Stubborn Questions & Elusive Answers (Kenwood)

If I tell someone I'm lying, am I telling the truth?  If I could travel back in time, could I prevent my own birth?  If I take an object apart and then reconstruct it, do I have the same object?  If these or similar questions entice you, please join the discussion in Stubborn Questions and Elusive Answers..  We will begin with an overview of logic (what is and isn't good argumentation) and then dive into problems presented by some of the many things we take for granted, such as time, motion, and identity, to consider not all is what it may seem.
