Horgan (1993) proposed that "superdupervenience" - supervenience preserving physicalistic acceptability - is a matter of robust explanation. I argued against him (1999) that (as nearly all physicalist and emergentist accounts reflect) superdupervenience is a matter of Condition on Causal Powers (CCP): every causal power bestowed by the supervenient property is identical with a causal power bestowed by its base property. Here I show that CCP is, as it stands, unsatisfactory,for on the usual understandings of causal power bestowal, it is trivially (...) satisfied or falsified. I offer a revision of CCP which incorporates the evident fact that causal powers are grounded in fundamental forces. (shrink)

Hare has written a clear, brief, and readable introduction to ethics which looks at all the fundamental problems of the subject.

John F. Post argues that physicalistic materialism is compatible with a number of views often deemed incompatible with it, such as the objectivity of values, the irreducibility of subjective experience, the power of the metaphor, the normativity of meaning, and even theism.

In a series of papers written over the last two decades, Terence Horgan has articulated a radical position on truth and metaphysics that he calls contextual semantics. According to Horgan, we can abandon referentialism – or the idea that truth is always and everywhere understood in terms of the referential relations between words and world – while still sensibly believing in a mind-independent world. The centerpiece of contextual semantics is that it allows for some flexibility about truth: statements of different (...) sorts can be true in different ways depending on the degree to which they correspond to the world. In this paper, I explore the consequences of this position.While I believe that contextual semantics has significant advantages, there is a deep tension between Horgan'stolerance of more than one kind of truth and his belief in one type of reality – a tension that threatens to undermine the entire position.

Jonathan Lowe argues that metaphysics should be restored to a central position in philosophy, as the most fundamental form of rational inquiry, whose findings underpin those of all other disciplines. He portrays metaphysics as charting the possibilities of existence, by idetifying the categories of being and the relations of ontological dependency between entities of different categories. He proceeds to set out a unified and original metaphysical system: he defends a substance ontology, according to which the existence of the world s (...) one world in time depends upon the existence of persisting things which retain their identity over time and through processes of qualitative change. And he contends that even necessary beings, such as the abstract objects of mathematics, depend ultimately for their existence upon there being a concrete world of enduring substances. Within his system of metaphysics Lowe seeks to answer many of the deepest and most challenging questions in philosophy. (shrink)

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

In this wide-ranging study, Levine explores both sides of the mind-body dilemma, presenting the first book-length treatment of his highly influential ideas on the How does one explain the physical nature of an experience? This puzzle, the "explanatory gap" between mind and body, is the focus of this work by an influential scholar in the field.

Ontological Naturalism holds that our fundamental ontology contains only those generally natural objects, properties, and relations required by our best scientific theory. Logical principles are thought of as being normative of correct inference and as involving necessary truths and relations. Necessary relations are stronger than the relations described by science; norms are traditionally thought to be separate from the descriptive project of science. Yet, ontological theories, including ontological naturalism, employ logic freely without offering an account of logical normativity and necessity. (...) It appears that logical properties and relations are prima facie non-natural. If so, then ontological naturalism paradoxically presupposes the presence of non-natural properties and relations as a part of the ultimate fundamental ontology. I explore this tension between logic and ontology as a means to clarifying the standards of acceptability for ontological theories generally and as a means to clarifying the character of logical discourse. I conclude that all proposed ontological theories must provide a substantive account of logic which respects its intrinsic modal and normative character as a minimal test of meta-ontological acceptability.
