Impossibilia

Abstract

http://dx.doi.org/10.5007/1808-1711.2016v20n1p81The paper defends the so-called extended modal realism, a theory according to which there are concrete impossible worlds. Firstly, modal realism is presented. Next, the way of how its ontology enriched by impossible worlds should look like in order to save its main theoretical virtues is pursued. Finally, I argue for a claim that metaphysical impossibility equals to dissimilarity between worlds instantiating distinct metaphysical structures.
