I know but one freedom and that is the freedom of the mind.

Water, thou hast no taste, no color, no odor; canst not be defined, art relished while ever mysterious. Not necessary to life, but rather life itself, thou fillest us with a gratification that exceeds the delight of the senses.

That's the way they are. You must not hold it against them. Children should be very understanding of grown-ups.

Although human life is priceless, we always act as if something had an even greater price than life... but what is that something?

There is a cheap literature that speaks to us of the need of escape. It is true that when we travel we are in search of distance. But distance is not to be found. It melts away. And escape has never led anywhere. The moment a man finds that he must play the races, go the Arctic, or make war in order to feel himself alive, that man has begin to spin the strands that bind him to other men and to the world. But what wretched strands! A civilization that is really strong fills man to the brim, though he never stir. What are we worth when motionless, is the question.

Mad is the man who is forever gritting his teeth against that granite block, complete and changeless, of the past.

As for the future, your task is not to foresee it, but to enable it.
