• "My starting point is the fundamental initial fact that each one of us is perforce linked by all the material, organic, and psychic strands of his being to all that surrounds him." “Cosmic Life” (1916), in Writings in Time of War, trans. René Hague, Collins, 1968, p. 14.

• "We have gone a long way towards solving a problem when we are able to formulate it. (more science quotes)

• "Time and space are organically joined again so as to weave together the stuff of the universe."

• "Life is less certain than death."

• "We are faced with a harmonized collectivity of consciousnesses, a sort of superconciousness. The Earth is not only becoming covered by myriads of grains of thought but also becoming enclosed in a single thinking envelope, a single unanimous reflection."

• "The day will come when, after harnessing space, the winds, the tides, and gravitation, we shall harness for God the energies of Love. And, on that day, for the second time in the history of the world, man will have discovered fire." Toward the Future

• “A universal love is not only psychologically possible; it is the only complete and final way in which we are able to love.” ~ The Phenomenon of Man

• “Love is a sacred reserve of energy; it is like the blood of spiritual evolution.”

• “We are faced with a harmonized collectivity of consciousnesses to a sort of superconciousness. The earth not only becoming covered by myriads of grains of thought, but becoming enclosed in a single thinking envelope, a single unanimous reflection.”

• “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.” ~ The Heart of Matter (1950)

• “We are not human beings having a spiritual experience. We are spiritual beings having a human experience.” ~ The Phenomenon of Man

• “If there were no internal propensity to unite, even at a prodigiously rudimentary level — indeed in the molecule itself — it would be physically impossible for love to appear higher up, with us, in hominized form. ... Driven by the forces of love, the fragments of the world seek each other so that the world may come into being.”

• “Do not forget that the value and interest of life is not so much to do conspicuous things ... as to do ordinary things with the perception of their enormous value.”

• “The time has come to realise that an interpretation of the universe — even a positivist one — remains unsatisfying unless it covers the interior as well as the exterior of things; mind as well as matter. The true physics is that which will, one day, achieve the inclusion of man in his wholeness in a coherent picture of the world.”

• “Our duty, as men and women, is to proceed as if limits to our ability did not exist. We are collaborators in creation.”

• “In the final analysis, the questions of why bad things happen to good people transmutes itself into some very different questions, no longer asking why something happened, but asking how we will respond, what we intend to do now that it happened.”

• “The world, this palpable world, which we were wont to treat with the boredom and disrespect with which we habitually regard places with no sacred association for us, is in truth, a holy place, and we did not know it. Venite, adoremus.”

• “There is almost a sensual longing for communion with others who have a large vision. The immense fulfillment of the friendship between those engaged in furthering the evolution of consciousness has a quality impossible to describe.”

• “The whole life lies in the verb seeing.”

• “The most telling and profound way of describing the evolution of the universe would undoubtedly be to trace the evolution of love.”

• “And here I am thinking of those astonishing electronic machines (the starting-point and hope of the young science of cybernetics), by which our mental capacity to calculate and combine is reinforced and multiplied by the process and to a degree that herald as astonishing advances in this direction as those that optical science has already produced for our power of vision.”

• “In the spiritual life, as in all organic processes, everyone has their optimum and it is just as harmful to go beyond it as not to attain it.” ~ On Christian Asceticism, p. 100

• “Since once again, O Lord, in the steppes of Asia, I have no bread, no wine, no altar, I will raise myself above those symbols to the pure majesty of reality, and I will offer to you, I, your priest, upon the altar of the entire earth, the labor and the suffering of the world.
Receive, O Lord, in its totality the Host which creation, drawn by your magnetism, presents to you at the dawn of a new day. This bread, our effort, is in itself, I know, nothing but an immense disintegration. This wine, our anguish, as yet, alas! is only an evaporating beverage. But in the depths of this inchoate Mass, you have placed — I am certain, for I feel it — an irresistible and holy desire that moves us all, the impious as well as the faithful, to cry out: ‘O Lord, make us one!'”
