Philosophy of Time Travel (PHIL10125) Course Guide 2020/21 Course Organiser: Dr. Alasdair Richmond, [email protected] Dugald Stewart Building, room 6.11, 0131 650 3656 I hope to be offering office hours as well but they will obviously be contingent on how the re-opening of University proceeds in the wake of Covid-19. So look out for further announcements but chats via (e.g.) Skye or Teams will be possible regardless. Course Secretary: Ms. Ann Marie Cowe, [email protected] Undergraduate Teaching Office, Dugald Stewart Building, room G.06, 0131 650 3961 Department of Philosophy School of Philosophy, Psychology and Language Sciences University of Edinburgh Course Aims and Objectives This course will offer detailed seminars on key philosophical issues in the philosophy of time travel, largely with an analytical slant. Students should end this course conversant with a range of significant metaphysical (and other) issues surrounding time travel. No detailed logical, scientific or metaphysical expertise will be assumed, and the course is intended to be accessible to students with a wide range of philosophical interests and aptitudes. Intended Learning Outcomes To develop further the philosophical skills, and to extend and deepen the philosophical knowledge, acquired in previous philosophy courses. Transferable skills that students will acquire or hone in taking this course should include the following: written skills (through summative essays) oral communication skills (through lecturer-led and/or student-led seminar discussions) presentation skills (through giving and criticising student presentations) analytical skills (through exploring a carefully-chosen series of philosophical texts) ability to recognise and critically assess an argument. Lecture Times and Locations Second semester Day/ Time: Again, this is all rather contingent on how re-opening proceeds. However please note that: I) all lecture content is already available in pre-recorded form on the LEARN page for this course, and ii) we have resources to allow this course to proceed fully online if required. I hope to have (at the very least) small group face-to-face meetings but rest assured, the course can carry on as planned even if direct meetings prove impracticable. (I have delivered entire courses electronically before, I stress.) Lecture Content and Readings Asterisked items below are available from JSTOR. All other journal items should be available via the electronic journals access facilitated by the Library / MyEd. Any problems, do please let me know. Main texts: *** Please note: electronic alternatives to print resources can always be provided if (e.g.) the Main Library proves difficult of access. There is no irreplaceable reading that is only available in print. As always, please ask if I can help at all. *** This is a research-led course, driven by my ongoing monograph and spin-off articles on sundry aspects of time travel. Just recently (2018 and 2020 respectively), the Oxford University Press have published Ryan Wasserman’s Paradoxes of Time Travel and Nikk Effingham’s Time Travel: Probability and Impossibility, the first full-length books on the philosophy of time travel. Both books can be recommended in their entirety and should be available (again in their entirety) electronically via the Main Library. (My review of Wasserman appeared in Analysis in 2018. By the time the course is actually delivered, my review of Effingham should also be available, again from Analysis.) This next is still probably the best available introduction to space and time in general: Barry Dainton, Time and Space, Chesham, Acumen, 2001, second edition Durham Acumen 2010, multiple copies should be available in the Library Hub Reserve (at shelf-mark BD632 Dai). I spent academic years 2008-2009 and 2016-17 on research-leave, working on a raft of time-travel related articles plus a book. On request, I am happy to circulate draft papers and other works-in-progress of my own. (Just please don’t post my draft stuff anywhere – I’ll just end up looking silly / even sillier. Quite where my book is after Wasserman and Effingham is another story …) Please note that the following lists of readings are prioritised, with the most important / useful readings at the top. So the recommended way to tackle the suggested readings is to start at the top of each list and work downwards. If you read only one thing for each seminar, read the top one.
