The ancient doctrine that ‘no one crosses the same river twice’ is extended. No thinker thinks twice; and, to put the matter more generally, no subject experiences twice. This is what Locke ought to have meant by his doctrine of time as a ‘perpetual perishing.’ ... In the philosophy of organism it is not ‘substance’ which is permanent, but ‘form.’ Forms suffer changing relations; actual entities ‘perpetually perish’ subjectively, but are immortal objectively. Actuality in perishing acquires objectivity, while it loses subjective immediacy. (Alfred North Whitehead, Process and Reality)
What is done in the world is transformed into a reality in heaven, and the reality in heaven passes back into the world. By reason of this reciprocal relation, the love in the world passes into the love in heaven and floods back again into the world. In this sense, God is the great companion—the fellow-sufferer who understands.' (Alfred North Whitehead, Process and Reality)
