The unphilosophical majority among men are the ones most helplessly dependent on their era's dominant ideas. In times of crises these men need the guidance of some kind of theory; but, being unfamiliar with the field of ideas, they do not know that alternatives to the popular theories are possible. They know only what they have always been taught.-- Leonard Peikoff

To save the world is the simplest thing in the world. All one has to do is think.-- Leonard Peikoff

To those who oppose war, I ask: If not now, when? How many more corpses are necessary before this country should take action?-- Leonard Peikoff

[The proud man] does not demand of himself the impossible, but he does demand every ounce of the possible. He refuses to rest content with a defective soul, shrugging in self-deprecation 'That's me.' He knows that that 'me' was created, and is alterable, by him.-- Leonard Peikoff

Responsible parenthood involves decades devoted to the child's proper nurture. To sentence a woman to bear a child against her will is an unspeakable violation of her rights: her right to liberty (to the functions of her body), her right to the pursuit of happiness, and, sometimes, her right to life itself, even as a serf. Such a sentence represents the sacrifice of the actual to the potential, of a real human being to a piece of protoplasm, which has no life in the human sense of the term. It is sheer perversion of language for people who demand this sacrifice to call themselves 'right-to-lifers.'-- Leonard Peikoff
