“Man has been called a rational being, but rationality is a matter of choice — and the alternative his nature offers him is: rational being or suicidal animal. Man has to be man — by choice; he has to hold his life as a value — by choice; he has to learn to sustain it — by choice; he has to discover the values it requires and practice his virtues — by choice.
A code of values accepted by choice is a code of morality.”
― Ayn Rand, Atlas Shrugged

“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.”
― Ayn Rand, Atlas Shrugged

“Reason is the faculty that perceives, identifies and integrates the material provided by his senses. The task of his senses is to give him the evidence of existence, but the task of identifying it belongs to his reason; his senses tell him only that something is, but what it is must be learned by his mind.”
― Ayn Rand, Atlas Shrugged

“I disapprove of what you say, but I will defend to the death your right to say it”
