The Value of Objections


It is the fashion of the present time to disparage negative logic — that which points out weaknesses in theory or errors in practice without establishing positive truths.

Personal Identity


Listen to philosopher Christopher Shields (University of Oxford) on Philosophy Bites talking about personal identity — what makes an individual the same person despite change over time.

This became a topic of particular interest to me when I was doing research for a paper that I presented in July 2007, “Labyrinths of the Self: Different Characters, Identical Bodies in Battlestar Galactica”. I used John Locke’s ideas then and, because I am turning this short conference paper into an essay for publication, I later came across Derek Parfit’s work. Shields discuses Locke, but it is refreshing that he also considers examples from classical philosophy. The philosopher argues for a definition of personal identity as involving the “individual life directionality” of a subject.
