“I owe the best of myself to geology, but everything it has taught me tends to turn me away from dead things.”

Evolution is a light illuminating all facts, a curve that all lines must follow.

For me, the real earth is that chosen part of the universe, still almost universally dispersed and in course of gradual segregation, but which is little by little taking on body and form in Christ.

I am not enough of a mathematician to be able to judge either the well-foundedness or the limits of relativity in physics.

What is imponderable in the world is greater than what we can handle.

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.

Driven by the forces of love, the fragments of the world seek each other so that the world may come to being.

The only one which can embrace the past and future of evolution and so contemplate, measure and fulfil them.

The profoundly ‘atomic’ character of the universe is visible in everyday experience, in raindrops and grains of sand, in the hosts of the living, and the multitude of stars; even in the ashes of the dead.

Religion and science are the two conjugated faces or phases of one and the same complete act of knowledge .

I feel a distaste for hunting, first because of a kind of Buddhist respect for the unity and sacredness of all life, and also because the pursuit of a hare or chamois strikes me as a kind of ‘escape of energy,’ that is, the expenditure of our effort in an illusory end, one devoid of profit.

To our critical eyes, the threads of which the past is woven are, by nature, endless and indivisible. Scientifically speaking, we cannot grasp the absolute beginning of anything: everything extends backwards to be prolonged by something else.

Religion, born of the earth’s need for the disclosing of a god, is related to and co-extensive with not the individual man, but the whole of mankind.

Everyone, no doubt, remains first and foremost a man of his own country and continues to draw from it his motive force.

Death surrenders us totally to God: it makes us enter into him; we must, in return, surrender ourselves to death with absolute love and self-abandonment since.

The problem of evil, that is to say the reconciling of our failures, even the purely physical ones, with creative goodness and creative power, will always remain one of the most disturbing mysteries of the universe for both our hearts and our minds.
