Outline of Final Research Achievements

The outcome of my research is threefold: (I) I have developed an conceptual spaces account of how vagueness and gradability in concepts may emerge. This approach turned out to be very fruitful and has led to a number of papers (published in Synthese, Journal of Philosophical Logic, LNAI). (II) I write a long and thorough critique of the received idea that vagueness is a universally pervasive phenomenon; this idea has led to various logical paradoxes which effectively challenge the very idea that our conception of vague is coherent. The outcome of this is a very long paper, which is under review with the international journal of MIND. (III) I organised a large-scale international conference on vagueness and probability (in 2013) at the University of Tokyo. I am guest-ediitor of a special issue with SYNTHESE, in which more than ten papers that emerged from this conference are going to be published.
