Taking collective agency for serious.

The talk will explore a framework in which agents can have two very basic propositional attitudes: asserting and denying. Different sets of postulates characterizing the reasonable behavior of the classic-like agents involved with be seen to give rise to different logics, with either deterministic or nondeterministic broadly truth-functional characterizations. This illustrates an approach that generalizes and overcomes some difficulties confronted by both bivalent semantics and society semantics. In particular, I will show how societies can be built that fully take into account the reasoning of their constituent agents on what concerns the satisfaction of complex sentences beyond a reduced list of `initial formulas'. The role and effects of considering different disciplines for information collecting and processing will be emphasized.
