Nobody has ever given a reason why men should be their brother's keepers.

The difference between animals and humans is that animals change themselves for the environment, but humans change the environment for themselves.

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.

Self-sacrifice? But it is precisely the self that cannot and must not be sacrificed.

Love should be treated like a business deal, but every business deal has its own terms and its own currency. And in love, the currency is virtue. You love people not for what you do for them or what they do for you. You love them for the values, the virtues, which they have achieved in their own character.

To love money is to know and love the fact that money is the creation of the best power within you, and your passkey to trade your effort for the effort of the best among men.

My philosophy, in essence, is the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute.
