Henri-Frederic Amiel

"The great artist is the simplifier.

"The man who has no refuge in himself, who lives, so to speak, in his front rooms, in the outer whirlwind of things and opinions, is not properly a personality at all. He floats with the current, who does not guide himself according to higher principles, who has no ideal, no convictions--such a man is a mere article of furniture--a thing moved, instead of a living and moving being--an echo, not a voice. The man who has no inner life is the slave of his surroundings, as the barometer is the obedient servant of the air at rest, and the weathercock the humble servant of the air in motion.

"The highest function of the teacher consists not so much in imparting knowledge as in stimulating the pupil in its love and pursuit. To know how to suggest is the art of teaching."
