“Human beings are the only ones in nature who are aware that they will die. For that reason and only for that reason, I have a profound respect for the human race, and I believe that its future is going to be much better than its present. Even knowing that their days are numbered and that everything will end when they least expect it, people make of their lives a battle that is worthy of a being with eternal life. What people regard as vanity-leaving great works, having children, acting in such a way as to prevent one's name from being forgotten- I regard as the highest expression of human dignity.”

“Since the day I was born, I’ve spent my time being a human being, and I regard this as a good decision. But not a great one.”

“...human beings as a species have never failed to find reasons to regard one another with fear and loathing and thus to offer violence to one another.”

“I believe in recognizing every human being as a human being--neither white, black, brown, or red; and when you are dealing with humanity as a family there's no question of integration or intermarriage. It's just one human being marrying another human being or one human being living around and with another human being.”

“I am a very bad scientist. I will do anything to make a human being feel better, even if it's unscientific. No scientist worthy of the name could say such a thing.”
