In this book, we will look at some of the central issues in the philosophy of computer science. The book is not designed to answer all (or even any) of the philosophical questions that can be raised about the nature of computers and computer science. Rather, it is designed to “bring you up to speed” on a conversation about these issues— to give you some of the background knowledge about them—so that you can read the literature for yourself and perhaps become part of the conversation by contributing your own views.
