# Real Time II **Opening (not a real abstract):** Real Time II is about the most intriguing and basic question in metaphysics: what is time? Does it really flow or does it just seem to? How do past, present and future differ? Why can we only act and have experiences in the present? Why can we not see the future, or affect the past—or can we: is time travel possible? How does time differ from space? What gives it its direction? All these questions are answered in this book, which is a complete reworking of D.H. Mellor’s influential ‘new tenseless theory of time’, developed in his Real Time (1981). While defending and developing the themes of that book in the light of later work in metaphysics, semantics and cosmology, Mellor gives new accounts of what statements about the past, present and future mean and what makes them true, of the nature of change and causation, and of what distinguishes time from space, gives **Authors:** [[Mellor]]
