Thursday classes

For Introduction to Philosophy the quiz question today was tell me what your favorite song is (send me a link if you have one). My favorite song is this one as sung by Francois Hardy.

The list of philosophers for term papers includes all of these: Living Philosophers Charles Murray Thomas Metzinger http://en.wikipedia.org/wiki/Thomas_Metzinger Owen Flanagan http://en.wikipedia.org/wiki/Owen_Flanagan Joseph Margolis http://www.cla.temple.edu/philosophy/faculty/joseph-margolis/ Peter Sloterdijk http://www.newrepublic.com/article/113387/peter-sloterdijks-philosophy-gives-reasons-living Jurgen Habermas http://www.egs.edu/library/juergen-habermas/biography/ Sam Harris http://www.samharris.org/ Charles Taylor http://www.thenation.com/article/162667/sentimentality-or-honesty-charles-taylor# Alister McGrath http://users.ox.ac.uk/~mcgrath/ Daniel Dennett http://ase.tufts.edu/cogstud/dennett/index.html Martha Nussbaum http://www.law.uchicago.edu/faculty/nussbaum/ Hilary Putnam http://www.fas.harvard.edu/~phildept/putnam.html Slavoj Zizek http://www.egs.edu/faculty/slavoj-zizek/biography/ Alain Badiou http://www.egs.edu/faculty/alain-badiou/biography/ Peter Singer https://www.princeton.edu/~psinger/ David Chalmers http://consc.net/chalmers/ Judith Butler http://www.egs.edu/faculty/judith-butler/biography/ Fredric Jameson http://literature.duke.edu/people?Gurl=&Uil=812&subpage=profile A.C.
