One function of philosophy is to help us see obvious truths more clearly and deeply. Another function is to challenge ideas that appear obvious but that may be fundamentally mistaken. Process philosophy is an efort to think clearly and deeply about the obvious truth that our world and our lives are dynamic, interrelated processes and to challenge the apparently obvious, but fundamentally mistaken, idea that the world (including ourselves) is made of things that exist inde- pendently of such relationships and that seem to endure unchanged through all the processes of change.
