The program that questions everything – except your intelligence – started off questioning the conventional wisdom that there would be no audience for a radio show about philosophy.  One hundred and ninety-nine programs later, Ken and John are hanging in there with large loyal audiences in the Bay Area and Oregon, outposts at over fifty stations across North America, and a huge internet following.  In their 200th program Ken and John compile a list of the Top 10 most pressing philosophical issues for the 21st century with help from you, their listeners, and three past guests: Jenann Ismael, Brian Leiter, and Martha Nussbaum.
