“Louis Sass has demonstrated, by his comparisons of Wittgenstein’s critique of philosophy with Daniel Paul Schreber’s detailed accounts of his own psychotic illness (Schreber was the subject of Freud’s only study of schizophrenia), that there are extensive similarities between schizophrenia and the state of mind that is brought about when one makes a conscious effort to distance oneself from one’s surroundings, refrain from normal action and interaction with them, suspend one’s normal assumptions and feelings about them and subject them to a detached scrutiny – an exercise which in the non-mentally ill is normally confined to philosophers.”
