"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."
