Pierre Teilhard de Chardin

Everywhere on Earth, at this moment, in the new spiritual atmosphere created by the appearance of the idea of evolution, there float, in a state of extreme mutual sensitivity, love of God and faith in the world: the two essential components of the Ultra-human.

Love is a sacred reserve of energy; it is like the blood of spiritual evolution.

Someday, after mastering the winds, the waves, the tides and gravity, we shall harness for God the energies of love, and then, for a second time in the history of the world, man will have discovered fire.

Have you ever thought how humiliating and distressing it was to be placed upon a sphere? For friendship it is a boon never to be able to be further apart than the antipodes. But suppose that you are leaving together to go on and on; it is impossible. To go beyond a certain point is to return to where you began.

The world is round so that friendship may encircle it.

The most satisfying thing in life is to have been able to give a large part of one's self to others.
