I thought I would try a picture for discussion:

The idea is that Wittgenstein's two philosophical stances polarised analytic philosophy from an early stage, that Carnap and Grice play the role of moderators gradually moving away from the two opposing extremes as they matured, and that the journey to "The City of Eternal Truth" is a continuation of these two processes which can be facilitated by dialogue between Carnap and Grice, through present philosophers whose sympathies lie with them (Jones and Speranza, and anyone else who wants to join in).
