While there is considerable disagreement on the precise nature of material objecthood, it is standardly assumed that material objects must be spatial. In this paper, I provide two arguments against this assumption. The first argument is made from largely a priori considerations about modal plenitude. The possibility of non-spatial material objects follows from commitment to certain plausible principles governing material objecthood and plausible principles regarding modal plenitude. The second argument draws from current philosophical discussions regarding theories of quantum gravity and (...) the emergence of spacetime. When it is appreciated what possible worlds these current theories commit us to, the possibility of non-spatial material objects will follow. Thus, either route will lead us to the possibility of non-spatial material objects. The significance of this result is that we need to revise our accounts of material objecthood to both accommodate these possibilities and the theories that lead to them. (shrink)

This paper examines two objections to the infinitist theory of epistemic justification, namely “the finite mind objection” and “the distinction objection.” It criticizes Peter Klein’s response to the distinction objection and offers a more plausible response. It is then argued that this response is incompatible with Klein’s response to the finite mind objection. Infinitists, it would seem, cannot handle both objections when taken together.

In this article, I offer a critical evaluation of non-reductive physicalism as articulated and defended by Nancey Murphy. I argue that the examples given by Murphy do not illustrate robust emergence and the philosophical idea of downward causation. The thesis of multiple realizability is ontologically neutral, and so cannot support the idea of the causal efficacy of higher-level properties. Supervenience is incompatible with strong emergence. I also argue for the fruitful relationship between emergence theory and panpsychism pertaining to the metaphysical (...) issue of the origin and nature of mind. (shrink)

In this paper a class of languages which are formal enough for mathematical reasoning is introduced. Its languages are called mathematically agreeable. Languages containing a given MA language L, and being sublanguages of L augmented by a monadic predicate, are constructed. A mathematical theory of truth (shortly MTT) is formulated for some of those languages. MTT makes them fully interpreted MA languages which posses their own truth predicates. MTT is shown to conform well with the eight norms formulated for theories (...) of truth in the paper 'What Theories of Truth Should be Like (but Cannot be)', by Hannes Leitgeb. MTT is also free from infinite regress, providing a proper framework to study the regress problem. Main tools used in proofs are Zermelo-Fraenkel (ZF) set theory and classical logic. (shrink)

I argue that the best interpretation of the general theory of relativity has need of a causal entity, and causal structure that is not reducible to light cone structure. I suggest that this causal interpretation of GTR helps defeat a key premise in one of the most popular arguments for causal reductionism, viz., the argument from physics.

A systematic theory of naturalism, bridging metaphysics and the science of complexity and emergence.

Paul Churchland argues that the continuity of human intellectual development provides evidence against folk psychology and traditional epistemology, since these latter find purchase only at the later stages of intellectual development. He supports this contention with an analogy from the history of thermodynamics. Careful attention to the thermodynamics analogy shows that the argument from continuity does not provide independent support for eliminative materialism. The argument also rests upon claims about continuity which do not support the claim that the continuity of (...) intellectual development is evidence for the elimination of folk psychology. Traditional epistemology and folk psychology should not yet be abandoned. (shrink)

This paper starts from the familiar premise that psychological anti-individualism is incompatible with materialism. It attempts to state more clearly what this incompatibility consists in, and — rather than arguing in detail for any particular resolution — to inquire whether this incompatibility admits any resolution. However, the paper does offer a conditional argument concerning the possibility that the incompatibility is genuine and cannot be resolved. Provided that anti-individualism and materialism cannot be squared, and anti-individualism is correct, it follows that materialism (...) has to be abandoned. If so, the situation is not as disastrous as it might at first seem. We need not, in consequence of our inability to construe a coherent metaphysics of mind, give up on intentional vocabulary any more than we must stop, in consequence of our inability to make sense of induction, anticipating the future.

The best extant statement of the epistemic regress problem makes assumptions that are too strong. An improved version assumes only that that reasons require support, that no proposition is supported only by endless regresses of reasons, and that some proposition is supported. These assumptions are individually plausible but jointly inconsistent. Attempts to explain support by means of unconceptualized sensations, contextually immunized propositions, endless regresses, and holistic coherence all require either additional reasons or an external condition on support that is arbitrary (...) from the believer's own point of view.

Moral intuitionism, once an apparently moribund metaethical position, has seen a resurgence of interest of late. Robert Audi, a leading moral intuitionist, has argued that in order for a moral belief to qualify as intuitional, it must fulfill four criteria: it must be non-inferential, firmly held, comprehended, and pre-theoretical. This paper centers on the fourth and seemingly most problematic criterion: pre-theoreticality. The paper begins by stipulating the defensibility of the moral cognitivism upon which moral intuitionism turns. Next, the paper develops (...) the distinction between semantic and epistemic pre-theoreticality, and goes on to explore and reject the putative ubiquity of the theoreticality of first-order moral discourse: it argues that on a defensible understanding of theoryhood, both semantic and epistemic pre-theoretical moral belief is not only possible, but in fact frequently realized. The paper then briefly explores and rebuts objections to (epistemic) pre-theoreticality issuing from (i) the “Cornell Realists” and (ii) considerations of the epistemic relevance of the epistemic/valuational background of moral belief. The paper concludes that, so far as the pre-theoreticality criterion is concerned, moral intuitionism remains in the running as a viable thesis regarding foundationally justified first-order moral belief and knowledge.

This essay is an appreciative engagement with Karl Peters's Dancing with the Sacred (2002). Peters achieves a naturalistic theology of great power. Two themes are covered here. The first is how Peters gives ontological footing for a naturalistic conception of God conceived as the process of creativity in nature. Peters achieves this by conceiving creativity in terms of Darwinian random variation and natural selection combined with the notion of nonequilibrium thermodynamics. He gives ontological reference for a conception of God similar (...) to Henry Nelson Wieman's idea of creative transformation. The second theme is how Peters succeeds in translating this nonpersonal conception of God into a powerful view of naturalistic religion that can shape a religious form of life. The key is that Peters's God can be understood as present in experience. Peters provides naturalistic interpretations of grace and the cruciform structure of creativity; the latter addresses the problem of evil in a nuanced fashion. I conclude with three critical comments about Peters's environmental ethics, his use of the notion of mystery, and his failure to have a robust conception of human fault or sin. (shrink)

. Nonreductive physicalism, as opposed to reductionism, enjoys wide popularity by virtue of being regarded as comporting with the traditional image of human beings as free and ontologically unique without the difficulties of mind-body dualism. A consideration of reasons, both good and bad, for which reductionism is rejected suggests instead that the move to nonreductive physicalism does nothing to mitigate the implications of a physicalist account of human nature.
