"Religion is to mysticism what popularization is to science. What the mystic finds waiting for him, then, is a humanity which has been prepared to listen to his message by other mystics invisible and present in the religion which is actually taught. Indeed his mysticism itself is imbued with this religion, for such was its starting point. His theology will generally conform to that of the theologians. His intelligence and his imagination will use the teachings of the theologians to express in words what he experiences, and in material images what he sees spiritually. And this he can do easily, since theology has tapped that very current whose source is the mystical. Thus his mysticism is served by religion, against the day when religion becomes enriched by his mysticism. This explains the primary mission which he feels to be entrusted to him, that of an intensifier of religious faith."

“All the living hold together, and all yield to the same tremendous push. The animal takes its stand on the plant, man bestrides animality, and the whole of humanity, in space and in time, is one immense army galloping beside and before and behind each of us in an overwhelming charge able to beat down every resistance and clear the most formidable obstacles, perhaps even death.”

“The present contains nothing more than the past, and what is found in the effect was already in the cause.”

“Intuition is a method of feeling one's way intellectually into the inner heart of a thing to locate what is unique and inexpressible in it.”

“Men do not sufficiently realise that their future is in their own hands. Theirs is the task of determining first of all whether they want to go on living or not. Theirs is the responsibility, then, for deciding if they want merely to live, or intend to make just the extra effort required for fulfilling, even on their refractory planet, the essential function of the universe, which is a machine for the making of gods .”

“The prestige of the Nobel Prize is due to many causes, but in particular to its twofold idealistic and international character: idealistic in that it has been designed for works of lofty inspiration; international in that it is awarded after the production of different countries has been minutely studied and the intellectual balance sheet of the whole world has been drawn up. Free from all other considerations and ignoring any but intellectual values, the judges have deliberately taken their place in what the philosophers have called a community of the mind.”

“I cannot escape the objection that there is no state of mind, however simple, that does not change every moment.”
