(I've still got some blank days at the end of the semester for contemporary analytic philosophy, so if anyone has any suggestions for essential essays (20–30 pages) suitable for juniors and seniors, I'd love to hear them.)
Anything more determinate you’re looking for? Do you just want papers that are good essays, in our view, or do you want papers that are representative of analytic philosophy?
If the latter, Frege’s “On Sense and Reference” (perhaps also “Function and Concept” and “Concept and Object”), Russell’s “On Denoting,” Quine’s “Two Dogmas,” and selections from Wittgenstein’s Philosophical Investigations are all classics which are difficult but accessible to undergraduates. I think they’re intensely interesting, but they may find some of them rather dry. If they are not so thick-skinned, the Investigations stand on their own.
I think Anscombe’s “Modern Moral Philosophy” is a great paper and is accessible, albeit difficult.
