"Is evolution a theory, a system or a hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true. Evolution is a light illuminating all facts, a curve that all lines must follow."

“I am far from denying the destructive and disintegrating forces of passion. I will go so far as to agree that apart from the reproductive function, men have hitherto used love, on the whole, as an instrument of self-corruption and intoxication. But what do these excesses prove? Because fire consumes and electricity can kill are we to stop using them? The feminine is the most formidable of the forces of matter. True enough. "Very well, then," say the moralists, "we must avoid it." "Not at all," I reply, "we take hold of it." In every domain of the real "danger" is a sign of power. Only a mountain can create a terrifying drop. The customary education of the Christian conscience tends to make us confuse tutiorism with prudence, safety with truth. Avoiding the risk of transgression has become more important to us than carrying a difficult position for God. And it is this that is killing us. "The more dangerous a thing, the more is its conquest ordained by life": it is from that conviction that the modern world has emerged; and from that our religion, too, must be reborn.”

“We are like soldiers who fall during the assault which leads to peace.”

“We only have to look around us to see how complexity and psychic temperature are still rising: and rising no longer on the scale of the individual but now on that of the planet. This indication is so familiar to us that we cannot but recognize the objective, experiential, reality of a transformation of the planet as a whole.”

“By virtue of creation, and still more the incarnation, nothing here is profane for those who know how to see.”

“In its most general form and from the point of view of physics, love is the internal, affectively apprehended, aspect of the affinity which links and draws together the elements of the world, centre to centre. This is how it has been understood by the great philosophers from Plato, the poet, to Nicolas of Cusa and other representatives of frigid scholasticism. Once this definition has been accepted, it gives rise to a series of important consequences. Love is power of producing inter-centric relationship. It is present, therefore , in all the natural centres, living and pre-living, which make up the world; and it represents, too, the most profound, most direct, and most creative form of inter-action that it is possible to conceive between those centres. Love, in fact, is the expression and the agent of universal synthesis.”

“God is inexhaustibly attainable in the totality of our action.”
