"A man without passion, the pledge of great loftiness of spirit which by its very superiority redeems a man from the yoke of vagrant and vulgar externals. There is no greater mastery than the mastery of self, and its passions, for it amounts to the triumph of free will, but even where passion overcomes the individual, it must not dare to touch his office, especially if it be a high one; this is the best way to spare yourself grief, and yet the shortest way to a good reputation."
"Think, and most about that which is most important: all the fools get lost because they do not think: they never see the half of things, and knowing neither their loss, nor their profit, they make small effort in either direction. Some make much of what is of little importance, or little of what is of much importance, always judging wrong. Most do not lose their heads because they have none. There are matters which should be considered with every faculty, and then be treasured in the depths of the mind. An intelligent man thinks about everything, though with discrimination, digging deepest where there are prospect and treasure; knowing always that more lies buried than he knows; but such means does what is apprehended become what is comprehended".
