“Let each man say what he chooses; if because of this I am criticized by the ignorant, I shall not be chastised by the learned.”

“But until a person can say deeply and honestly, "I am what I am today because of the choices I made yesterday," that person cannot say, "I choose otherwise.”

“When I disagree with a rational man, I let reality be our final arbiter; if I am right, he will learn; if I am wrong, I will; one of us will win, but both will profit.”

“When a man says to me, 'Let us work together in the great cause you have undertaken, and let me be your companion and aid, for I admire you more than I have ever admired any other woman,' then I shall say, 'I am yours truly'; but he must ask me to be his equal, not his slave.”

“I know exactly what it takes to beat this man, but people say, 'Well, Ray, two years of inactivity, you'll be rusty.' No, no. He will eliminate the rust because he is what I want and I am what he wants. And boxing needs that kind of fight.”

“My heart leaps up when I behold
A rainbow in the sky:
So was it when my life began;
So is it now I am a man;
So be it when I shall grow old,
Or let me die!
The Child is father of the Man;
And I could wish my days to be
Bound each to each by natural piety.”

“Personally, I am a hedonistic reader; I have never read a book merely because it was ancient. I read books for the aesthetic emotions they offer me, and I ignore the commentaries and criticism.”

“The specialist serves as a striking concrete example of the species, making clear to us the radical nature of the novelty. For, previously, men could be divided simply into the learned and the ignorant, those more or less the one, and those more or less the other. But your specialist cannot be brought in under either of these two categories. He is not learned, for he is formally ignorant of all that does not enter into his speciality; but neither is he ignorant, because he is "a scientist," and "knows" very well his own tiny portion of the universe. We shall have to say that he is a learned ignoramus, which is a very serious matter, as it implies that he is a person who is ignorant, not in the fashion of the ignorant man, but with an the petulance of one who is learned in his own special line.”

“People say I am ruthless. I am not ruthless. And if I find the man who is calling me ruthless, I shall destroy him.”

“Each of us literally chooses, by his way of attending to things, what sort of universe he shall appear to himself to inhabit.”
