In mathematics there's a type of book, bordering on the textbook but slightly different, that compiles examples to demonstrate the necessity of various conditions on theorems and the correct directions of implication. For example, to show that a connected space need not be path-connected one can construct the topologist's sine curve.
My question: are there any similar compilations in the philosophical literature? For instance, in epistemology the obvious set would be the Gettier cases (to show that JTB is an insufficient analysis), along with Armstrong's (?) barn facades and fake towns (to show that context seems to be important) and so on. In ethics we have Nozick's experience machine (the limits of hedonism).
Further, potentially-not-site-appropriate question: do people think such a compilation would be in any way valuble in philosophy?
Clarification: I used the term 'counterexamples' since that's the popular term in maths; I mean what I've hinted at in the examples above: a case which establishes a conditions or bounds for a theory.
