People create their own questions because they are afraid to look straight. All you have to do is look straight and see the road, and when you see it, don't sit looking at it - walk.

And questions give us no rest. We know not why our curse makes us seek we know not what, ever and ever. But we cannot resist it.

We must know that we may know.

In proportion to the mental energy he spent, the man who creates a new invention receives but a small percentage of his value in terms of material payment, no matter what fortune he makes, no matter what millions he earns. But the man who works as a janitor in the factory producing that invention, receives an enormous payment in proportion to the mental effort that his job requires of him. And the same is true of all men between, on all levels of ambition and ability.

Collectivism holds that the individual has no rights, that his life and work belong to the group (to "society," to the tribe, the state, the nation) and that the group may sacrifice him at its own whim to its own interests. The only way to implement a doctrine of that kind is by means of brute force - and statism has always been the poltical corollary of collectivism.

A good quotation must be a complete entity. It must be like a headline - sharp, clear, whole.
