Storrs McCall presents an original philosophical theory of the nature of the universe based on a striking new model of its space-time structure. He shows that this theory can illuminate a wide variety of hitherto unresolved philosophical problems. These include: the direction and flow of time; the nature of scientific laws; the interpretation of quantum mechanics; the definition of probability; counterfactual semantics; and the notions of identity, essential
properties, deliberation, decision, and free will. A particular instance of the explanatory powers of the proposed space-time model is its account of quantum non-locality in the EPR and GHZ experiments.
Professor McCall argues that the fact that the model explains and throws light on such a broad range of problems constitutes strong evidence that the universe is as the model portrays it.
