Critical thinking: Primary concepts/ a brief textbook by James DiGiovanna, CUNY John Jay College

“Abstract

I’ve been teaching critical thinking for many years, and I’ve developed a short, free, Creative Commons-licensed text that’s useful for a brief (maybe 3 week?) critical thinking section in any intro philosophy or composition course (or really, just about any course; it’s been used at my college by professors from a number of departments.)”
