Blessed be you, mighty matter, irresistible march of evolution, reality ever newborn; you who, by constantly shattering our mental categories, force us to go ever further and further in our pursuit of the truth.

Joy is the infallible sign of the presence of God.

Matter is spirit moving slowly enough to be seen.

The age of nations has passed. Now, unless we wish to perish, we must shake off our old prejudices and build the Earth. The more scientifically I regard the world, the less can I see any possible biological future for it except in the active consciousness of its unity.

The day is not far distant when humanity will realize that biologically it is faced with a choice between suicide and adoration.

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

We have reached a crossroads in human evolution where the only road which leads forward is towards a common passion. . . To continue to place our hopes in a social order achieved by external violence would simply amount to our giving up all hope of carrying the Spirit of the Earth to its limits.
