The best possible option of impossible worlds: Hybrid Modal Realism

Résumé

In this paper I reconstruct the merits and drawbacks of the concretist and abstractionist theories of possible worlds and face them with the challenge of impossible worlds. I show how these two types of theories deal with the problem of impossibilities, and argue that the best option is two advance the so-called hybrid modal realism, namely concret possible worlds and abstract impossible worlds. Finally, as a conclusion, I highlight some of the disadvantages of this view as well and note the possibility of a Carnap-like solution.
