“Intellectual and moral growth is no less indispensable than material improvement. Knowledge is a viaticum. Though is a prime necessity; truth is nourishment, like wheat. A reasoning faculty, deprived of knowledge and wisdom, pines away. We should feel the same pity for minds that do not eat as for stomachs. If there be anything sadder than a body perishing for want of bread, it is a mind dying of hunger for lack of light. All progress tends toward the solution. Some day, people will be amazed. As the human race ascends, the deepest layers will naturally emerge from the zone of distress. The effacement of wretchedness will be effected by a simple elevation level.”

“As with stomachs, we should pity minds that do not eat.”

“You were right to come to see a dying man. It is right that these moments should have witnesses. Everyone has his dream; I would like to live till dawn, but I know I have less than three hours left.

But too much submerges and drowns. Woe to the intellectual worker who allows himself to lapse wholly from positive thinking into day-dreaming. He thinks he can easily change back, and tells himself that it is all one. He is wrong! Thought is the work of the intellect, reverie is its self-indulgence. To substitute day-dreaming for thought is to confuse poison with a source of nourishment.”

“A phenomenon often seen. A sceptic adhering to a believer; that is as simple as the law of the complementary colours. What we lack attracts us. Nobody loves the light like the blind man...”
