More Carnap and Some Raymond Smullyan

Rudolf Carnap, what a card. Eric Schliesser sums it up with a reference to Carnap’s infamous “The Elimination of Metaphysics“:

In the history of philosophy, “the nothing itself nothings,” has, of course, a dubious status as either brilliant ridicule or very uncharitable reading. But as Stone has taught us, in context that sentence is a very charitable reading of Heidegger. No, the real insult to Heidegger occurs near the end of Carnap’s (1931) paper [I have linked to an English translation]. Carnap ends his paper (which is rarely read, but often cited) with a two-fold insult to Heidegger: first, “Metaphysicians [that is, Heidegger] are musicians without musical ability.” (Cf. Heidegger’s Stimmen in “What is Metaphysics?”) Second, Carnap THEN GOES ON TO PRAISE NIETZSCHE and his poetry. To say this as a serious joke: Heidegger’s lecture courses on Nietzsche are a response to Carnap’s two-fold insult.

His ingenuous waggery reminded me of this story that Raymond Smullyan tells about Carnap:

In item # 249 of my book of logic puzzles titled What Is the Name of This Book?, I describe an infallible method of proving anything whatsoever. Only a magician is capable of employing the method, however. I once used it on Rudolf Carnap to prove the existence of God.

“Here you see a red card,” I said to Professor Carnap as I removed a card from the deck. “I place it face down in your palm. Now, you know that a false proposition implies any proposition. Therefore, if this card were black, then God would exist. Do you agree?”

“Oh, certainly,” replied Carnap, “if the card were black, then God would exist.”

“Very good,” I said as I turned over the card. “As you see, the card is black. Therefore, God exists!”

“Ah, yes!” replied Carnap in a philosophical tone. “Proof by legerdemain! Same as the theologians use!”

Raymond Smullyan, 5000 B.C. and Other Philosophical Fantasies

[I read Smullyan’s books of logic puzzles when I was a kid and recommend them to all parents. I always enjoyed them until he started talking about Gödel’s Incompleteness Theorem, at which point my brain melted. I’m not sure if I was mentally capable of understanding logic to that extent at a young age, regardless of how it was explained.]

It’s possible that if Heidegger had more anecdotes like this, I might feel more fondly toward him. But let’s hear more of Carnap’s words and his praise for Nietzsche, where he seems to in part be channeling Cassirer as well as a bit of Wittgenstein. Metaphysical systems are myths, he says, they are forms of life.

I thought of editing this down but it’s lovely enough that I decided just to quote the entire concluding section:

Our claim that the statements of metaphysics are entirely meaningless, that they do not assert anything, will leave even those who agree intellectually with our results with a painful feeling of strangeness: how could it be explained that so many men in all ages and nations, among them eminent minds, spent so much energy, nay veritable fervor, on metaphysics if the latter consisted of nothing but mere words, nonsensically juxtaposed? And how could one account for the fact that metaphysical books have exerted such a strong influence on readers up to the present day, if they contained not even errors, but nothing at all? These doubts are justified since metaphysics does indeed have a content; only it is not theoretical content. The (pseudo)statements of metaphysics do not serve for the description of states of affairs, neither existing ones (in that case they would be true statements) nor nonexisting ones (in that case they would be at least false statements). They serve for the expression of the general attitude of a person towards life (“Lebenseinstellung, Lebensgefühl”) .

Perhaps we may assume that metaphysics originated from mythology. The child is angry at the “wicked table” which hurt him. Primitive man endeavors to conciliate the threatening demon of earthquakes, or he worships the deity of the fertile rains in gratitude. Here we confront personifications of natural phenomena, which are the quasi-poetic expression of man’s emotional relationship to his environment. The heritage of mythology is bequeathed on the one hand to poetry, which produces and intensifies the effects of mythology on life in a deliberate way; on the other hand, it is handed down to theology, which develops mythology into a system. Which, now, is the historical role of metaphysics? Perhaps we may regard it as a substitute for theology on the level of systematic, conceptual thinking. The (supposedly) transcendent sources of knowledge of theology are here replaced by natural, yet supposedly trans-empirical sources of knowledge.

On closer inspection the same content as that of mythology is here still recognizable behind the repeatedly varied dressing: we find that metaphysics also arises from the need to give expression to a man’s attitude in life, his emotional and volitional reaction to the environment, to society, to the tasks to which he devotes himself, to the misfortunes that befall him. This attitude manifests itself, unconsciously as a rule, in everything a man does or says. It also impresses itself on his facial features, perhaps even on the character of his gait. Many people, now, feel a desire to create over and above these manifestations a special expression of their attitude, through which it might become visible in a more succinct and penetrating way. If they have artistic talent they are able to express themselves by producing a work of art. Many writers have already clarified the way in which the basic attitude is mani-fested through the style and manner of a work of art (e.g. Dilthey and his students). [In this connection the term “world view” (“Weltanschauung”) is often used; we prefer to avoid it because of its ambiguity, which blurs the difference between attitude and theory, a difference which is of decisive importance for our analysis.] What is here essential for our considerations is only the fact that art is an adequate, metaphysics an inadequate means for the expression of the basic attitude.

Of course, there need be no intrinsic objection to one’s using any means of expression one likes. But in the case of metaphysics we find this situation: through the form of its works it pretends to be something that it is not. That the metaphysician is thus deluding himself cannot be inferred from the fact that he selects language as the medium of expression and declarative sentences as the form of expression; for lyrical poets do the same without succumbing to self-delusion. But the metaphysician supports his statements by arguments, he claims assent to their content, he polemicizes against metaphysicians of divergent persuasion by attempting to refute their assertions in his treatise. Lyrical poets, on the other hand, do not try to refute in their poem the statements in a poem by some other lyrical poet; for they know they are in the domain of art and not in the domain of theory.

Perhaps music is the purest means of expression of the basic attitude because it is entirely free from any reference to objects. The harmonious feeling or attitude, which the metaphysician tries to express in a monistic system, is more clearly expressed in the music of Mozart. And when a metaphysician gives verbal expression to his dualistic-heroic attitude towards life in a dualistic system, is it not perhaps because he lacks the ability of a Beethoven to express this attitude in an adequate medium? Metaphysicians are musicians without musical ability. Instead they have a strong inclination to work within the medium of the theoretical, to connect concepts and thoughts. Now, instead of activating, on the one hand, this inclination in the domain of science, and satisfying, on the other hand, the need for expression in art, the metaphysician confuses the two and produces a structure which achieves nothing for knowledge and something inadequate for the expression of attitude. Our conjecture that metaphysics is a substitute, albeit an inadequate one, for art, seems to be further confirmed by the fact that the metaphysician who perhaps had artistic talent to the highest degree, viz. Nietzsche, almost entirely avoided the error of that confusion. A large part of his work has predominantly empirical content. We find there, for instance, historical analyses of specific artistic phenomena, or an historical-psychological analysis of morals. In the work, however, in which he expresses most strongly that which others express through metaphysics or ethics, in Thus Spake Zarathustra, he does not choose the misleading theoretical form, but openly the form of art, of poetry.

Rudolf Carnap, “The Elimination of Metaphysics”

Karl Popper, among others, later complained that Carnap was giving away the store with this attitude. Perhaps he was. Shoving huge domains of life (including much of what falls under the rubric of “science”) out of philosophy and into the realm of art is not exactly a philosophy-boosting move, even if it taunts Heidegger.

Smullyan extends and somewhat reverses this line of thought as follows:

Suppose I have a world view that is internally perfectly consistent, that is, logically consistent, consistent with all the experiences I have ever had, and consistent with all my feelings and intuitions. For the moment, let us make the further assumption (totally unrealistic as it almost certainly is) that the view is consistent with any experience I ever will have in the future. Let us call such a view a perfect world view. Now suppose that you also have a perfect world view but that yours is logically incompatible with mine. It seems to me that the valuable contribution of the positivists (and, for that matter, the pragmatists) is the realization of the question, “How in principle could you or I ever show each other to be wrong?” In other words, can we really hope to get anything more from philosophy than consistency?

It could well be that our world views are in fact perfect, yet it might be consistent for each of us to deny that the other’s world view is perfect. (Indeed, it might even be consistent to deny that one’s own world view is perfect!) Actually, if I believed your world view to be perfect (though false), I think I am now sufficiently influenced by the positivists to realize that my arguing with you could be of no avail. Thus, I think that our very process of arguing with each other indicates our lack of belief in the perfection of each other’s world views; we hope either to show the other view to be inconsistent or to produce some new experience in the other person that will change his mind or call forth to full consciousness some latent intuition. This, I think, is what metaphysicians of the past have been up to. As Carnap has rightly pointed out, metaphysicians are not content just to present their systems (unlike artists and poets, who only present their works of art), but they try to refute the metaphysical systems of others. I have just proposed what I believe this refutation to really be.

The point, then, is, in mathematical language, to construct a model of your language within mine. Put less precisely, though more expressively, the point is for me to be able to see the world through your eyes. After having gone through such an experience, it is more than likely that my own world view might become considerably enlarged. After all, even in a perfect world view, one has not necessarily decided the truth of every statement; there may be many alternative ways of extending it to produce a more comprehensive perfect world view.

To the reader with some knowledge of mathematical logic, I acknowledge that I of course realize that my fanciful analogies have their weak points… But I believe that all I have said about perfect world views should apply a fortiori to those that are not perfect.

The technique of philosophizing that I am suggesting might be put in the form of a maxim: “Instead of trying to prove your opponent wrong, try to find out in what sense he may be right.” This is a sort of tolerance principle, not too unrelated to that of Carnap.* To repeat my main point, much may be gained from constructing possible models of other world views within one’s own. I believe that this is in the spirit of much of modern analysis. But I would like to see this applied more to some of the great metaphysical systems of the past.

*  Indeed, it can be thought of as a semantic counterpart of Carnap’s principle of tolerance. His principle says that a language should be regarded as acceptable if it is consistent–or equivalently, if it has a model. My principle is to try to find such a model–or rather an interesting model of the language.

Freud and Nude Psychotherapy for Criminal Psychopaths

One more addendum to the question of Freud and science. The gravest deployment of psychoanalytic theory was in psychopathology, and it’s here that I have the greatest trouble with Freud’s influence. Now, the history of the treatment of the severely mentally ill, in asylums and otherwise, has been generally dismal, and so it is hard to credit Freud with making things any worse on that front. Perhaps he even made them better, and to be sure Freud avoided the area himself, probably figuring it (correctly) to be a minefield. But as psychoanalysis grew, some of his followers were not so hesitant, and the application of psychoanalysis in psychopathology yielded some disturbing results.

There are no shortage of examples, but Oak Ridge recently came to my attention. As Jon Ronson tells it in The Psychopath Test:

Dr. Elliott Barker successfully sought permission from the Canadian government to obtain a large batch of LSD from a government-sanctioned lab, Connaught Laboratories, University of Toronto. He handpicked a group of psychopaths (“They have been selected on the basis of verbal ability and most are relatively young and intelligent offenders between seventeen and twenty-five,” he explained in the October 1968 issue of the Canadian Journal of Corrections ); led them into what he named the Total Encounter Capsule, a small room painted bright green; and asked them to remove their clothes. This was truly to be a radical milestone: the world’s first-ever marathon nude psychotherapy session for criminal psychopaths.

Elliott’s raw, naked, LSD-fueled sessions lasted for epic eleven-day stretches. The psychopaths spent every waking moment journeying to their darkest corners in an attempt to get better. There were no distractions—no television, no clothes, no clocks, no calendars, only a perpetual discussion (at least one hundred hours every week) of their feelings. When they got hungry, they sucked food through straws that protruded through the walls. The patients were encouraged to go to their rawest emotional places by screaming and clawing at the walls and confessing fantasies of forbidden sexual longing for one another even if they were, in the words of an internal Oak Ridge report of the time, “in a state of arousal while doing so.”

Jon Ronson, The Psychopath Test

Ronson’s book is unfortunately scattershot and unfocused, mostly good for anecdotal pointers. Richard Weisman wrote a far more detailed reflection on the Oak Ridge experiments. In either version, Barker  and Gary Maier and other empathetic psychiatrists display jawdropping irresponsibility..

Granted, this does not seem any worse than what one can read about in Foucault or, more vividly, in the horrific chronicles given by Erving Goffman in his amazing book Asylums and shown by Frederick Wiseman in Titticut Follies. (“Titicut Follies portrays the existence of occupants of Bridgewater, some of them catatonic, holed up in unlit cells, only periodically washed down with a hose and taken out in order to receive force feeding. It also portrays the indifference and bullying on the part of the institution’s staff.”) Humane treatment is a very recent invention and still practiced inconsistently.

If anything, Freud may have helped push forward increasingly humane treatment of the severely mentally ill, as manifested in Barker’s good intentions. But this does not excuse the rampant irresponsibility that was at hand at Oak Ridge, and Barker’s genial enthusiasm (he quotes Buber in “The Hundred-Day Hate-in”!) is in some ways even more frightening than the disdain, malice, and indifference that was historically the rule. The casual certainty that their mental model, derived primarily from psychoanalytic theory, would produce productive results is borne out of the same pool of certainty from which Freud drew capaciously.

Ronson gets one of his most disturbing quotes from one of the Capsule members named Steve Smith:

“I remember Elliott Barker coming into my cell,” Steve told me. “He was charming, soothing. He put his arm around my shoulder. He called me Steve. It was the first time anyone had used my first name in there. He asked me if I thought I was mentally ill. I said I thought I wasn’t. ‘Well, I’ll tell you,’ he said, ‘I think you are a very slick psychopath. I want you to know that there are people just like you in here who have been locked up more than twenty years. But we have a program here that can help you get over your illness.’ So there I was, only eighteen at the time, I’d stolen a car so I wasn’t exactly the criminal of the century, locked in a padded room for eleven days with a bunch of psychopaths, the lot of us high on scopolamine [a type of hallucinogenic] and they were all staring at me.”

I obviously cannot lay the full responsibility for Barker’s behavior or psychoanalysis’s influence on psychopathological treatment at Freud’s feet. Yet I cannot fully excuse it either. Freud’s model of the psyche became instrumentalized as an well-meaning institutional cudgel, and it could only have done so had it claimed such a scientific authority for itself.

Regarding that authority, George Makari (an avowed psychoanalyst himself) writes of the fight between Melanie Klein and Anna Freud’s psychoanalytic factions in England in 1942:

A talented member of Melanie Klein’s group named Donald Winnicott protested that Freud would never have wanted to “limit our search for truth.” He too asked the society to adopt language that put the aim of the group as the furthering of “the psychoanalytical branch of science founded by Freud.”

The Kleinians had taken the high ground of science, despite the fact that their leader had been accused of dramatically departing from basic scientific principles. Like the old Freudians, the Kleinians had become defenders of an empirically unknowable belief regarding unconscious mental life. Nonetheless, the Kleinians draped themselves in the principles of free inquiry. Like others before them, they seemed to want the freedom of scientific pursuit without accepting the responsibilities that came with it.

It is a hubris seen very frequently.

Alasdair MacIntyre on Freud: A More-than-Scientific Unification of Concepts

As a follow-up to Ernest Gellner’s attack on psychoanalysis, here is Alasdair MacIntyre with a more charitable critique of Freud.

Up until the time of After Virtue (still a fascinating book), MacIntyre was a fairly keen observer of ethics and social philosophy, as well as an enviably clear writer. I suppose he still is, but since the time of his conversion to Catholicism in the 1980s, his increasing focus on religion and increasingly tendentious positions have had much less to offer me.

But here he is on Freud, speaking like Gellner (but more sympathetically) of how Freud threaded the needle of modernity:

Psychoanalysis need not become the self-enclosed system which it so often is. But how do we avoid this?

Part of the answer is surely obtained by considerting the strain within Freud’s own writings between observation and explanation, between the material he amasses and the theoretical forms into which he cast his presentation of the material. The comparison with Newton misled not only his expositors but Freud himself. What Freud showed us were hitherto unnoticed facts, hitherto unrevealed motives, hitherto unrelated facets of our life. And in doing so his achievement broke all preconceived conceptual schemes–including his own. As a discoverer he perhaps resembles a Prsout or a Tolstoy rather than a Dalton or a  Pasteur. We could have learnt this from reading Freud himself; but the division among his heirs also reveals the fact clearly.

Yet both sets of heirs are legitimate. The sterility and perversity are as Freudian as the perceptive fertility of a Bettelheim or an Erikson. Freud, too, was a victim of the need to explain, of the need to be a Newton. The paradox of the history of psychoanalysis is that it is those analysts most intent on presenting their subject as a theoretical science who have transformed it into a religion, those most concerned with actual religious phenomena, such as Bettelheim and Erikson, who have preserved it as science. The achievement of Bettelheim and Erikson has been to extend our subjection to the phenomena themselves. But in so doing they have not diminished but increased its complexity.

Alasdair MacIntyre, “Psychoanalysis: The Future of an Illusion?” in Against the Self-Images of the Age (1971)

Well, this may be too kind to Bettelheim anad even Erikson, but MacIntyre certainly presents the kernel of Freud’s theory of the unconscious in a theoretically compelling fashion, as well as the problems it means to address.

What problems are these? They are problems of self-knowledge, or rather of lack of self-knowledge, of the nature of desire, and of the relationship of both to our actions. One of Freud’s insights, and here he had been anticipated by both Plato and Augustine, was that these problems are inseparable, that there is no adequate solution to any of them that does not involve a solution to the others.

Alasdair MacIntyre, The Unconscious (1958)

His 1958 critique of the unconscious holds up quite well 50 years on. He gives this pithy summation of the lack of explanatory power Freud gives us, as well as the inevitability of that lack of explanatory power in any understanding of the human. (Here he is clearly alluding to the scientific explanation vs. human understanding dichotomy proposed by Dilthey).

My thesis then is that in so far as Freud uses the concept of the unconscious as an explanatory concept, he fails, if not to justify it, at least to make clear its justification. He gives us causal explanations, certainly; but these can and apparently must stand or fall on their own feet without reference to it. He has a legitimate concept of unconscious mental activity, certainly; but this he uses to describe behaviour, not to explain it. This thesis, that Freud’s genius is notable in his descriptive work is not of course original. G. E. Moore has told us how Wittgenstein advanced it in his lectures in 1931–3. But it is important to understand how much of Freud’s work it affects….

But the grounds on which we ought to be dubious of speaking of the collective unconscious are ones which ought to make us dubious about speaking of the unconscious at all, except perhaps as a piece of metaphysics, an attempt at a more-than-scientific unification of concepts.

This suggestion, that in speaking of ‘the’ unconscious, we have left science for metaphysics is one that should not surprise us. At the beginning we saw that the attraction of the concept was that it seemed to promise a general formula by means of which a theoretical unification might be achieved in the study of human behaviour. It is now time to ask whether such a unification is in fact possible. The model for this project is drawn from physics which as the most advanced of the sciences tends also to be taken as the type to which others should approximate. To explain what human beings are and do in terms of a general theory is no doubt in some sense possible: the neurophysiologists will one day give us their full account, which will itself be reducible to a set of chemical and finally of physical explanations.

But will such an account give us what we want? It will state all the necessary conditions of human behaviour, but it will mention nothing of the specifically human. For this we need a different kind of account, the kind of portrayal that the novelist rather than the scientist gives us. In other words to portray the specifically human as human, and not as nervous system plus muscles, or as chain molecules, or as fundamental particles, is not to explain at all. Or at least it is to explain as Proust explains or as Tolstoy explains. Freud was certainly a scientist: but to remember this is to expand one’s conception of science. For his chief virtue resided in his power to see and to write so that we can see too. Or can we? He sowed also this doubt in our minds.

Alasdair MacIntyre, The Unconscious

In short, we are speaking of a metaphor (and of literature in general) far more than we are of a science.
