“In madness, I thought I was the most important person in the world.”

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 have made the most important discovery of my career, the most important discovery of my life.

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

However I am still making the effort and it is conceivable that with the gap period of about 25 years of partially deluded thinking providing a sort of vacation my situation may be atypical.

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

Classes will dull your mind, destroy the potential for authentic creativity.

Gradually I began to intellectually reject some of the delusionally influenced lines of thinking which had been characteristic of my orientation.

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.

Statistically, it would seem improbable that any mathematician or scientist, at the age of 66, would be able through continued research efforts, to add much to his or her previous achievements.

Nowadays we can do computer experiments using Mathematica, and even solve a system of 42 equations. This offers another route to knowledge, rather than mere ideas.

The man who owns up to arthritis in a beri-beri year is as lonely as a woman in a last month’s dress.

But the Princeton fellowship was somewhat more generous, since I had not actually won the Putnam competition… Thus Princeton became the choice for my graduate study location.

I would become a therapist and a leader in terms of mental illness. But I’m not in the position.

As you will find in multivariable calculus, there is often a number of solutions for any given problem.

People are always selling the idea that people with mental illness are suffering.

This began, most recognizably, with the rejection of politically-oriented thinking as essentially a hopeless waste of intellectual effort.
