Famous quotes containing the word psychology:
“A writer must always try to have a philosophy and he should also have a psychology and a philology and many other things. Without a philosophy and a psychology and all these various other things he is not really worthy of being called a writer. I agree with Kant and Schopenhauer and Plato and Spinoza and that is quite enough to be called a philosophy. But then of course a philosophy is not the same thing as a style.”
—Gertrude Stein (1874–1946)
