Error is the force that welds men together; truth is communicated to men only by deeds of truth.

The truth is found when men are free to pursue it.

Man has much power of discourse which for the most part is vain and false; animals have but little, but it is useful and true, and a small truth is better than a great lie.

Men occasionally stumble over the truth, but most of them pick themselves up and hurry off as if nothing ever happened.

Convictions are more dangerous foes of truth than lies.

On the mountains of truth you can never climb in vain: either you will reach a point higher up today, or you will be training your powers so that you will be able to climb higher tomorrow.
