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.
