Along the way, I decided to make a mind map covering each of the major thinkers that have influenced western philosophy. This is my version of a "cheat sheet of philosophy", and I decided that it might be worth sharing with others. It is by no means complete or comprehensive. It probably does infringe on the copyright of Teach 21 and the lecturers whose notes I cribbed from liberally. I can only hope that they don't send me a DMCA Take Down Request. So until then, here it is.
It goes in approximately chronological order, starting with the Greeks and working clockwise around to the modern thinkers. I try to give a summary of what I found useful or important about each thinker, and probably have overlooked, oversimplified and overstated quite a few things.
If I've made any egregious errors, please leave a comment and I'll fix what I can:
