1920s, Process and Reality: An Essay in Cosmology (1929)
Context: In all philosophic theory there is an ultimate which is actual in virtue of its accidents. It is only then capable of characterization through its accidental embodiments, and apart from these accidents is devoid of actuality. In the philosophy of organism this ultimate is termed creativity; and God] is its primordial, non-temporal accident. In [[monistic philosophies, Spinoza's or absolute idealism, this ultimate is God, who is also equivalently termed The Absolute. In such monistic schemes, the ultimate is illegitimately allowed a final, eminent reality, beyond that ascribed to any of its accidents. In this general position the philosophy of organism seems to approximate more to some strains of Indian, or Chinese, thought, than to western Asiatic, or European, thought. One side makes process ultimate; the other side makes fact ultimate.

"Looking Back on the Spanish War" (1943)
Context: I have little direct evidence about the atrocities in the Spanish civil war. I know that some were committed by the Republicans, and far more (they are still continuing) by the Fascists. But what impressed me then, and has impressed me ever since, is that atrocities are believed in or disbelieved in solely on grounds of political predilection. Everyone believes in the atrocities of the enemy and disbelieves in those of his own side, without ever bothering to examine the evidence.
