I'm a phil grad too, and agree. Too many inaccessible dry canonical texts. And no mention of Quine! I'd pick texts that animate the subject; with motivation the classics become more accessible. So for PhilSci I'd have Feyerabend's Farewell to Reason, for PhilMathLogic, Hofstadter's Godel, Escher, Bach. Quine's Essays covers logic, metaphysics, logic and language. And to keep things up to date I'd put Bostrom's Simulation argument.
