Rationality is the recognition of the fact that existence exists, that nothing can alter the truth and nothing can take precedence over that act of perceiving it, which is thinking—that the mind is one’s only judge of values and one’s only guide of action—that reason is an absolute that permits no compromise—that a concession to the irrational invalidates one’s consciousness and turns it from the task of perceiving to the task of faking reality—that the alleged short-cut to knowledge, which is faith, is only a short-circuit destroying the mind—that the acceptance of a mystical invention is a wish for the annihilation of existence and, properly, annihilates one’s consciousness.
