Universalist and nihilist answers to philosophical questions may be extreme, but they are clear enough. Aliquidist answers, by contrast, are typically caught between the Scylla of vagueness and indeterminacy and the Charybdis of ungroundedness and arbitrariness, and steering a proper middle course—saying exactly where in the middle one is going to settle—demands exceptional navigating powers. I myself tend to favor extreme answers precisely for this reason. Here, however, I consider one sense in which Something may claim superiority over its polar (...) competitors, Everything and Nothing, when it comes to answerting the ontological question, “What is there?”.

This paper addresses the most fundamental question in metaphysics, Why is there something rather than nothing? The question is framed as a question about concrete entities, Why does a possible world containing concrete entities obtain rather than one containing no concrete entities? Traditional answers are in terms of there necessarily being some concrete entities, and include the possibility of a necessary being. But such answers are threatened by metaphysical nihilism, the thesis that there being nothing concrete is possible, and the (...) subtraction argument for this thesis, an argument that is the subject of considerable recent debate. I summarize and extend the debate about the argument, and answer the threat it poses, turning the tables on it to show how the subtraction argument supports a cosmological argument for a necessary being.

La critique du nihilisme par Lowe est soumise à une évaluation. Le nihilisme semble impliquer un engagement à l'existence d'entités abstraites et Lowe utilise le principe de dépendance (PD) — les abstraits dépendent des concrets — pour bloquer la référence à des entités abstraites : les nombres sont dits dépendre de concrets. On défendra l'idée que cette forme de fictionnalisme n'est pas innocente et que nous devons sérieusement envisager l'alternative que constitue le platonisme. On défendra une forme de platonisme, le (...) platonisme particularisé. En conclusion on proposera de renoncer au PD. (shrink)

Metaphysical nihilism is the thesis that there could have been no concrete objects. Thomas Baldwin (1996) offers an argument for metaphysical nihilism. The premisses of the argument purport to provide a procedure of subtraction that can be iterated until we reach a world where no concrete objects exist. Gonzalo Rodriguez-Pereyra (1997) finds fault with Baldwin’s argument, modifies it, and claims to have proved metaphysical nihilism. My primary aim is to show that Rodriguez-Pereyra’s alleged proof rests on a false assumption. The (...) assumption is that, necessarily, if there are no concrete* objects (in the sense Rodriguez-Pereyra defines), then there are no concrete objects. My secondary aim, with which I begin, is to formulate and then strengthen a succinct version of the subtraction argument. (shrink)

In this dissertation I suggest an answer to the famous question ‘why is there something rather than nothing?’ I argue that there is something because there could not have been nothing. The focus of my discussion is the empty possible world of metaphysical nihilism, and the first chapter is a rejection of the only prominent argument for that position; the subtraction argument. In the second part of my discussion I construct a positive argument against metaphysical nihilism, I assume, as is (...) common in the literature, that inconceivability provides evidence of impossibility. I establish the inconceivability of nothingness taking propositional imagining to be the core of conceivability, claiming that we have no experience of nothingness in the relevant sense and are unable to imagine it. Finally, I suggest that a distinction should be made between everyday use of the term ‘nothing’, and the sense under discussion here. The inconceivability of nothingness applies only in the latter case. Given that nothingness is inconceivable, we have prima facie reason to suppose that the empty world is impossible. I conclude that given the failure of the subtraction argument and in light of my argument against metaphysical nihilism, that position should be rejected. (shrink)
