Context: “How then?” Taran asked. “Could The Book of Three deceive you?”
“No, it could not.” Dallben said. “The book is thus called because it tells all three parts of our lives: the past, the present, and the future. But it could as well be called a book of ‘if.’ If you had failed at your tasks; if you had followed an evil path; if you had been slain; if you had not chosen as you did — a thousand ‘ifs,’ my boy, and many times a thousand. The Book of Three can say no more than ‘if’ until at the end, of all things that might have been, one alone becomes what really is. For the deeds of a man, not the words of a prophecy, are what shape his destiny.”
“This tendency might be phrased as the desire to become more and more what one is, to become everything that one is capable of becoming.”

Context: A musician must make music, an artist must paint, a poet must write, if he is to be ultimately at peace with himself. What a man can be, he must be. This need we may call self-actualization. This term, first coined by Kurt Goldstein, is being used in this paper in a much more specific and limited fashion. It refers to the desire for self-fulfillment, namely, to the tendency for him to become actualized in what he is potentially. This tendency might be phrased as the desire to become more and more what one is, to become everything that one is capable of becoming.

Ich bin nicht nur überzeugt, dass das, was ich sage, falsch ist, sondern auch das, was man dagegen sagen wird. Trotzdem muss man anfangen, davon zu reden. Die Wahrheit liegt bei einem solchen Gegenstand nicht in der Mitte, sondern rundherum wie ein Sack, der mit jeder neuen Meinung, die man hineinstopft, seine Form ändert, aber immer fester wird!
