“Life, in a body whose order and state of affairs can make it manifest, is assuredly, as I have said, a real power that gives rise to numerous phenomena. This power has, however, neither goal nor intention. It can do only what it does; it is only a set of acting causes, not a particular being. I was the first to establish this truth at a time when life was still thought to be a principle, an archeia, a being of some sort.”

Spiritualism and the Christian Faith (1918)

This being the case, it is evident that the onus probandi [burden of proof] ought to lie with those who are willing to establish such an hypothesis, for it does not appear that Nature is in the habit of using one and the same mechanism with any two of our senses. Witness the vibration of air that makes sound, the effluvia that occasion smells, the particles that produce taste, the resistance or repulsive powers that affect the touch—all these are evidently suited to their respective organs of sense.

II. That God is unchanging, unbegotten, eternal, incorporeal, and not in space.
Variant translation:
The essences of the gods are neither generated; for eternal natures are without generation; and those beings are eternal who possess a first power, and are naturally void of passivity. Nor are their essences composed from bodies; for even the powers of bodies are incorporeal: nor are they comprehended in place; for this is the property of bodies: nor are they separated from the first cause, or from each other; in the same manner as intellections are not separated from intellect, nor sciences from the soul.
II. That a God is immutable, without Generation, eternal, incorporeal, and has no Subsistence in Place, as translated by Thomas Taylor

Man's Search for Meaning (1946; 1959; 1984)
Context: A thought transfixed me: for the first time in my life I saw the truth as it is set into song by so many poets, proclaimed as the final wisdom by so many thinkers. The truth — that love is the ultimate and the highest goal to which man can aspire. Then I grasped the meaning of the greatest secret that human poetry and human thought and belief have to impart: The salvation of man is through love and in love. … For the first time in my life I was able to understand the meaning of the words, "The angels are lost in perpetual contemplation of an infinite glory."
