And yet I must prevent my critical powers from destroying my creativeness. I know well enough that every word I utter carries with it something of myself—of my special and unique self with its particular history and its own particular world. Even when I deal with empirical data, I am necessarily speaking about myself. But it is only by accepting this as inevitable that I can serve the cause of man’s knowledge of man—the cause which Freud also wished to serve, and which, in spite of everything, he has served. Knowledge rests not upon truth alone, but upon error also.
