A man may call to mind the face of his friend, but not his own. Here, then, is an initial difficulty in the way of applying the maxim, Know Thyself.

The inexpressible depth of music, so easy to understand and yet so inexplicable, is due to the fact that it reproduces all the emotions of our innermost being, but entirely without reality and remote from its pain… Music expresses only the quintessence of life and its events, never these themselves.

A man of intellect is like an artist who gives a concert without any help from anyone else, playing on a single instrument--a piano, say, which is a little orchestra in itself. Such a man is a little world in himself; and the effect produced by various instruments together, he produces single-handed, in the unity of his own consciousness. Like the piano, he has no place in a symphony; he is a soloist and performs by himself--in soli tude, it may be; or if in the company with other instruments, only as principal; or for setting the tone, as in singing.
