Miguel de Unamuno

The greatest height of heroism to which an individual, like a people, can attain is to know how to face ridicule.

We never know, believe me, when we have succeeded best.

We need God, not in order to understand the why, but in order to feel and sustain the ultimate wherefore, to give a meaning to the universe.

Cure yourself of the affliction of caring how you appear to others. Concern yourself only with how you appear before God, concern yourself only with the idea that God may have of you.

The skeptic does not mean him who doubts, but him who investigates or researches, as opposed to him who asserts and thinks that he has found.

A lot of good arguments are spoiled by some fool who knows what he is talking about.
