Marxist and Psychoanalytic concepts that are relevant to Structuralism.  Marx, who took Hegel’s system and turned it upside-down, argued that history is the process of class conflict, of the dialectic between the rich owners and the poor laborers.  Society is largely concerned with protecting the property of the owners and maintaining it through control of the laborers by the middle class.  Freud, who marveled at the similarities between his own work and the work of Schopenhauer, argued that behavior is the process of subconscious conflict, of the dialectic between satisfaction and repression.  The Ego or Self is the result of the conflict between the Id, which seeks gratification, and the Superego, which seeks to put the Id in check and delay gratification.  Notice that both Marx and Freud see a basic opposition painfully and tentatively resolved by a mediating central component, for Marx the middle class who go to college and then work in various careers, for Freud the Ego that forms individual identity by various tactics of compromise.  Like Fichte’s Ich, Freud’s Ego is a negotiation of self-assertion and self-denial, much like Schelling and Hegel’s syntheses as compromise of affirmation and negation.

The third theorist who served as the basis of Structuralism is Ferdinand de Saussure (1857 - 1913), the Swiss linguist whose work on Semiology, the study of meaning, became very important for later European thought.  His lectures between 1907 and 1911 were later published as A Course in General Linguistics.  Saussure argued that words stand for concepts, which are sets of things, “apple” standing equally for each thing we gather into our conception of apples.  Saussure argued that words are sets of sounds that are defined in terms of difference.  ‘Cat’ and ‘hat’ are very similar words, only one of three sounds being different, but cats and hats are very different.  We could far more easily confuse the words ‘cat’ and ‘hat’ than we could a cat for a hat (although, as Oliver Sacks well knows, sometimes a man can confuse his wife for a hat).

For Saussure, a sign, like the roadsign of Wittgenstein and the turn-signal of Heidegger, is both a signifier, the sound, image or media as physical component, and a signified, the idea or concept as mental component.  Notice that just as Hegel and others argue that the objective is the subjective and the mind is the world, both the physical and mental components are inseparable in the sign.  If they are separated, and one or the other isn’t present, we can say that it no longer is the same sign with the same meaning.  A road sign on someone’s bedroom wall no longer means what it used to, though if we put it back in its place again it would.

Saussure’s major principle is the Arbitrariness of the Sign.  Just as we would have little trouble distinguishing a cat from a hat but more trouble with the words, for the most part words have no resemblance to the things they represent.  The word ‘cat’ is nothing like a cat in shape or sound.  Because of this, words that resemble each other can represent things that have little to do with each other, just as things that resemble each other can be represented by words that have little to do with each other, such as ‘cat’ and ‘tiger’.  Also, because words can change in a language, as well as things can change in an environment, there is no fully fixed signification.  There is no fixture of the system even though the system is the fixture, like the Pragmatists argue such as Peirce, who along with Saussure is considered one of the founders of Semiology.

There are exceptions of signs that are not arbitrary, which Saussure calls ‘motivated’.  Onomatopoeia, words that imitate sounds, are motivated, such as ‘meow’, ‘zip’, and thus ‘zipper’.  In English, there are few or no words (I cannot think of any) that look like what they represent, as English and many other languages are derived via Roman Latin from the Phoenician alphabet.  While scholars accept that the letters of the Phoenician alphabet are derived from picturing individual things, they are in debate over what things inspired which letters, as the alphabet evolved to the point that many of the original correspondences are long lost.  Some scholars agree that ‘A’ likely came from the head of a cow or ox, and ‘B’ likely came from a house, both significant to early civilization.  Notice that an upside-down ‘A’ resembles a horned animal, and a ‘B’ on its side resembles a building with a flat roof and a doorway in the middle.  Similarly, in Chinese entire words can resemble the things they represent, but like the Phoenician based alphabet ancient Chinese has evolved so thoroughly that there is often little resemblance that can be recognized easily.  All of this seems to confirm Saussure’s principle of arbitrariness.

Another type of exception of signs that are not arbitrary are portmanteau, words that are composed of multiple words.  While ‘cat’ and ‘nap’ don’t look or sound like cats or naps, a ‘catnap’ does resemble the short naps taken by cats.  The word ‘portmanteau’ was itself coined by Lewis Carroll in his book Alice in Wonderland, a text I cover in the Introduction to Philosophy and Logic classes in terms of late Wittgenstein, who in a footnote of the Philosophical Investigations writes cryptically, ““Compare to a remark of Lewis Carroll’s”, which seems to refer to the poem Jabberwocky.  It is near this poem of Carroll’s, as Humpty Dumpty explains to Alice how to read the poem, that Carroll has Humpty Dumpty say, “It’s like a portmanteau”.  In French, ‘porter’-’manteau’ means ‘carry’-’cloak’, and the French conjunction had already in Carroll’s day been borrowed in English to refer to another portmanteau, the suitcase.

Regardless of these exceptions, Saussure argued that the mind generates systems by association and disassociation of similar and dissimilar things.  In this way, we create systems of signs that direct the ordering of society.  There is little room for individual creativity, however.  Consider that there is little room on the street for creative use of turn-signals.  In an art gallery, there is more room for creative reappropriation, and with the Dada movement this became a staple of modern art.

The father of Structuralism, however, was not Saussure but the French Anthropologist, Claude Levi-Strauss (1908 - 2009), not to be confused with the inventor of blue jeans who shares the same hyphenated last name.  Levi-Strauss said that his three loves were Geology, Marx and Freud.  All three seek the hidden layers below that determine the formations above.  In 1934 Levi-Strauss and his wife became professors in Sao Paulo, Brazil, and he would often venture into the jungle to meet Amazonian tribespeople, finding their cultures to be more elaborate and complex than he had expected.  After the end of WWII, he returned to Paris where he merged the work of Kant, Hegel, Marx, Freud and Saussure into a new Philosophy of Anthropology he called Structuralism, the search for the universal underlying patterns of human behavior.

Like William James, Levi-Strauss was very much a functionalist, who argued that primitive and modern people share the same mind and behaviors, and that all human behavior is rooted in some utilitarian value.  James is considered one of the founders of Psychology just as Levi-Strauss is considered one of the founders of Anthropology.  Both are similar to Feyerabend and Latour in their denial of exclusive differences between ancient cultures and modern cultures.  However, unlike James, Levi-Strauss argued that there are some behaviors which have a merely symbolic and not material value, the benefits being mental rather than physical.  For Freud, the symbolic, like fantasy, is a strategy of the ego for releasing repressed drives, reenacting the repressed by other means, acting in a way that one wishes to act but cannot.  This is similar to Nietzsche, who argued that philosophy is a personal confession of the author.

Levi-Strauss argued that human beings do not establish absolutes, but form relationships.  For example, while a parent might not be perfect or always right, they are in a relationship with a child such that they are in the position of authority.  Levi-Strauss’ work was focused on examining the relationships of relationships.  A family or culture is a relationship of relationships.  While earlier anthropologists argued that identity is a matter of linear descent from a single patriarch, Levi-Strauss argued that identity is a matter of the relationship between families that intermarry, a relationship between two sets of relationships.

Levi-Strauss sought to understand the universal patterns underlying the similarities and differences of sets of relationships.  For example, what impact or connection does the relationship of father and son have on mother and daughter, or the relationship of mother and father have on daughter and father or daughter and son?  Levi-Strauss noted that these always varied by culture, finding numerous variations between the Brazilian tribes he studied, but he argued that these variations must have an underlying pattern, such that a more relaxed relationship between mother and father might correspond to a more disciplinary relationship between mother and son.  While much of these correlations have been called into question by both the psychoanalytic and non-psychoanalytic communities, Levi-Strauss’ work stimulated further investigations that were foundational for many anthropologists.

The title of Levi-Strauss’ most famous book, La Pensee Sauvage (1962), is often translated as “The Savage Mind”, but because, like Feyerabend and Latour, Levi-Strauss argues that there is no savage mind or primitive thinking, it’s title is better translated as “Thinking in the Raw”, or “Raw Thinking”.  While many think of primitive people as children who have undeveloped minds, Levi-Strauss argues that primitive tribespeople are quite capable of sophisticated systematization, and that modern people are quite capable of foolish fetishes and totemism.  Like Moderns, as Latour would say, tribespeople use logic to classify plants and animals in sophisticated systems and put these systems into evolving practice.  Modern corporations have found these “primitive” practices to be quite valuable.  In the Logic class, we study the anthropologist Malinowski’s argument that primitive tribespeople have all of the operations of modern Logic in their languages, and put them into practice with success.

Levi-Strauss borrowed Saussure’s conception of the sign, Freud’s conception of the symbolic, and Marcel Mauss’ theory that primitive culture, like modern culture, is founded on gift giving, which is not only practical but symbolic.  Consider the modern act of marriage being established in a husband giving an expensive diamond ring to his wife, practical as she carries thousands of dollars with her on her hand and symbolic as she is expected to be faithful and is trusted with this wealth.  Note that the symbolic is not impractical, but an extension of the immediately practical.  Levi-Strauss extended Mauss’ theory to the exchange of words, as well as women in primitive and modern cultures.  The patriarchal nature of the diamond ring example here is appropriate.  Levi-Strauss later replied to feminist critics who saw this as sexist that matriarchal tribes have similarly exchanged men but that patriarchal exchange of women was unquestionably predominant.  It is also possible to imagine women and men equally exchanged by varying tribes.  The daughters and sons of the wealthy and powerful are still encouraged to intermarry today.

In his book Totemism (1962), Levi-Strauss argued that totemism, like that of primitive tribespeople who identify with a particular animal as spiritual kin, is very human, as the human mind is metaphoric by nature.  We have seen this same idea before with Merleau-Ponty, Lakoff and Rorty.  An individual or tribe may value strength or speed, and so relate to similar abilities in the bear or wolf.  Totems, as central cultural metaphors, are aids to the social process of thought.  Just as the word ‘wolf’ serves as a handle for the concept of wolves, the word can be used metaphorically to extend to things that are not wolves, such as a rogue pack of financial advisors.  Consider the trickster animals of Native American mythology, such as coyote or crow, who bring the world into existence in spite of their deceptive and playful nature.

Levi-Strauss analyzed mythology in terms of such metaphors in his massive four-volume work, Mythologiques (1964 - 1972).  Myths show us metaphors that are symbolic extensions of reality.  This is beneficial but also problematic, as it is still today according to Rorty.  Metaphors can be used to establish patterns and themes via narratives, what Levi-Strauss called “mythemes”, and this communication of meaning can serve to solidify dogmatic understandings or support skeptical inquiries.  Consider the lion as the animal symbolic of both British empire and Buddhist wisdom.  Levi-Strauss, like Freud, argued that myths are often used by cultures to overcome or understand contradictions, a symbolic act which may be conscious or unconscious.

In the ancient Greek myth of Oedipus, a famous psychoanalytic favorite, Oedipus unknowingly kills his father and marries his mother, and this expresses the contradiction of hating and loving one’s family, friends, culture, and humanity.  In the ancient Greek myth of Antigone, Oedipus’ daughter, Antigone’s brothers fight for the throne, one slays the other, and Antigone chooses to bury her brother rather than obey the law, and this expresses the contradiction of obeying the universal law and loyalty to the familiar.  As Nietzsche argued, this is displayed as a tragedy, as a rational strategy for putting what cannot be resolved by reason on display.  Levi-Strauss attempted to systematize the similarities of world mythology using these as central examples.  We construct mythology as messages to those who will understand in the future, to those who will face similar problems and contradictions.

Reacting against the open Existentialism of Sartre and his circle, Levi-Strauss was joined by Lacan, Foucault and Barthes as Structuralism rose to prominence in French thought.  This was immortalized in a 1966 cartoon, The Structuralists’ Lunch Party, which showed the four philosophers sitting on the ground wearing grass skirts.  The Structuralists, like the Existentialists, were pessimistic about modern society, but rather than endorse free individual transformation, they chose to critically seek the patterns of systems in pre-modern people.  We will consider each of these, starting with Lacan.  As we turn to Barthes and then Foucault, we will be passing from Structuralism to Poststructuralism.  While Poststructuralism continued to be influenced by Levi-Strauss’ critical examination of systems, it gave up on revealing universal underlying patterns.

Jacques Lacan (1901 - 1981) was mentioned already with Hegel, Heidegger and Bataille.  He even married Bataille’s estranged wife.  Lacan studied Nietzsche, Hegel, Heidegger and Jaspers while studying medicine.  I mentioned that Lacan attended Kojeve’s lectures on Hegel with Bataille and that he tried to systematize Nietzsche using Freud.  Lacan became a psychiatrist in the 1920s, while he was involved with the Surrealists in Paris.  His thesis, Paranoid Psychosis and its Relations to the Personality, was an influence on many Surrealists, such as Dali and Breton, both friends of Lacan.  He was also a contributor to Surrealist journals and Picasso’s personal physician.

Lacan is most famous for his theory of the mirror stage and self-image, that we form a stable image and conception of ourselves by looking at others and our own reflection, then cling to it in the attempt to resolve the flux and contradictions of our thoughts and feelings, and then repress or redirect whatever does not conform to this image.  Much of Continental thought has been influenced by Freud and psychoanalysis, and Lacan became the central interpreter of Freud for French thought and those influenced by and involved with French thought, such as the Slovenian philosopher Zizek, already mentioned several times.

Lacan’s work centers on narcissism, not merely self-love, as it is often described, but self-obsession.  Both the body and the mind are composed of many parts which cooperate.  After the young child forms an image of self and begins to cling to it, the child forms narcissistic complexes, forms of excluding self from other that attempt to establish stability in an inevitably insecure situation.  The ego is always an “inauthentic agency”, concealing its own unstable lack of unity.  Note the Heidegger speak, and how we are always inauthentic no matter how relatively authentic we become.  Freud had wondered why narcissism develops early in children but is not present from the beginning, and Lacan believed he had solved this problem with his mirror stage and the formation of self image.  I mentioned with James that Freud believed religion was an attempt to regain the oceanic existence of infancy.  Recall that Nietzsche said that maturity is regaining the seriousness of a child at play.

Narcissism fragments the world.  The fear of self-disunity becomes anxiety, and anxiety becomes paranoia.  Disunity and contradiction are projected onto the world and others, away from the self and social selves in which the self participates and with which the self identifies.  Just as in metaphor, where one term is substituted for another, the other is substituted for the self.  The contradictions of the self becomes the contradictions of the other.  The self establishes its place relative to others.  This placement of the self becomes the Real to the self, much involved with the They of Heidegger.  Language is the primary tool by which the self alienates and articulates to fashion the Real.  This Real is, of course, not the entirety of reality, much as the thought is not all of experience for Heidegger.  The Real is merely a preferred image which is insecure, just like the self-image situated in the Real.  Lacan believed that making this transparent to the self is therapeutic, dissolving paranoid narcissistic delusions and obsessions that entrap the static images of self, other and Real.

Roland Barthes (1915 - 1980) balanced both Existentialism and Structuralism even as he was one of the four great French Structuralists, in spite of the feud between Sartre and Levi-Strauss.  Barthes, who was mostly concerned with the critical analysis of literature, is famous for his pronouncement of “the death of the author”, which is also “the birth of the reader”.  Just as Nietzsche argued that life, self and meaning are an open matter of interpretation, Barthes argued that texts can be read in any variety of ways, without fixture of its meaning by the author, the text’s authority.  As we read a text, we are not only connecting it to our personal life experience and within our cultural and ideological frame, but we are also critical of the author, reinterpreting their work in light of what we glean about them from the text.

Like Foucault, Barthes was a critic of the idea of the natural.  Barthes saw in his own day older religious pronouncements about what is “natural” and thus objectively true being replaced by political and scientific claims about the “natural”, as well as countercultural calls to return to the “natural”.  Barthes argued that there are no set facts, no objective truth, no natural pure states, but networks of signification that can be revealed as historical processes and cultural practices.  Barthes was loyal to Saussure and his notion of the sign as signifier and signified, and he examined “texts” such as advertisements for clothes and food products, noting that certain fashions were meant to signify luxury, happiness or freedom and certain food products meant to signify health, decadence or satisfaction.

Barthes’ book Mythologies (1957), widely considered to be his best work, is a short set of critical essays focusing on modern day production of mythology and meaning.  In the first essay, The World of Wrestling, Barthes argues that wrestlers, not athletes but the entertainers seen on American television derived from Mexican luchadores, are personifications of good and evil and wrestling is a “spectacle of excess”.  Barthes is not attacking wrestling, but examining it as a human expression of meaning, a modernday self-conscious mythologizing.  The signs and signification are clear, even exaggerated.  Barthes writes, “What the public wants is the image of passion, not passion itself”.  The crowd wants purified, mythologized justice, and they would rather watch a wrestling match or a detective show than an actual court trial.  The symbolic crime and punishment satisfies the displaced need for justice that is not purely obtainable in society, in line with Freud and Levi-Strauss.  Barthes notes that, in American wrestling, the bad guy is often associated with Communism.  When I was young, many of the villains in wrestling were associated with Islam.

In my favorite essay, Operation Margarine, which I discuss in the Ethics class when covering lies and propaganda, Barthes compares a margarine commercial to propaganda for the French military and colonialism.  Very much like a wrestling match, in which the bad guy cheats and seems victorious, only to be bested by the good guy, successful propaganda often puts criticized faults on display, and then has the faulty triumphantly rise over its faults.  The Established Order (Barthes’ capitalization) admits to being flawed, but argues that only it can save us all from these flaws.  Barthes is critical of American movies in which the main character, a likable guy with whom the viewer can identify, joins the army or police, rebels against its conformity, but then, against a greater evil, leads it to victory in the name of good.  Only the army can protect us from destruction and war, thus the need for slight confession followed by grand redemption.  Barthes compares this to a margarine commercial, in which one housewife is appalled that another has made a mousse not with butter but with margarine, a new product at the time which was trying to gain household acceptance.  The second housewife replies, “Here, try it!”, and the first says, “Wow, that is good!”, clearly rid of her old irrational prejudice, wealthier and wiser for using a cheaper product.  This is similar to scientists who reacted against critics of science, arguing that if people were more aware and informed about the sciences they would not be critical.

In the final essay, Myth Today, Barthes lays out his theory of modern mythology after summarizing the semiology of Saussure  For Barthes, much of meaning that is circulated in modern times is ideology which can serve as a mask for social contradictions, much as Rousseau wrote that polite society is a mask that conceals brutality and oppression.  As a left leaning intellectual, Barthes was particularly concerned with nationalist messages of peace, freedom and equality that conceal class and colonial domination.  The famous example of this is Barthes’ scornful analysis of the cover of an issue of Paris Match, the French equivalent of Newsweek or Time, that he finds waiting in a barbershop.  Clearly, Barthes argues, this is propaganda for French colonialism, the young black soldier’s salute signifying not only loyalty to France, but that the French government and military are loved and supported by Africans, that “all her sons, without any colour discrimination, faithfully serve under her flag”.  The boy’s faith signifies the faithfulness of France to liberty, equality and community, as “Liberté, égalité, fraternité” is the national motto of France.

For Barthes, myth is depoliticized speech.  This means that only political and revolutionary speech is non-mythological.  Barthes, a Marxist, is here in line with Marx’s view that there is objective and scientific understanding, which is Communist and materialist, and there is ideological fiction, which is everything else.  In this, Barthes fails to see Marxism or Communism as incapable of mythology or mythologizing, and yet he writes, “the press undertakes every day to demonstrate that the store of mythical signifiers is inexhaustible”.  Barthes saying that only revolutionary political thought is non-mythological is very similar to Positivists saying that only mathematical science is rational or meaningful.

Michel Foucault (1926 - 1984) is now a celebrated and well studied thinker, not only in philosophy but also in history, sociology and political science.  In his final years he taught at Berkeley, a reason he is particularly popular in this town.  His books are critical historical studies of social institutions and practices such as prisons, psychiatric hospitals, science and sexuality.  Foucault called himself a Nietzschean and Heideggerian, and his critical philosophy centers on the idea of the human tendency to privilege what is labeled as good while marginalizing and dominating what is labeled as evil.  Foucault went on vacation to the French Riviera and then stayed in his hotel room the entire time reading Nietzsche, whom he had not yet read, overcome with his criticism of all institutions.  Foucault was already a psychiatrist and gay at a time when psychiatry considered homosexuality to be insane, calling it gender identity disorder, which is still applied to transexuals but no longer homosexuals.  Foucault became fascinated with the complexity of good and evil Nietzsche unearthed, not merely as morality but as ‘sane’ and ‘insane’ in the history of psychiatry, of ‘normal’ and ‘perverse’ in the history of sexuality, of ‘legal’ and ‘criminal’ in the history of justice and prisons.

Foucault is deeply critical of any claim to absolute or objective knowledge, distrusts binary dichotomies such as good/bad, true/false, opinion/knowledge or sane/insane, and understands truth as a struggle between competing forces, institutions and interpretations.  Like Barthes, Foucault argues that truth is complex and historical, but ideology attempts to mask this by presenting clear exclusive divisions between opposites.  Institutions must support binary divisions to maintain power and pronounce themselves objective holders of genuine knowledge and truth.  This bends our view of reality such that the dominant system (religion, science, politics, etc) is simply identified with truth and the messy historical process and evolution of systems of thought is obscured.  On one side, giving an institution the right to distinguish the sane from the insane is quite sane and sober.  On the other, when one looks at the complex history of uses and abuses of these categories, one can find much that is outright insanity.  Are the institutions sane or insane, just or unjust?  How can we know so simply, when these institutions determine their own sanity, their own ability to be good or embody justice and truth?

For Foucault knowledge is always involved with serving power, just as for Nietzsche truth is always involved with serving desire.  We have all heard ‘Knowledge is Power!’ as a good thing, but for Foucault knowledge is not only enabling power, it is at the same time repressive domination, a contradiction we and the institution would often like to ignore.  Truth is not outside power, but is a thing of this world.  Just as for Nietzsche, institutions and their systems of thought grow and thrive on opposition and problems.  Foucault held a chair in “History of Systems of Thought”, a position created especially for him and one that I quite admire.

As mentioned last time, science, such as psychiatry, serves powerful interests while baptizing itself as disinterested objective truth, and the average person believes that they are smart and free for believing what they are told in a magazine rather than understanding the complicated and brutal process of various forms of truth that compete with each other.  Foucault believes that we should push for what we want and strive for greater understanding while knowing that we are naturally greedy, abusive, marginalizing, and ignorant.  Power is not just a negative thing, but everything, so the form of the bad is the form of the good.  One can see the influence of Nietzsche and a philosopher who is “beyond good and evil”.  Thus, communists who declare themselves to be liberators are also oppressors, and people who feel oppressed by society are also helping to oppress themselves through their own individual fear and desires.  Human nature is neither good nor evil, but the two together.

Foucault studies the complicated historical situations when one form of power, knowledge and dominance shifts to become another form as circumstances change.  A dominant theme of his work is that with industrialization people have to learn to police and dominate themselves and the authorities have to convince them that it is their own idea and independence.  Marcuse describes something similar in One-Dimensional Man.  The famous metaphor Foucault uses is the Panopticon, a prison designed by the philosopher Bentham, teacher and friend of the utilitarian John Stuart Mill.  The Panopticon is a prison designed so that everyone can see that they are possibly being watched, but they can see little other than this.  Never knowing when they are being watched, never seeing their observers, they learn to behave as if they are always being watched, and thus even without any guards they learn to police themselves and be constantly in self-conscious anxiety.  Consider current legal issues with police filming everything but opposed to being filmed themselves.

Foucault is concerned with showing the structures of power as they grow from what he calls the capillary level, the tips of the branches, the experiences of individuals, up through the dominant institutions, cultures and identities.  While this is quite Structuralist, very much a description of history and sociology that presents itself as the record and truth, Foucault seeks to constantly subvert our perspectives and the institutions, to show that what we try to marginalize consequently becomes quite dominant.  The insanity, brutality and evil that we seek to overcome, that we try to lock away in the asylums and prisons, that we try to barricade against through walls and warfare, becomes the new manifestation of contradiction and chaos, the new complex that continuously strives to overcome itself while simultaneously remaining blind to its own actions.

Introduction to Philosophy: Wittgenstein

Ludwig Wittgenstein (1889-1951) is one of the most important thinkers in academics today.   His early book, the Tractatus, and his later book, the Philosophical Investigations, are considered two of the most important influences for the American and British Analytic school of philosophy, the dominant school of philosophy in America.  In an end of the century poll in 2000, philosophy professors from America and Canada were asked to list the five most important books that influenced their own work.  When all of the results were tallied up, the Philosophical Investigations was #1, and the Tractatus was #4.  The Philosophical Investigations was cited far more frequently than any other book, was listed first on far more ballots, and crossed over more into many different disciplines and areas of study.

Wittgenstein’s thought can be divided into his early, middle and later work.  His early work is the book the Tractatus, the book which gave the world truth table logic.  This tool, as Wittgenstein later came to see it, remains the mathematical system taught as logic today.  Just as Wittgenstein became famous for his truth tables, he switched positions in his thinking and came to reject his earlier work.  He wrote in notebooks that were only published after his death, and the Philosophical Investigations is the most celebrated of these.

Wittgenstein’s Father was the Austrian Carnegie, making a fortune in Steel.  Though his father was Protestant, and his mother Jewish, Ludwig was baptized Catholic because of antisemitism at the time.  In his early years, Ludwig was a proud atheist but by the time he was working on his Tractatus he had a mystical transcendental outlook which he kept for the rest of his life.  Though never religious, and though he had to bribe Nazis later to smuggle his “Jewish” family from Austria, he was buried as a Catholic.

The Wittgenstein family was known for intense criticism, musical talent, depression, and suicide.  Three of Wittgenstein’s four brothers committed suicide, and he himself considered suicide for awhile before launching into his late period.  Unfortunately, suicide was considered romantic for Austrian elites at the time.

Wittgenstein was in Hitler’s elementary school, 2 days younger, but because he was put forward a grade and Hitler was held back a grade he was 2 years ahead.  Both he and Hitler hated the school and the lessons.

He began studying at university in Berlin to become an engineer with an interest in flight (the Wright Brothers had recently invented the motorized glider, but flew it in France and Germany until 1907 as the US Army did not believe them).  After failing in his attempt to build a better propeller, he began studying mathematical theory and philosophy of mathematics, becoming entranced with two thinkers who are along with Wittgenstein foundational for Analytical philosophy and logic:  Russell from Britain, and Frege from Germany.  Wittgenstein went to see Frege, who did not fully understand his questions and advised him to go see Russell, which he did in 1911.

He showed up unannounced to Russell’s room at Trinity College, impressed him with his intense and brilliant arguments.  Russell became convinced that the young Austrian was going to carry his work forward and be his successor, solving the remaining problems of logic that Russell’s work on the foundations of mathematics had left open.  As mentioned last lecture, Russell had shown there were contradictions unresolved in Frege’s work with set theory, but Russell had become frustrated trying to solve these contradiction with his theory of types.

Wittgenstein, an eccentric and difficult personality, was never fully comfortable at Cambridge, and often got into disagreements with Russell and threatened to leave many times before fleeing to Norway where he believed he could finish his work on Logic.  While some still disagree, it is generally accepted that Wittgenstein was gay, developed a relationship with Pinsent, a young graduate student, and some believe that Russell encouraged the relationship if he did not introduce the two with the purpose of keeping the emotional and unstable genius with him at Cambridge.

When WWI broke out, he served for Austria, at the same time as he was developing the material for the Tractatus.  Learning of Pinsent’s death in the war in Italy, he became suicidal, moved in with his uncle and finished the Tractatus which he dedicated to his ‘friend’ Pinsent.  He tried to get it published, but no one would take it.  Remember: this book went on to be the #4 influence in the US and Canada according to the poll, the book that gave modern logic truth tables, the method that replaced Aristotle’s syllogisms.

Russell intervened back in Cambridge, and had it published and wrote and introduction for it.  This was the start of the end.  Though Russell saw the work as genius, he did not completely understand much of it and his introduction reflected this.  Wittgenstein read the introduction and realized Russell had great misunderstandings of his work.  Believing that his Tractatus had solved all the problems of philosophy, Wittgenstein left Russell and Cambridge again and went to be a school teacher in Austria.  He gave away his portion of the family fortune, anonymously to writers but also to his family.  Since his family was already wealthy, he wrote in a letter, “they won’t be corrupted by it”.  He left the school after a short while (not a good fit, and parents thought he was crazy).  He became a gardener’s assistant, and then his sister had him design her a house.

While finishing the house, he was contacted by members of the Vienna Circle, positivists using Hegel’s logic and Wittgenstein’s Tractatus to give a solid foundation for science and mathematics.  This was what Russell had hoped for, minus the Hegel who Russell hated.  While Wittgenstein had been away, the Tractatus had become famous, and central to many already inspired by Frege and Russell.  Many came to visit and discus and progressively Witt became disgusted.  He began to realize that there were fundamental problems with his Tractatus and truth tables, and got into intense arguments with the Vienna Circle members, at one point turning his back on his guests and reading Tagore, an Indian transcendental poet out loud.  For the rest of his life, Wittgenstein thought logical positivism (the analytic school of philosophy) misunderstood his Tractatus.

In his early period, Wittgenstein believed he had fully solved the problems of a complete system of logic.  He saw it like Schopenhauer, a big early influence: logic is a perfect crystal tool of analysis, life is a messy chaotic ocean, and so logic is perfect but unfortunately never fits perfectly with life.  This is like having the perfect tool for an impossible and continuous job.  In conversations with positivists he started to change his thinking around and continued to write until he died.  These writings were published after his death as the Philosophical Investigations and other books.  In his later thought, Wittgenstein saw logic not as a perfect crystal castle in the sky but as rules and games that are imperfectly lived in the real world imperfectly and without complete definition. He no longer believed that logic could provide a foundation for mathematics, science or philosophy.  He denied that contradictions are necessarily false, or disprove a mathematical-logical system.

In 1929, he decided to return to Cambridge to correct his thinking and teach.  To his horror, when he arrived at the train station he was greeted by a vast crowd of intellectuals as the new hero, the author of the Tractatus, the work he now thought was exactly wrong.
The famous economist Keynes wrote to his wife: ‘Well, God has arrived.  I met him on the 5:15 train’.  Wittgenstein continued to lecture at Cambridge, developing his ideas.

In 1934, he defected to Soviet Russia, wanting to be a plumber or work with his hands.  When he was told that according to the Soviet system he would be put to work as a philosophy professor in Moscow, he defected back to Britain.

In 1937, Hitler annexed Austria.  Wittgenstein had to bribe Nazis to get his Jewish family passage out and spend the equivalent today of $50 million in gold and foreign currency.  Since he had given away his own portion of the family fortune, he had to get much of this from his colleagues at Cambridge and other admirers of his work.


THE TRACTATUS

In his early thought, expressed in the pages of the Tractatus, reality consists of atomic facts, states of affairs that are true.  Thought, expressed grammatically in language, ‘pictures’ the world with these atomic facts.  The world does not perfectly fit this atomic language, but because it is the way the head makes sense of the world we cannot understand things otherwise.   Wittgenstein said that it is the part of the book that is unwritten that is important, the part where life itself goes beyond this logic and makes the world what it is.  Of the world beyond logic, he wrote “Of what one cannot speak, one must remain silent”, which is in fact a quote from Confucius.  Our logic and the world are two things that do not fit, yet mysteriously (and mystically) the two are one.

If we boil logic with truth tables down to its tautologies, the necessary and basic workings, and leave the rest open as the world which always is beyond our thoughts, we can have the perfect system of logic and grammar that we use to understand things spelled out even if it cannot perfectly predict the world or tell us how the world works.  Think of logic as a set of reading glasses, and the world as something one looks at through the glasses.  Wittgenstein believed that with the Tractatus he had spelled out the perfect crystal form of the glasses, and beyond this nothing can be said for certain.

When it comes to facts in the world, however, everything is contingent on something else and is neither simply necessary or simply impossible.  Logic is the necessary and impossible book-ends with which we interpret the world and its facts, but the world is always between the necessary and the impossible, is always somewhat necessary and somewhat impossible, which creates a gulf between our pure and necessary logic and the unpredictable world.  For Wittgenstein, only logic and math can be sets of necessary truths, and this is because (as Avicenna and Mill believe) they are concepts and are ideal, unlike situations of real things in the world.  Once we nail down the perfect tool of logic, we can use it to examine the world and all of its messy situations.  Our examinations will never be perfect because of the gap between logic and the world, but at least the logic will be necessary and perfect.

The reason’s Wittgenstein’s truth tables were such a success is that they proved, for the first time, that many of the axioms logicians had discovered were necessarily true (tautologies) in a way that is simple to do and easy to see.


THE MIDDLE AND LATER THOUGHT OF WITTGENSTEIN

At first Wittgenstein thought that he had solved all the problems of philosophy with the Tractatus truth table system (we do still use it today to teach formal logic), so he left philosophy and Cambridge behind, went to war, had many experiences, and then later decided that his earlier thinking contained horrible problems.  He no longer believed that logic could be crystallized in the head as a truth table matrix, but rather it existed as a complex out in the world, as arrangements of people, thoughts, symbols, and objects.  He continued to work on notebooks, progressing in his thought until his death, after which his notebooks were published.

There is an excellent passage from Lectures and Conversations that illustrates the turn nicely.  This work was taken not from Wittgenstein’s notebooks but from the notes of his seminar students in the years leading up to his work on the notebooks which would be published after his death as the Philosophical Investigations.  At this time Freud’s ideas had stormed onto the academic scene, infuriating Wittgenstein who now had come to hate the idea that things in the world, even logical operators and systems, can be boiled down to a single essential element or factor like sex, power or truth.  It is this skepticism, which can be called the “problem of essences”, which marks the turn from his earlier thinking to his more influential later thought.

Wittgenstein attacked Freud’s psychoanalysis and dream interpretation for boiling everything down to sex.  In the Lectures and Conversations (20-21), Wittgenstein proposes a thought experiment for consideration.  If we cook a human being down to carbon ash in an oven, are we left with the essence of the human being?  A human being is a “carbon-based” life form, so carbon is a dominant element.  Consider that we could cook a human down to water in the same oven, and claim that because humans are 3/5ths water we have the essence of the person.

Would it be correct to say that humans are essentially ashy, or essentially wet?  Why not?  We would not say that a human is essentially carbon or water, nor would we say ashy or wet, because the human being is a complex situation that is not reducible to a single element.  The properties of carbon or water do not in themselves explain how humans behave or what they mean to us.  If we cooked people down to ashes or water, we have destroyed the situation and can no longer investigate how they work.  In the same way, a person is not merely their DNA.  While carbon, water and DNA have very important, even necessary roles to play in any person, they are not exclusively the essence or meaning of the complex that is a human individual.

In the same way, Wittgenstein had come to believe that neither facts in the world nor logic in the head can be reduced to a single element or necessary structure.  Facts and logic are not true in themselves, but true in real situations of the world which are irreducibly complex.  Wittgenstein says in the Lectures and Conversations that we have to avoid the “lure of the secret cellar”, the urge to boil situations down to a single element like Freud tried to boil human relations, meaning and the mind down to sex or Wittgenstein himself had tried to boil logic down to its simple structure.

The task of philosophy, logic and science is not to fully or completely explain anything, but to investigate things.  Thought never fully defines things but rather describes and re-describes things.  If science is thinking about the world, then science has endless work to do describing and re-describing things.  Consider whether we fully understand apples, or whether we ever need to entirely understand them in order to continue to understand them and use them a great deal.  Likewise, if philosophy and logic are ‘thinking about thinking’, and if thinking is merely a possible description of things, philosophy and logic have endless work to do describing our descriptions, describing and re-describing the ways that we describe things.  Much insight can be gained even if no subject is entirely explained or exhausted.

One good way to approach this is to describe how cultures of thought, perspectives, facts and models are gathered together and lived in institutions.  Thought ceases to be completely abstract, but is rather a culture and situation in the real world that involves people, buildings and money.  The cryptanalysis of algebra worked so well as a modeling language that we came to believe that the mathematics was not in our practices and text books but rather sewn into the fabric of the world itself.  As we look over the history of thought in the wake of Wittgenstein’s later work, it becomes evident that mathematics and logic are tools and lenses, not the hidden structures of things operating at secret levels out of our immediate sight.  In scholarship today, particularly the history of religion, philosophy and science, it has become popular to consider a system of thought as a real lived situation rather than an abstract set of beliefs and ideas.  A religion or science is in fact a situation of human beings who never have to have entirely the same set of beliefs as long as they can generally and relatively cohere as a culture.


THE PHILOSOPHICAL INVESTIGATIONS

In this monumental work, one of my favorites of modern European thought, Wittgenstein argues for a middle way between two extreme positions, between the position of scientific positivism (objective truth is facts in the world) and the position of psychological skepticism (subjective truth is meanings in the mind).  He presents each position in quotes again and again, and then argues against both in a three stage process.  First he states a position (either that there are facts given in the world or meaning is all in the head), then shows situations in which the position works, then shows situations in which the position does not work.  He shows us that taking either position to extremes would be understandable given particular ways we think and act, but neither position explains all the ways in which we think and act.  We live in complex ways that depend both on there being a coherent world and there being human perspectives.  Wittgenstein argues that we can take both positions rather than determine one to be the actual and the other to be the illusion.

In his earlier thought, the world and the head are separated by a Kantian gulf between objectivity and subjectivity.  In his later thinking, the world and our heads work together seamlessly as a complex situation.  One cannot remove either the head or the world to get the bedrock or anchor of meaning and truth without resulting in absurdities.  The clean and ideal side of logic, math and grammar mislead us into thinking that meaning must be anchored entirely on one side, either exclusively in the head or exclusively in the world, but we gain much more ability to think and describe our heads and our world if we stop looking for meaning and truth to be entirely in one place rather than the other.  In the same way, rather than determine which facts are absolute truths to the exclusion of their opposites, or refuse to identify coherence of belief as it is all ‘mere theory’, we can better understand the facts and theories we can share by recognizing that they are one and the same viewed from opposite sides.  If we can continue to determine relative fact from relative fiction, there is no need to entirely separate the two.  To use the tool analogy, as long as we have decent tools we do not need perfect or eternal ones.

Games and rules gather people together, but individuals can also variously interpret rules and meanings.  ‘Rules can always be variously interpreted’ is a central idea of the Philosophical Investigations.  This is not to say that they always are or they should be, but the window remains open (Wittgenstein writes, “It is like locking a man in a room but leaving the window open”).  Both are only what they are together as a form of life.  Notice that this thinking has much in common with Laozi’s thinking on the wheel as both empty and solid at the same time, and much like the Zen koans of a rock being not a rock and a rock and the sound of one hand clapping.

Consider the ‘child at the blackboard’ metaphor used in the text.  It is always possible for a child to misunderstand rules and demonstrate this misunderstanding by making mistakes, even after you show the child and explain.  Let us say that you then write a new ‘inner’ set of rules to further explain the rules when the child fails.  What if the child does not understand those?  Is there a bedrock set of rules that the child can not possibly misunderstand?  If the child can misunderstand rules, then no set of rules within rules within rules is ever perfectly airtight.  We have an infinite regress unless we can find a set of rules that can never be misinterpreted.  

Just like Wittgenstein had been seeking the fundamental inner workings of logic and mathematics, as Frege and Russell had tried to do before him, if people do math decently there need not be any inner rules aside from the explanation and demonstration that, if repeated, children can often follow.  Notice we are considering mathematics as a culture, learned by children and taught by adults, not as an abstract set of necessary or immutable rules.  It turns out that there are no inner workings to mathematics.  Mathematics works as it does openly, on the board in front of one’s face, without the need of a ‘secret cellar’.  If mathematics on a board is not entirely secure, then no inner set of rules could or must be either for it to function.

When we try to explain anything, it is not being simplified, being stripped down to its core, at all.  It is the opposite: we are making it more complex as we try to simplify and explain it.  The rules are not being discovered in the thing, but being added to the thing.  When we explain things, we are not whittling away the unnecessary but adding our descriptions to it.  In the same way, when we do science to explain apples or human beings, we are adding our descriptions and the situations of our descriptions, not uncovering the simple truth of the thing.  The simple truth of a thing is the simple thing itself.  The simplest truth of an apple is the single apple.  An explanation of where apples come from is very useful, but it puts the apple in a complex with many other things (such as trees, farms, stores, trucks).  An apple is not merely its DNA, but is in a infinitely complex situation with its DNA and ourselves attempting to isolate components with the tools and technology we bring into the situation.

We are always essentializing (like when we say, ‘We are always essentializing’).  Meaning, grammar and logic do separate things into parts.  They are useful for doing so.  However, Wittgenstein is arguing something quite revealing: There are no final explanations, only complex descriptions.  Any explanation is a partial human description, which can then itself be described and explained.  The task of philosophy, science and mathematics is not to reduce things to simple truth, but to generate more meaning and situations.

Let us turn to the text.  In the preface to the Philosophical Investigations, Wittgenstein says that he now sees grave mistakes in his Tractatus.  He says that this new book is not to spare thinking, but to stimulate thinking.  Notice that the Tractatus had the opposite goal: to put an end to the problems of logic and philosophy.  Now Wittgenstein does not believe that anything can or need be fully solved or closed, but should rather be opened up and made complex.

In section 7, Wittgenstein says that language games are actions and language interwoven as forms of life.  He considers that words such as ‘this’ and ‘there’ are learned interwoven with gestures such as pointing.  ‘This’, ‘now’, and other simple words get their meaning from their use by gesturing human beings.  They can not be described fully in language alone, nor do they represent specific objects consistently.  Rather, they are demonstrated to children and translated into other languages of cultures that share similar gestures.  We know from neuroscience that in the brain the centers of language and control of the hands are next to each other, likely because language developed in apes along with gestures.  There are also similarities in the basic gestures of humanity, including extending the arm to indicate the direction of sight and attention.  Infants only months old will read eye direction to try to see what others are seeing, and if they can not see what is being looked at they will check the eyes again.  The arm, whether a culture uses the index finger or not, provides an extension of the line of sight so that it can be easily recognized and followed by others.  Notice that ‘this’ is as simple as it gets in itself, and to further explain it we need to bring arms and neuroscience into the picture.

In section 11, he says language is like toolbox, a complex set of tools that have no absolute necessity but are useful as a set.  Consider that a hammer, a screwdriver and glue are a decent set of tools.  Are they absolutely right or necessary tools?  We could invent others, but they work decently well for putting things together and taking things apart.  We do not need an absolute screwdriver any more than we need to completely understand the relationship between the hammer and screwdriver.  We need only use them.  In the same way, we do not need to understand the word ‘and’ such that it is always used exactly the same way, nor do we need to completely understand its relationship to ‘or’.  When we use them relatively, not exclusively, they are interchangeable.  At a buffet, I could equally say, “You can have eggs or salad or steak” or “You can have eggs and salad and steak”.  The two can sometimes be used differently and sometimes similarly, as long as we are decently consistent in all of our interconnected uses.  Indeed, the words, like tools such as hammers and screwdrivers, are more useful being often but not always used in particular and exclusive ways (ex: one can use a screwdriver to open paint cans).  ‘And’ and ‘or’ are more useful when we can use them oppositely, but also identically.  In his earlier thinking, with the truth tables, Wittgenstein was trying to secure them merely opposite and different meanings, which does not give us their full usage and meaning.

In section 12, Wittgenstein uses the metaphor of a locomotive cabin to further illustrate the same point.  There are many levers and switches that function in various ways.  Words and language function in various ways that form a complex with their environment.  We could always redesign the train cabin, but it works well enough as it is.

In section 15, he uses another simple tool-oriented metaphor to make language and meaning physical rather than ideal: naming is compared to attaching a label (or sticker, with “Hello My Name Is”).  The association of a word with a particular thing is like attaching a label for ease of use and identification.

In section 17, he says that we can classify words as we do things, but our classifications will depend on our situation and purposes.  He uses the metaphor of chess pieces.  If you want to move a great distance, you would classify chess pieces one way, but if you want to break through or jump over the enemy lines (with a knight or a bishop) you would classify them another way.  The pieces, like words and other things, do not have classifications and meanings in themselves, but in how they can be used in concrete situations.  This is again much like Mill.

In section 18, he says that a language is like an old city, with side streets and squares.  It is interesting to compare San Francisco to Salt Lake City here.  San Francisco can be a nightmare to drive, while Salt Lake City is almost entirely a perfect grid surrounding the Mormon Temple.  In San Francisco, you never know which way a street might turn due to hills or other intersecting streets.  European cities are similarly often much older than the automobile, and do not lend themselves to outsiders’ easy navigation.  A language, like an old city or old growth forest, is the result of a long process of many layers of evolution and development.  We can understand meanings just as we can navigate streets, but things are not always clear cut as Salt Lake City.

In section 57 and 58, he asks about where ‘red’ exists.  He suggests that ‘red’ as a color does not exist in itself, but as an association of many red things having been experienced, the word ‘red’ being said by others and oneself associated with these things, as well as the imagination/projection of the color red in the mind.  None of these things needs to be exclusively present for there to be red.  We could even say the word without any red things or thinking of red, and it still means the color in our language and culture.  We could likewise see a red thing, and it is red without using the word or seeing red in the imagination.  Thus, the color red is not essentially any red thing, or the word, or the color in the mind, but the complex of all these.  The color red is not simply a subjective concept, nor it is an objective fact, but it is a conception and association of many things and words, both in the head and the world together.

In section 65, Wittgenstein argues that there is no form common to language games or forms of life, such as the color red or the use of a tool.  The common element is merely form, or association.  In the same way that Hegel argues that Being itself can not be qualified (green, good, necessary) or quantified (much, fourteen, half), Wittgenstein argues that there is no common form to meaning.  It is a complex association that can take any possible form.  This is similar to the organic forms of fractal geometry: No two trees are identical, but they share what Wittgenstein calls a ‘family resemblance’.  In the next section (66), he uses the example of games.  There is no rule common to all games, but they resemble each other as a family.  

In the next section (67), he uses the metaphor of a thread (one could also use a rope).  The thread is strong not because there is one underlying strand that runs through its entire length, but because many stands overlap each other.  Mathematics and the meaning/use of a word do not need a single inner rule to make them entirely consistent.  Rather they are complex networks that are continuously reinforced by our re-inscription as we use them daily.  Derrida, the French deconstructionist, argues that there is no language set in stone.  Old English, like Old French, drift slowly like tectonic plates.  When we use language, we are not using something already set.  Rather, we are resetting it, re-associating it, re-gluing it together with the only glue it was ever fashioned from, each and every time we speak or write.  Likewise, mathematics such as algebra is not true in itself.  We continue to use it consistently, and this rebinds its consistent use.  When dividing by zero creates problems, we add additional rules and then continue to lash them together with the system.

In section 83, Wittgenstein gives another metaphor to describe the emergence (a chaos-theory, fractal geometry term) of forms of life.  Imagine people in a field, playing with a ball.  The ball is tossed about, another person joins and kicks it back to another, who chases it, then pegs the kicker with the ball, and then it is tossed about again.  A game has arisen, but it does yet does not seem to have consistent rules.  It is being made up as it goes along.  Human beings are rule making, association generating beings, who know how to follow and bend rules as they see fit.  This means that the only complete consistency is both consistency and inconsistency, the only consistent rule is there are yet there are not consistent rules.

In section 85, he gives another metaphor to back up this conception.  A rule is like a signpost, such as a sign that points to the right and reads, ‘San Jose’.  Does the sign force you to go to San Jose? No.  If you go to the right, will you surely reach San Jose without getting lost or running out of gas?  No.  We can even imagine that if you go to the left, because you are afraid of San Jose, you could get turned around and end up there anyway.  In spite of these loose ends, we find signs quite useful.

In section 99, he comes to the previously mentioned ‘locking a man in a room but leaving the window open’ metaphor.  You can not lock someone in a room such that they can never get out.  There are no simply solid substances.  There are no things without cracks of any kind.  Similarly we can not secure meanings such that they will always stay exactly the same, but we can secure them by locking them down repeatedly through use and association.  To give an entire account of how a meaning is secured would be like “repairing a torn spider’s web with one’s fingers” (106).  Just like an old city, we can use things without ever being able to fully describe them.

Wittgenstein writes, “We must do away with all explanation, and description alone must take its place” (109)...”What we do is to bring words back from their metaphysical to their everyday use” (116)...”What we are destroying is nothing but houses of cards and we are clearing up the ground of language on which they stand” (118).

Do we base our own behavior, let alone the culture of mathematics, on simple rules?  He gives the example of being certain that a table will resist one’s finger, that a fire will hurt one’s hand.  It is not that there is a simple rule set in an atomic language that reads, ‘Table is solid’ or ‘Fire hurts hands’.  Rather, “a hundred reasons present themselves, each drowning out the voice of the others” (478).  Like the thread woven of many strands, our belief and certainty that objects are solid and flame hurts us are woven out of many experiences that are then woven together with the table and flame before us.

Wittgenstein writes, “To say, ‘This combination of words makes no sense’ excludes it from the sphere of language and thereby bounds the domain of language.  But when one draws a boundary it may be for various kinds of reason.  If I surround an area with a fence or a line or otherwise, the purpose may be to prevent someone from getting in or out, but it may also be part of a game and the players be supposed, say, to jump over the boundary” (499).  Wittgenstein seems to be thinking specifically of humor and comedy, though it could also apply to modern and conceptual art, forms of culture that break rules on purpose.  Comedy and modern art are games where the rule is to break the rules without breaking anyone’s neck.  Wittgenstein had an appreciation both for the Alice books of Lewis Carroll as well as American slap-stick comedy which he preferred to opera.  At the end of the course, we will study the Alice books, humor and modern art in light of the later work of Wittgenstein.

The last image to examine, near the end of the book, is Jastrow’s duck-rabbit, often called Wittgenstein’s duck-rabbit because the psychologist Jastrow is far less famous.  One can look at the figure from the left, and it is a duck, and one can look at the figure from the right, and it is a rabbit.  Which is the single correct face?  Wittgenstein says we may have seen only the rabbit face our entire life, and that does not prevent us or others from seeing the duck when it is pointed out.  This is much like the duel between objectivism (truth is in the world) and subjectivism (meaning is in the head).
