I have myself been gravely mad, and I can value with greater cause than most the advantages of being sane.

... the path I took led to adventures out of the realm of any sober scientist.

In normal life at times of strong emotion, and especially at moments of great fear, we find that we are more keenly aware than usual of the external details of our world ... In psychotic states, where the fate of the whole universe may be at stake, awareness of material objects and of trivial events can be heightened to an extent that is outside the range of sane experience.

Psychosis opens wide the doors to a world that most people know only through the undercurrent of their dreams.

... the individual is alone. That is the central feature when we penetrate insanity. Not that the world is less with us, but that another world pervades it too, and we, seeing and experiencing life upon a different plane, are cut off from communication with the sane around us.

... the scientific trilogy: observation, hypothesis, experiment.

... sex is one of the great wonders and glories of life.

Eventually I reached a pitch where I might even have been suicidal, except that I feared death more than I feared myself.
