Man cannot survive except through his mind. He comes on earth unarmed. His brain is his only weapon. Animals obtain food by force. man had no claws, no fangs, no horns, no great strength of muscle. He must plant his food or hunt it. To plant, he needs a process of thought. To hunt, he needs weapons,and to make weapons - a process of thought. From this simplest necessity to the highest religious abstraction, from the wheel to the skyscraper, everything we are and we have comes from a single attribute of man -the function of his reasoning mind.

If [people] place such things as friendship and family ties above their own productive work, yes, then they are immoral. Friendship, family life and human relationships are not primary in a man's life. A man who places others first, above his own creative work, is an emotional parasite.

An inventor is a man who asks 'Why?' of the universe and lets nothing stand between the answer and his mind.

Capitalism was the only system in history where wealth was not acquired by looting, but by production, not by force, but by trade, the only system that stood for man's right to his own mind, to his work, to his life, to his happiness, to himself.

You love only those who deserve it.

I am not primarily an advocate of capitalism, but of egoism; I am not primarily an advocate of egoism, but of reason. If one recognizes the supremacy of reason and applies it consistently, all the rest follows.
