“It seemed as impossible to conceive of Auschwitz with God as to conceive of Auschwitz without God. Therefore, everything had to be reassessed because everything had changed. With one stroke, mankind's achievements seemed to have been erased. Was Auschwitz a consequence or an aberration of "civilization"? All we know is that Auschwitz called that civilization into question as it called into question everything that had preceded Auschwitz. Scientific abstraction, social and economic contention, nationalism, xenophobia, religious fanaticism, racism, mass hysteria. All found their ultimate expression in Auschwitz.”

Swallowing the bottle cap, Sarkos swerved toward Martin. “Don’t you see? It’s the only solution that can possibly work. No other theory comes close. Of course God has a dark side. Not just dark—evil. Radically, radically evil.”

Upon the Sovereign Sun (362)
Context: To explain, however, everything relating to the nature of this deity, is beyond the power of man, even though the god himself should grant him the ability to understand it: in a case where it seems, to me at least, impossible even mentally to conceive all its extent. And now that we have discussed so much, we must put as it were a seal upon this subject; and to stay a while and pass on to other points no less requiring examination. What then is this seal; and what comprises everything, as it were in a summary of the conception concerning the nature of the god? May He Himself inspire our understanding when we attempt briefly to explain the source out of which he proceeded; and what he is himself; and with what effects he fills the visible world. It must therefore be laid down that the sovereign Sun proceeded from the One God, — One out of the one Intelligible world; he is stationed in the middle of the Intelligible Powers, according to the strictest sense of "middle position;" bringing the last with the first into a union both harmonious and loving, and which fastens together the things that were divided: containing within himself the means of perfecting, of cementing together, of generative life, and of the uniform existence, and to the world of Sense, the author of all kinds of good; not merely adorning and cheering it with the radiance wherewith he himself illumines the same, but also by making subordinate to himself the existence of the Solar Angels; and containing within himself the unbegotten Cause of things begotten; and moreover, prior to this, the unfading, unchanging source of things eternal.
All, therefore, that was fitting to be said touching the nature of this deity (although very much has been passed over in silence) has now been stated at some length.

As quoted in Omnipotence and Other Theological Mistakes by Charles Hartshorne (1984)
Context: Appealing to his [Einstein's] way of expressing himself in theological terms, I said: If God had wanted to put everything into the universe from the beginning, He would have created a universe without change, without organisms and evolution, and without man and man's experience of change. But he seems to have thought that a live universe with events unexpected even by Himself would be more interesting than a dead one.

Gertrude (1910)
Context: If a man does not think too much, he rejoices at rising in the morning, and at eating and drinking. He finds satisfaction in them and does not want them to be otherwise. But if he ceases to take things for granted, he seeks eagerly and hopefully during the course of the day for moments of real life, the radiance of which makes him rejoice and obliterates the awareness of time and all thoughts on the meaning and purpose of everything. One can call these moments creative, because they seem to give a feeling of union with the creator, and while they last, one is sensible of everything being necessary, even what is seemingly fortuitous. It is what the mystics call union with God. Perhaps it is the excessive radiance of these moments that make everything else appear so dark. Perhaps it is the feeling of liberation, the enchanting lightness and the suspended bliss that make the rest of life seem so difficult, demanding and oppressive. I do not know. I have not travelled very far in thought and philosophy. However I do know that if there is a state of bliss and a paradise, it must be an uninterrupted sequence of such moments, and if this state of bliss can be attained through suffering and dwelling in pain, then no sorrow or pain can be so great that one should attempt to escape from it.
