Aristotle may be regarded as the cultural barometer of Western history. Whenever his influence dominated the scene, it paved the way for one of history's brilliant eras; whenever it fell, so did mankind.

Money is the barometer of a society's virtue. Ayn Ran

Ayn Rand
To arrive at a contradiction is to confess an error in one's thinking; to maintain a contradiction is to abdicate one's mind and to evict oneself from the realm of reality.
Ayn Rand

It was the greatest sensation of existence: not to trust but to know.

Ayn Rand
A man of independent judgment is a man of profound self-esteem.
Ayn Rand

Man—every man—is an end in himself, not a means to the ends of others; he must live for his own sake, neither sacrificing himself to others nor sacrificing others to himself; he must work for his rational self-interest, with the achievement of his own happiness as the highest moral purpose of his life.

Ayn Rand
Man is a being with free will; therefore, each man is potentially good or evil, and it's up to him and only him (through his reasoning mind) to decide which he wants to be.
Ayn Rand

If a life could have a theme song - and I believe every worthwhile one has - mine is a religion, an obsession, a mania or all of these expressed in one word - individualism. I was born with that obsession, and I've never seen and do not know now a cause more worthy, more misunderstood, more seemingly hopeless and tragically needed.

Ayn Rand
Money is the root of all good.
Ayn Rand

When you have established that one alternative is good and the other is evil, there is no justification for the choice of a mixture. There is no justification ever for choosing any part of what you know to be evil.

Ayn Rand
If it were true that men could achieve their good by means of turning some men into sacrificial animals, and . . . if I were asked to serve the interests of society apart from, above and against my own I would refuse. . . . I would fight in the full confidence of the justice of my battle and of a living being's right to exist.
