What is it that I wish to convey?...I wish to convey something immaterial and I have to use material means for it. I have to convey something which is inexpressible and I have to use expression. I have to convey, perhaps, something unconscious and I have to use conscious means. I know in advance that I shall not succeed and cannot succeed, and therefore all I can do is to get nearer and nearer in some asymptotic approach; I do my best, but it is an agonizing struggle in which, if I am…any kind of self-conscious thinker, I am engaged for the whole of my life.
