At the heart of our universe, each soul exists for God, in our Lord.

The future belongs to those who give the next generation reason for hope.

Your creatures can come into being only, like shoot from stem, as part of an endlessly renewed process of evolution.

Mankind is still embryonic ... [man is] the bud from which something more complicated and more centered than man himself should emerge.

We may, perhaps, imagine that the creation was finished long ago. But that would be quite wrong. It continues still more magnificently, and at the highest levels of the world.

From an evolutionary point of view, man has stopped moving, if he ever did move.

The stars are laboratories in which the evolution of matter proceeds in the direction of large molecules.
