He wanted nothing, for the time being, except to understand .... Without advice, assistance or plan, he began reading an incongruous assortment of books; he would find some passage which he could not understand in one book, and he would get another on that subject .... There was no order in his reading; but there was order in what remained of it in his mind.
Ayn RandThe moral cannibalism of all hedonist and altruist doctrines lies in the premise that the happiness of one man necessitates the injury of another.
Ayn RandNo matter how vast your knowledge or how modest, it is your own mind that has to acquire it. It is only with your own knowledge that you can deal. It is only your own knowledge that you can claim to possess or ask others to consider. Your mind is your only judge of truth - and if others dissent from your verdict, reality is the court of final appeal. Nothing but a man's mind can perform that complex, delicate, crucial process of identification which is thinking. Nothing can direct the process but his own judgment. Nothing can direct his judgment but his moral integrity.
