I took a course a few years ago in university entitled Philosophy of Language. We spent much time analyzing sentences like "Peter believes that London is pretty." I know it was a Russell essay, but which one? Also in discussion was the sentence "Aristotle taught Alexander the Great". (If Aristotle wasn't the teacher, the name escapes me, but I'm sure someone knows what I'm getting at.)
Sorry for the late reply: ''Pierre believes London is pretty'' is from Saul Kripke's famous paper 'A Puzzle About Belief', published in 1979. Aristotle WAS in fact Alexander's teacher, and if memory serves Russell mentions that in 'On Denoting' from 1905. It's a very famous essay, it's likely you looked at it in your PoL course :)
Kripke also mentions Aristotle as the teacher of Alexander several times (partly in reference to Russell) in his 1980 book 'Naming and Necessity'.
