Process Metaphysics: An Introduction to Process Philosophy Book

This book takes a wide view of process metaphysics and does not clearly base itself on any particular historical author (like Bergson or Whitehead). The first chapter gives a brief historical overview after which the basics are given, then the book examines the different topics where process metaphysics has been applied in chapters on particulars, universals, philosophy of nature, persons, logic and epistemology, science, theology, and philosophy.
Process metaphysics in general, and in this book too, often defines itself in opposition to its greatest competitor: substance metaphysics. It sees the world in processes, which are intrinsically temporal, stretching from past to future, whereas 'thing'-like substances only exist in time, the concept requiring in addition processual thought to allow for change (Aristotle needs two books so to speak, the Categories and the Metaphysics, to explain the world). I like to think of it in terms of physics: a process has a velocity as it were, there is a rate of change associated with it, a derivative in mathematics. It does not fall prey to Zeno's paradoxes, which substance metaphysics would have a great deal of trouble explaining if relying on substance only.
Furthermore, process has no clear borders and is interconnected, relational. My body is a temporarily stable confluence of processes that uphold a relational structure between its parts and is not clearly distinguished from the surrounding environmental processes. Atoms go in and out in an orderly fashion while the total arrangement of atoms is maintained. Where environment ends and body begins is not at all clear at the micro-level. Clearly, this way of looking at the world is more aligned with scientific insights (and also inspired by them), notably the theory of evolution and physics at the smallest scales, where even particles lose their substantiality.
And while substance has been prominent in the past and is so at present in the (in my opinion) largely sterile metaphysics departments, process-thought has gained popularity among the physical sciences and the philosophy of physics, which is (again, in my opinion) the only place where any real understanding in these matters will ever come from.
