Experience and the Arrow

The debate over the temporal arrow is a debate over what fundamental ontology is needed for the temporal asymmetry of the universe, which determines the fact that time seems to be oriented or directed from earlier to later. This temporal asymmetry underlies (or, as some might argue, is the same as) the asymmetrical fact that the past is fixed while the future is open, as well as the global asymmetries of counterfactual, causal and agential direction. I explore the metaphysics of the temporal direction within the context of empirical work in psychology and cognitive science. I argue that, in our debate over the metaphysics of the temporal arrow, we need to explore some of the deep connections between our cognitive response to the world and our metaphysical theory of the temporal direction.
