“The Ego is the great veiled mystery of the world... I believe in it and in its eternal, immutable form. Its path is, in some strange and peculiar manner, our path. And for this reason I am immersed in the phenomenon of the Individual, the so-called whole Individual, and I try in every way to explain and present it. What are you? What am I? Those are the questions that constantly persecute and torment me and perhaps also play some part in my art.”

As quoted in The Lives of the Great Composers (1997) by Harold C. Schonberg, p. 464

Context: So please don't think that I am renouncing anything, I am reasonably faithful in my unfaithfulness and though I have changed, I am the same, and what preys on my mind is simply this one question: what am I good for, could I not be of service or use in some way, how can I become more knowledgeable and study some subject or other in depth? That is what keeps preying on my mind, you see, and then one feels imprisoned by poverty, barred from taking part in this or that project and all sorts of necessities are out of one's reach. As a result one cannot rid oneself of melancholy, one feels emptiness where there might have been friendship and sublime and genuine affection, and one feels dreadful disappointment gnawing at one's spiritual energy, fate seems to stand in the way of affection or one feels a wave of disgust welling up inside. And then one says “How long, my God!”

Context: What I am searching for... is some formula that would combine individual initiative with universal values, and that combination would give us a truly organic form. Form, which we discover in nature by analysis, is obstinately mathematical in its manifestations—which is to say that creation in art requires thought and deliberation. But this is not to say that form can be reduced to a formula. In every work of art it must be re-created, but that too is true of every work of nature. Art differs from nature not in its organic form, but in its human origins: in the fact that it is not God or a machine that makes a work of art, but an individual with his instincts and intuitions, with his sensibility and his mind, searching relentlessly for the perfection that is neither in mind nor in nature, but in the unknown. I do not mean this in an other-worldly sense, only that the form of the flower is unknown to the seed.
