Consider the reasons which make us certain that we are right, but not the fact that we are certain. If you are not convinced, ignore our certainty. Don't be tempted to substitute our judgment for your own.
Ayn RandLiving in a society, instead of on a desert island, does not relieve a man of the responsibility of supporting his own life.
Ayn RandWe cannot fight against collectivism, unless we fight against its moral base: altruism. We cannot fight against altruism, unless we fight against its epistemological base: irrationalism. We cannot fight against anything, unless we fight for something--and what we must fight for is the supremacy of reason and a view of man as a rational being.
