The free will problem is an old one. Like anything old, it has changed over time. This book has three aims, therefore: to introduce the free will problem as it exists now; to explain how the problem has come to take its present form; and to suggest how the problem in its present form might be solved.
This book is meant to provide not merely an introduction, but also an original contribution to its subject. The views presented here are developed at greater length in other books and articles that I am in the course of publishing. The relevant references are to be found at the end in the section of Further Reading.
My thanks to Tim Crane, Peter Goldie, Jennifer Hornsby, Tim Norman, and Martin Stone, to an OUP reader, and to my wife Judy. Each has read the text of this book in its entirety, and made many very helpful suggestions.
