“Wonderful nature has a double meaning, which dazzles great minds and blinds uncultivated souls. When man is ignorant, when the desert is filled with visions, the darkness of solitude is added to the darkness of intelligence; hence, in man, the possibilities of perdition”

“A blind man's world is bounded by the limits of his touch; an ignorant man's world by the limits of his knowledge: a great man's world by the limits of his vision.”

“There is a master way with words which is not learned but is instead developed: a deaf man develops exceptional vision, a blind man exceptional hearing, a silent man, when given a piece of paper...”

“... when someone sees a soul disturbed and unable to see something, he won't laugh mindlessly, but he'll take into consideration whether it has come from a brighter life and is dimmed through not having yet become accustomed to the dark or whether it has come from greater ignorance into greater light and is dazzled by the increased brillance.”

“Rationality is man's basic virtue, the source of all his other virtues. Man's basic vice, the source of all evils, is the act of unfocussing his mind, the suspension of his conciousness, which is not blindness, but the refusal to see, not ignorance, but the refusal to know. Irrationality is the rejection of man's means of survival and therefore, a commitment to a course of blind destruction; that is anti-mind, anti-life.”

“The age of great men, when a single mind of intelligence and vision might change the destiny of the world, was long gone.”
