It is a wise thing to be polite; consequently, it is a stupid thing to be rude. To make enemies by unnecessary and willful incivility, is just as insane a proceeding as to set your house on fire. For politeness is like a counter--an avowedly false coin, with which it is foolish to be stingy.
Arthur SchopenhauerA 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.
