I don't know about the mediator, but I assume you know about this: en.wikipedia.org/wiki/Brams%E2%80%93Taylor_procedure

comment Has philosophy ever clarified mathematics?
To offer an interpretation: When a collection of related philosophical questions "stabilizes", it becomes a discipline. To then effectively philosophize about these questions one must internalize the methods of that discipline in order to sense philosophical nuance regarding these questions...but then you are doing research in the discipline, right? I'm not so sure this is the aim of philosophy, but if this is what you mean...that this "clustering" is a consequence of philosophy, then I agree.

comment Has philosophy ever clarified mathematics?
I should say that I agree with the irreducibility statement that "the philosophy of mathematics that elucidates mathematics is simply...mathematics".

comment Has philosophy ever clarified mathematics?
I am a bit wary, here. It seems like the OP is saying that the point of philosophy is to settle on "rigorous" method, which crystallizes into disciplines. I can't imagine a serious philosopher saying that philosophy is a movement toward method. I know one is not supposed to discuss things here, but I'd really love some clarification.

comment How does a mathematician choose on which problem to work?
@quid: What you write looks sound to me, and has the added benefit of helping me rationalize my having given an answer. Cheers!

comment How does a mathematician choose on which problem to work?
Although this question is broad, I think that JDH's point is a vital one. Anecdotes of how leading mathematicians choose their problems may serve to move mathematics forward by promoting productive attitudes that can be "mimicked" by a graduate student looking to find his own personal mathematical approach…something which requires a lot of "trying on".
