Philosophy of space and time Source for time travel issues: The Metaphysics of Star Trek Time travel stories share one basic assumption Both the future and the past are, in some sense, “there” to be traveled to Called the “block universe” view Time is pretty much like space Why think that? Why think that anything “exists” other than the present? Time travel interpretations Star Trek : timelines rewritten based on past events Back to the Future (?): alternative timelines Branching, many possible only one actual Changes in past put you on another branch All branches are “out there” in some sense Parallel universes Timelines are completely independent of one another Unlike the right-branching, alternative timelines Hence, not truly time travel But if the two universes evolved similarly, it might look like time travel E.g., a world that never evolved past the age of dinosaurs And if there are infinitely many parallel universes Some of them look like ours In fact, in an infinite multiverse, an infinite number of parallel universes look a lot like our own

“All You Zombies” So it turns out that Jane has himself as both father and mother (He’s also the recruiter it turns out) Trace the steps: how did it happen? Issue 1, Time travel problem: How did the temporal loop get started? I.e., how was Jane born the first time? If she had other parents, what happened to them? Did they leave her at an orphanage? Even so, when she was first raped/seduced in the park, that couldn’t have been her as a man Hence she couldn’t have given birth to herself ANS: timeline rewritten a la Star Trek. Does that help? Issue 2, Is Jane-the-mother really the same person as Jane-the-daughter ANS 1: Probably not: genetic differences Which traits are passed on is a matter of probability Unlikely that the daughter carried precisely the same genome as the mother or father Plus the problem of random mutations ANS 2: If that people souls (or minds), Jane-the-mother and Jane-the-daughter cannot have the same soul If not, then they cannot be the same identical person Caveat: How does one get a soul? 1. Pre-existence and reincarnation 2. Creationism 3. Traducianism 4. Emergence Possible Sources: Encyclopedia of philosophy; Howard A. Slaatte, Contemporary philosophies of religion; Louis P. Pojman Philosophy of religion : an anthology; Robert Adams , The virtue of faith and other essays in philosophical theology Possible test questions: 1. Are Jane the mother and Jane the daughter identically the same person? Why or why not? 2. Give two ways in which a new soul is created 3. Is Jane her own grandparents? Why or why not?
