O hearts that break and give no sign Save whitening lip and fading tresses! - Oliver Wendell Holmes

Old Time, in whose banks we deposit our notes
Is a miser who always wants guineas for groats;
He keeps all his customers still in arrears
By lending them minutes and charging them years.

He must be a poor creature that does not often repeat himself. Imagine the author of the excellent piece of advice, "Know thyself," never alluding to that sentiment again during the course of a protracted existence! Why, the truths a man carries about with him are his tools; and do you think a carpenter is bound to use the same plane but once to smooth a knotty board with, or to hang up his hammer after it has driven its first nail? I shall never repeat a conversation, but an idea often. I shall use the same types when I like, but not commonly the same stereotypes. A thought is often original, though you have uttered it a hundred times. It has come to you over a new route, by a new and express train of associations.

Do you think I don't understand what my friend, the Professor, long ago called the hydrostatic paradox of controversy?
Don't know what it means? - Well, I will tell you. You know, that, if you had a bent tube, one arm of which was of the size of a pipe-stem, and the other big enough to hold the ocean, water would stand at the same height in one as in the other. Controversy equalizes fools and wise men in the same way, — and the fools know it.
