An honest man is one who knows that he can't consume more than he has produced.

The most depraved type of human being ... (is) the man without a purpose.

Independence is the recognition of the fact that yours is the responsibility of judgement and nothing can help you escape it - that no substitute can do your thinking, as no pinch-hitter can live your life.

To achieve, you need thought

If capitalism had never existed, any honest humanitarian should have been struggling to invent it. But when you see men struggling to evade its existence, to misrepresent its nature, and to destroy its last remnants - you maybe sure that whatever their motives, love of man is not one of them.

Face a challenge and find joy in the capacity to meet it.

The necessary consequence of man's right to life is his right to self-defense. In a civilized society, force may be used only in retaliation and only against those who initiate its use. All the reasons which make the initiation of physical force an evil, make the retaliatory use of physical force a moral imperative. If some "pacifist" society renounced the retaliatory use of force, it would be left helplessly at the mercy of the first thug who decided to be immoral. Such a society would achieve the opposite of its intention: instead of abolishing evil, it would encourage and reward it.
