An actology--introduced by the first book in this series, Actology: Action, Change and Diversity in the Western Philosophical Tradition--understands reality as action in changing patterns. Actological Readings in Continental Philosophy reads a number of continental philosophers through this lens, and An Actology of the Given explores the concepts of the gift, givenness, and giving in the light of reality understood as action in changing patterns. Mark's Gospel: An Actological Reading is what it says it is. An Actological Metaphysic is a more systematic treatment of cosmology and of such concepts as truth, knowledge, causality, time, space, life, and society, to see what happens when they are understood actologically--that is, with reality understood as action in changing patterns. An Actological Theology similarly asks what Christian theology might look like if God, the universe, ourselves, and everything else is understood as action in changing patterns.
