The key-terms "language", "knowledge" and "metaphysics" arguably shapemost of the recent researches in analytic philosophy. This volume aim toaddress some of the currently debated issues revolving around thesethree fundamental areas and, in particular: can the notion of"descriptive name" be extended to names of natural kinds? What does itmean for a belief to be justified? Is there a principled way to draw thedistinction between causal and non causal relations? Do futurecontingent claims require us to employ a notion of relative truth? Inwhat sense analytic sentences could be taken to be known a posteriori?The twelve papers collected in this volume arise from a selection ofthose presented during the First Graduate Conference of the ItalianSociety for Analytic Philosophy (SIFA) held at the University of Paduain September 2007. The authors are all young and brilliant scholarscoming from some of the most prestigious universities in the world:University College (London), Nottingham, Princeton, Kentucky, Stanford,Eastern Piedmont, St. Andrews, Hebrew University of Jerusalem, Duhram,Catholic University of Leuven, London School of Economics.
