The true finish is the work of time, and the use to which a thing is put. The elements are still polishing the pyramids.
Henry David ThoreauWhen you are starting away, leaving your more familiar fields, for a little adventure like a walk, you look at every object with a traveler's, or at least with historical, eyes; you pause on the first bridge, where an ordinary walk hardly commences, and begin to observe and moralize like a traveler. It is worth the while to see your native village thus sometimes, as if you were a traveler passing through it, commenting on your neighbors as strangers.
Henry David ThoreauWe have heard much about the poetry of mathematics, but very little of it has as yet been sung. The ancients had a juster notion of their poetic value than we. The most distinct and beautiful statements of any truth must take at last the mathematical form. We might so simplify the rules of moral philosophy, as well as of arithmetic, that one formula would express them both.
