—Alfred North Whitehead, (1861-1947) English mathematician and philosopher
Alfred North Whitehead was first a mathematician and logician who co-authored with Bertrand Russell Principia Mathematica, a colossally ambitious attempt to derive all mathematics from a small set of axioms using logic, which later was shown to be untenable by Kurt Gödel. However, Whitehead's philosophy and religious writings hearken more toward Eastern thought with the idea of dynamic reality, called Process Philosophy, rather than a static, object centered one.
Driven first by science (as seen with Dewey), the twentieth century saw tremendous and diverse changes in thinking about God and religion, and the idea which gained the widest traction, despite formidable historical hurdles, was that God is not impassive nor immutable. Especially after WWI, the God of St. Anselm and the theological notion of impassibility, were widely rejected by theologians and the laity alike. After the war an immovable mover made little sense; after democracy, a supreme being, likewise. And no one more ingeniously or reasonably initiated these changes in the west than Alfred North Whitehead.
For Whitehead, God does not stand impassively outside the system and remain independent of it—a last resort deus ex machina to hold it all together. Rather, God is an integral element in the whole and participates actively in its struggles and concerns.
Whitehead proposed a metaphysics which many theologians adopted. God and existence itself, are described as processes, activity. We find this echoed by many of today's physicists and cosmologists who prefer events to particles. Dividing the world into substances and qualities (particles and properties) is the commonsense way to cope with everyday life and individual scientific problems, but when looking at the ultimate nature of reality, Whitehead insisted "We must start with the event as the ultimate unity of natural occurrence."—particles are but instantaneous manifestations of the process.
So, what is meaningful is not attributes, but how God acts or relates to the rest of reality. Actualities (including ourselves) arrive from interaction with God in a primordial sense which is "the unlimited conceptual realization . . . of potentiality." But we (via each actual occasion) also relate in a consequent sense which is how God relates to physical reality. God prehends all actual occasions of the physical world as they emerge. Each occasion or event impacts God through this prehension (i.e. the non-sensory sympathetic perception of antecedent experiences). God is not impassive but actively changes. In this way God is not a concept apart from our temporal reality—the nature of God requires there be realities other than God. While God's existence is neither uncertain nor dependent on the actions of others, Whitehead poetically says, “It is as true to say that God creates the World, as that the World creates God.” God is essentially in a give-and-take relationship with the world.
God affects us; and we, God—through God's understanding (prehension). As Whitehead imaginatively says, God is "the poet of the world." God suffers as we suffer. The description calls to mind J. D. Salinger's (son of) God as Seymour's "Fat Lady".
Obviously, the metaphysics is difficult to quickly summarize and I've omitted major portions, but it is built, not from a need for God, but from a rational view of reality. I think you can see that Whitehead's metaphysics leaves no room for the supernatural. Indeed, God is defined by what experientially is. Per Whitehead, apart from experiences "there is nothing, nothing, nothing, bare nothingness." I started thinking that Whitehead was the first quantum philosopher, and then recently discovered there are a number of books and lectures on quantum mechanics and Whitehead philosophy. The crazy thing about his work is that it appeals to hardcore scientists as well as Christian theologians who use it in an attempt to rescue Christianity from the blows received during the twentieth century.
Here are a few other prescient quotes by Whitehead on religion:
"Religion will not regain its old power until it can face change in the same spirit as does science."
"Idolatry is the necessary product of static dogmas"
And a favorite, remember this is a mathematician:
"The worship of God is not a rule of safety — it is an adventure of the spirit, a flight after the unattainable. The death of religion comes with the repression of the high hope of adventure."
