“ Schizophrenia is just a catch-all term for forms of mental behaviour that we don’t understand. In the nineteenth century there was a term, melancholia, which we would now call bipolar depression… but all forms of sadness, unhappiness, maladaptation, were poured into this label melancholia… Now, schizophrenia is a similar thing… A book about schizophrenia [says that] the typical schizophrenic lives in a world of twilight imagining. Marginal to his society, incapable of holding a regular job, these people live on the fringes content to drift in their own self-created value system. I said, that’s it! That’s it! Now I understand! ”
