Is evolution a theory, a system, or a hypothesis? It is much more it is a general postulate to which all theories, all hypotheses, all systems must henceforward bow and which they must satisfy in order to be thinkable and true. Evolution is a light which illuminates all facts, a trajectory which all lines of thought must follow this is what evolution is.

The only way forward is in the direction of a common passion, for nothing in the universe can ultimately resist the cumulative ardor of the collective soul.

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.

The human person is the sum total of a 15 billion year chain of unbroken evolution now thinking about itself

Each element of the cosmos is positively woven from all the others...The universe holds together, and only one way of considering it is really possible, that is, to take it as a whole, in one piece.

By means of all created things, without excaption, the divine assails us, penetrates us, and molds us. We imagined it as distant and inaccessible, when in fact we live steeped in its burning layers

We see not only thought as participating in evolution as an anomaly or as an epiphenomenon; but evolution as so reducible to and identifiable with a progress towards thought that the movement of our souls expresses and measures the very stages of progress of evolution itself. Man discovers that he is nothing else than evolution become conscious of itself.
