Philosophers have long noticed the similarity of identity over time and identity across worlds. Despite this similarity, analogous views on these matters are not always taken equally seriously. Four-dimensionalism is one of the most well-known accounts of identity over time. There is a clear modal analogue of four-dimensionalism, on which objects are modally extended and their trans-world identity is a matter of having distinct modal parts located in different possible worlds. Yet this view, which we might call ‘five-dimensionalism,’ is rarely (...) discussed or defended, in comparison to its temporal counterpart. I argue that five-dimensionalism is at least as plausible as four-dimensionalism and deserves serious consideration as an account of trans-world identity. The strategy is to show that arguments typically used in defence of four-dimensionalism can be adapted to defend five-dimensionalism as well. A powerful consideration in favour of four-dimensionalism is the fact that it provides an elegant and unified solution to a variety of puzzles concerning material coincidence. I show that such puzzles come in equally troubling modal varieties and that five-dimensionalism provides an equally unified and elegant solution to them. (shrink)

J’argumente que les Quiniens qui sont sceptiques par rapport à la distinction analytique/synthétique devraient aussi être sceptiques quant à la distinction entre conflits verbaux et factuels. Je développe une objection à la distinction entre conflits verbaux et factuels, dérivée des objections à la distinction analytique/synthétique. J’explique ensuite de quoi se compose le scepticisme qui en résulte. En définitive, ces sceptiques devraient reconnaître la différence entre conflits verbaux et factuels, mais pensent que certaines tâches philosophiques ne peuvent être performées.

First published in 1975, this is a book of general intellectual interest about the role of the university in contemporary society and that of university teachers in relation to their subjects, their students, and their wider political commitments. Alan Montefiore offers preliminary analyses of the family of concepts most often invoked in discussions of these problems, taking the central dispute to be between those who hold a 'liberal' view of the university and those who regard this notion as illusory, dishonest (...) or undesirable. Six academics, representing, discuss issues of substantive conflict in light of Montefiore's initial distinctions. The volume is of particular interest to students of political and social philosophy, and political and educational theory. It is also intended for a wider readership among those who care about the political status of the universities and recognize the importance and difficulty of the problems involved in this. (shrink)

In this paper, I argue that various disputes in ontology have important ramifications and so are worth taking seriously. I employ a criterion according to which whether a dispute matters depends on how integrated it is with the rest of our theoretical projects. Disputes that arise from previous tensions in our theorizing and have additional implications for other issues matter, while insular disputes do not. I apply this criterion in arguing that certain ontological disputes matter; specifically, the disputes over concrete (...) possible worlds and coincident material objects. Finally, I consider how one could show that some ontological disputes do not matter, using a Platonism/nominalism dispute as an example. (shrink)
