The Seminars of Philosophy of Perception, Mind, and Language
The Seminars of Perception, Mind, and Language (former Seminars of Philosophy of Language and Mind) take place every year since 2001 at the Department of Philosophy of the University of Milan. The meetings aim at being an opportunity for people working in analytic philosophy to debate the latest directions of research.
The meetings are structured as a 45-50 minutes presentation, followed by an extensive discussion time. They are open to anyone interested in the topic, especially undergraduate and Ph.D. students. The language of the talks is either Italian or English.

Ontological Parsimony
Abstract: It is familiar that ontology matters to theory choice: more parsimonious theories should be preferred to less parsimonious ones. But as David Lewis pointed out, this Ockhamist principle can be understood in two ways, depending on whether parsimony is understood in quantitative or qualitative terms. The distinction between quantitative and qualitative parsimony is then used by Lewis to argue that his own theory of reality is in fact more parsimonious than one might suspect. Whether Lewis's argument is cogent remains a vexed question in the extant literature, and I shall argue that that once qualitative parsimony is properly understood, Lewis should concede that his defence fails and that his own theory is as qualitatively unparsimonious as any consistent theory could be.
