Virtù e vizi del concretismo

Concretism is the ontological thesis according to which possibilia (roughly: what renders true our statements about possibility) are concrete entities. The paper first outlines concretism, arguing that its sole founding thesis is that individuals across possible worlds are individuated by similitude. Among other things, this means that there is no need to postulate that there is no overlap among worlds. The main virtues and vices of concretism are then reviewed, and a novel vice is put forward: a failure in the reduction of modality due to the modal character of intrinsicness.
