I would not dare to say that there is a direct relation between mathematics and madness, but there is no doubt that great mathematicians suffer from maniacal characteristics, delirium and symptoms of schizophrenia.

I seem to be thinking rationally again in the style that is characteristic of scientists. However this is not entirely a matter of joy as if someone returned from physical disability to good physical health.

To some extent, people who are insane are nonconformists, and society and their family wish they would live what appear to be useful lives.

Though I had success in my research both when I was mad and when I was not, eventually I felt that my work would be better respected if I thought and acted like a 'normal' person.

People are always selling the idea that people with mental illness are suffering. I think madness can be an escape. If things are not so good, you maybe want to imagine something better.

There are things that tend to moderate with age. Schizophrenia is somewhat like that.

Rationality of thought imposes a limit on a person's concept of his relation to the cosmos.
