Henry David ThoreauWe have heard much about the poetry of mathematics, but very little of it has yet been sung. The ancients had a juster notion of their poetic value than we.
Henry David ThoreauThe philanthropist too often surrounds mankind with the remembrance of his own cast- off griefs as an atmosphere, and calls it sympathy. We should impart our courage, and not our despair, our health and ease, and not our disease, and take care that this does not spread by contagion.
Henry David ThoreauIf a man believes and expects great things of himself, it makes no odds where you put him, or what you show him . . he will be surrounded by grandeur.
