Why does anything happen? What is the best account of natural necessity? In this book, William A. Bauer presents and defends a comprehensive account of the internal structure of causal powers that incorporates physical intentionality and information. Bauer explores new lines of thought concerning the theory of pure powers (powerful properties devoid of any qualitative nature), the place of mind in the physical world, and the role of information in explaining fundamental processes. He raises probing questions about physical modality and fundamental properties, and explores the possibility that physical reality and the mind are unified through intentionality. His book will be valuable for researchers and students working in metaphysics, philosophy of science, and philosophy of mind.
