Abstract

This chapter introduces some concepts that help exploring the ontological import of universal logic. It studies the notions of an antilogic and counterlogic associated with each logic and shows some of their properties. It presents the notion of galaxy, as the class of possible worlds compatible with a given logic. We explore some consequences of these developments.
