This book is an exploration of what it takes for an event to count as an
action. I first became interested in this topic nearly a decade ago
while working on a different topic. I kept coming across philosophers
making claims about the nature of action that seemed false or at least
dubious to me. As a consequence I turned to the philosophy of action
directly, to get to the heart of the matter. I have wrestled with this
territory ever since. I hope that, with this book, I have finally earned
the intuitions that put me at odds with the philosophers I was
originally reading. This book develops ideas in Part Two of my doctoral
dissertation, which I wrote at Queen's University in Kingston, Ontario,
Canada. I loved being at Queen's, for both professional and personal
reasons. My thanks go to the Social Sciences and Humanities Research
Council of Canada for financial support as a doctoral candidate. Steve
Leighton and Ronald de Sousa were readers for my dissertation. They
provided some early and invaluable challenges to the ideas developed
here. My deepest debt of gratitude is owed to David Bakhurst, my
supervisor. I learned a lot from David; this book would not be the same
without his help.
