A modest proposal concerning laws, counterfactuals, and explanations - - Why be Humean? -- Suggestions from physics for deep metaphysics -- On the passing of time -- Causation, counterfactuals, and the third factor -- The whole ball of wax -- Epilogue : a remark on the method of metaphysics.

The basic idea of Maudlin's superb book is methodological: ‘metaphysics, insofar as it is concerned with the natural world, can do no better than to reflect on physics. Physical theories provide us with the best handle we have on what there is, and the philosopher's proper task is the interpretation and elucidation of those theories. In particular, when choosing the fundamental posits of one's ontology, one must look to scientific practice rather than to philosophical prejudice’ .The apparently diverse (...) topics covered by the book's six chapters are united in bearing out this basic idea. They do so with considerable care and sophistication. The chapters also champion a campaign against David Lewis's thesis of Humean Supervenience. Lewis's thesis says that everything actual supervenes on the distribution of intrinsic qualities across points in space-time.Chapter 1 claims that laws of …. (shrink)

Is time-travel possible? Like most intriguing problems that lie within the shared locus of physics, metaphysics and logic, this question admits of many interpretations, each of which engenders a different line of research. At its most anemic, the issue can be just: Is it possible to tell a story about travel into the past that contains no explicit contradictions? Under the stimulation of physical concerns it may develop into a more challenging problem: Do the laws of (...) class='Hi'>physics, as best we understand them, admit of solutions that contain closed time-like curves? And next: Would it be physically possible for a massive object to travel along one of those curves into its own local past? Then: Are the known facts about our universe consistent with it being such a world? And finally: Is time-travel in our universe technologically possible? When prodded in this direction our original question arrives at last on the drawing boards of the engineers, having passed successively through the precincts of the theoretical physicists, the mathematicians, and the astronomers.
