"Revenge is barren of itself: it is the dreadful food it feeds on; its delight is murder, and its end..." — Friedrich Schiller

Opposition always inflames the enthusiast, never converts him.

He who considers too much will perform little.

It hinders the creative work of the mind if the intellect examines too closely the ideas as they pour in.

Of all the possessions of this life fame is the noblest; when the body has sunk into the dust the great name still lives.
