When I was a grad student at MIT, Richard Cartwright used to assign us philosophical problem sets. Here is one that I am giving my grad students tomorrow.
In ‘The man drinking the martini is tall’, what object is the definite description about according to… Frege, Russell post-1905, Kripke, Strawson, and Donnellan?
[Hint: The question has a false presupposition in several of these cases. To answer it, point out where those lie.]
