Louis Sass disputes that schizophrenia can be understood successfully according to the hitherto dominant models--for much of what schizophrenics say and do is neither regressive (as psychoanalysis claims) nor just faulty reasoning (as "cognitivists" claim). Sass argues instead that schizophrenics frequently exhibit hyper-rationality, much as philosophers do. He holds that schizophrenic language can after all be interpreted--if we hear it as Wittgenstein hears solipsistic language. I counter first that broadly Winchian considerations undermine both the hermeneutic conception of interpreting other humans (...) in general and Sass's hope of interpreting schizophrenics in particular. I then go on to argue that even if these Winchian considerations are not accepted, Sass in any case doesn't take sufficiently seriously Wittgenstein's use of nonsense as a term of criticism. Solipsism is not something we can understand so as to be able to understand analogically the schizophrenic's "world"--for there is no such thing as understanding it. Solipsism is nonsense, is nothing--there is no "world" there, in solipsists (as I show by reference to Cora Diamond's reading of Wittgenstein). Nor in any actually analogous cases of schizophrenia. Their "alienness" is the alienness of nothingness; roughly, of the fantasy of "logically alien thought". (shrink)

In the formative years of psychiatry Freud, Bleuler, and Jaspers all studied Daniel Paul Schreber's Memoirs of My Nervous Illness as a model of psychotic thought. Sass provides a nuanced interpretation of Schreber's Memoirs in the context of Wittgenstein's analysis of philosophical solipsism. A dauntless critic of the illusions of philosophy, Wittgenstein likened the speculative excesses of traditional metaphysics to mental illness. Sass observes that many of the "intellectual diseases" that Wittgenstein discerned - diseases involving detachment from social existence and (...) practical concerns, and exaggerated processes of abstraction and self-consciousness - have striking affinities with the symptoms of schizophrenia. Like the philosophical solipsist, the schizophrenic may define his or her own consciousness as the center of the universe - and may experience his or her delusional world as a product of that same consciousness.
