**Shahid Rahman**, "Towards Dialogical Harmony", is presenting material related to his paper "Negation in the Logic of First Degree Entailment and Tonk. A Dialogical Study", comin out this year in G. Primiero et al.,

*(Anti)Realism. The Realism-Realism Debate in the Age of Alternative Logics*(Springer). I read this paper last fall and it was at times interesting and at times frustrating. His concept of "dialogical harmony" actually overlaps quite a bit with our investigations into different types of neutrality last fall. In particular, he accepts player independence. Now, the argument I gave back in August against player independence was:

First, structural rules which are wholly player neutral will result in the inconsistent logic: Proponent has a winning strategy for every atom p, so at least some asymmetry/nonneutrality in the rules is required.I am curious to see if he addresses this problem in the remainder of the talk; if he doesn't, I intend to ask him about it. Curiously, at least one version of particle rules for FDE-negation that he introduces is

*not*player neutral. --- I asked my question; I don't think I was able to express myself clearly, because his answer was "of course you have to have some asymmetry" in order to build a logic. So I'm not sure what his motivation for arguing for player neutrality is, nor how he gets the required asymmetry from his symmetric particle rules.
