“I can say this. I believe that the human mind, or even the mind of a cat, is more interesting in its complexity than an entire galaxy if it is devoid of life.”

“The complexity of the world is not revealed by its simplification in human mind.”

“I have to speak my mind. Because what is in my mind is always more interesting than what is happening in the world outside my mind.”

“I can remember how when I was young I believed death to be a phenomenon of the body; now I know it to be merely a function of the mind — and that of the minds who suffer the bereavement. The nihilists say it is the end; the fundamentalists, the beginning; when in reality it is no more than a single tenant or family moving out of a tenement or a town.”

“Humans are great lovers of consistency, and it annoys us that cats have different rules. Even if a cat is willing to give up her life for you, that does not mean that she is willing to change her mind at your request.”

“The psychology of a complex mind must differ almost as much from that of a simple, mechanized mind as its psychology would from ours; because something that must underlie and perhaps be even greater than sex is involved.”

“Either mathematics is too big for the human mind, or the human mind is more than a machine.”

“To my mind the life of a lamb is no less precious than that of a human being. I should be unwilling to take the life of a lamb for the sake of the human body. I hold that, the more helpless a creature, the more entitled it is to protection by man from the cruelty of man.”

“When my mind is operating at its peak, it should depress me to think that this is the best I can do, because it's not very good at all. When my mind is operating normally, I should be even more depressed.”

“A cat is more intelligent than people believe, and can be taught any crime.”
