In 2002, I worked up some cartoons for a philosophy textbook that two of my professors at UTM were preparing (Philosophical Questions, Fieser & Lillegard, Oxford UP, 2004). Most of them appear below. You can find the textbook here.
Many of these cartoons are available as designs on mugs, T-shirts, and other products at GadflyCreations.com.
