Living in a society, instead of on a desert island, does not relieve a man of the responsibility of supporting his own life.

Altruism does not mean mere kindness or generosity, but the sacrifice of the best among men to the worst, the sacrifice of virtues to flaws, of ability to incompetence, of progress to stagnation-and the subordinating of all life and of all values to the claims of anyone's suffering.

The word 'We' is as lime poured over men, which sets and hardens to stone, and crushes all beneath it, and that which is white and that which is black are lost equally in the grey of it. It is the word by which the depraved steal the virtue of the good, by which the weak steal the might of the strong, by which the fools steal the wisdom of the sages.

The great creators - the thinkers, the artists, the scientists, the inventors - stood alone against the men of their time. Every great new thought was opposed. Every great new invention was denounced. The first motor was considered foolish. The airplane was considered impossible... But the men of unborrowed vision went ahead. They fought, they suffered and they paid. But they won.
