The title reflects my conviction that, viewed semantically, modal logic is fundamentally dialogical; this conviction is based on the key role played by the notion of bisimulation in modal model theory. But this dialogical conception of modal logic does not seem to apply to modal proof theory, which is notoriously messy. Nonetheless, by making use of ideas which trace back to Arthur Prior (notab...

The governance of open multi-agent systems is particular important since those systems are composed by heterogeneous, autonomous and independently designed agents. Such governance is usually provided by the establishment of norms that regulate the actions of agents. Although there are several approaches that formally describe norms, there are still few of them that propose their implementation....

Yuval-Davis discusses three interconnected questions relating to identity. She first examines whether and in what ways the notion of identity should be theorized, on the one hand, and empirically researched, on the other, focusing on the opposing views of Stuart Hall and Robin Williams. She then examines the contested question of what is identity, positioning it in relation to notions of belong...

Although time is recognized as an important factor relating dialogical selves, space is the primary metaphor used when discussing alternative I-positions in dialogical relations (e.g. Hermans 2001, 2002; Hermans and Kempen 1993; Raggatt 2000). However, more recently, there has been a growing theoretical interest in the temporal dimension of dialogicality (e.g. Bertau and Gonçalves 2007; Bhatia ...

A dialogical version of (modal) epistemic logic is outlined, with an intuitionistic variant. Another version of dialogical epistemic logic is then provided by means of the S4 mapping of intuitionistic logic. Both systems cast new light on the relationship between intuitionism, modal logic and dialogical games.
