ARGUMENTS FROM NOTHING: GOD AND QUANTUM COSMOLOGY

This essay explores a simple argument for a Ground of Being, objections to it, and limitations on it. It is nonsensical to refer to Nothing in the sense of utter absence, hence nothing can be claimed to come from Nothing. If, as it seems, the universe, or any physical ensemble containing it, is past‐finite, it must be caused by an uncaused Ground. Speculative many‐worlds, pocket universes and multiverses do not affect this argument, but the quantum cosmologies of Alex Vilenkin, and J. B. Hartle and Stephen Hawking, which claim that the universe came from literally nothing, would. I argue that their novel project cannot work for reasons both physical (their “nothing” is actually a vacuum state governed by eternal physical laws) and methodological (physical theory cannot explain the emergence of the physical per se). Thus my argument stands. However, as David Hume showed, a posteriori arguments like mine infer a creation, and Creator, of a certain character, namely, a stochastic concept of creation and a panentheistic, partly physical Creator lacking omniscience and omnipotence. Rather than undermining the cosmological argument, as Hume intended, these limitations liberate the concept of the Ground from unnecessary problems, as Hartshorne suggested.     

CONCEIVABILITY AND MODAL KNOWLEDGE

Abstract: This article is a discussion of Hume's maxim Nothing we imagine is absolutely impossible. First I explain this maxim and distinguish it from the principle Whatever cannot be imagined (conceived), is impossible. Next I argue that Thomas Reid's criticism of the maxim fails and that the arguments by Tamar Szábo Gendler and John Hawthorne for the claim that “it is uncontroversial that there are cases where we are misled” by the maxim are unconvincing. Finally I state the limited but real value of the maxim: it does help us, in certain cases, reliably to make up our minds. Along the way I show that Reid, his criticism of the maxim notwithstanding, actually employs it, and I furthermore argue that the principle What is inconceivable, is impossible is spurious.

INFINITE REGRESS ARGUMENTS

Abstract

Gerald Cohen's critique of John Rawls's theory of justice is that it is concerned only with the justice of social institutions, and must thus arbitrarily draw a line between those inequalities excluded and those allowed by the basic structure. Cohen claims that a proper concern with the interests of the least advantaged would rule out ‘incentives’ for ‘talented’ individuals. I argue that Rawls's assumption that the subject of justice is the basic structure of society does not arbitrarily restrict the concerns of political justice, as Cohen claims. Further, I argue that it does not allow ‘deep’ inequalities within a just basic structure. When properly understood, Rawls's theory of justice is strongly egalitarian, taken as a theory of fairness in the way the burdens and benefits of social cooperation are distributed, even if it is not as egalitarian as Cohen wishes.     

THE STRUCTURE OF SCEPTICAL ARGUMENTS

It is nowadays taken for granted that the core radical sceptical arguments all pivot upon the principle that the epistemic operator in question is 'closed' under known entailments. Accordingly, the standard anti-sceptical project now involves either denying closure or retaining closure by amending how one understands other elements of the sceptical argument. However, there are epistemic principles available to the sceptic which are logically weaker than closure but achieve the same result. Accordingly the contemporary debate fails to engage with the sceptical problem in its strongest form.     

MATHEMATICAL EXPLANATION AND INDISPENSABILITY ARGUMENTS

We defend Joseph Melia's thesis that the role of mathematics in scientific theory is to 'index' quantities, and that even if mathematics is indispensable to scientific explanations of concrete phenomena, it does not explain any of those phenomena. This thesis is defended against objections by Mark Colyvan and Alan Baker.
