Attempts to capture the distinction between categorical and dispositional states in terms of more primitive modal notions – subjunctive conditionals, causal roles, or combinatorial principles – are bound to fail. Such failure is ensured by a deep symmetry in the ways dispositional and categorical states alike carry modal import. But the categorical/dispositional distinction should not be abandoned; it underpins important metaphysical disputes. Rather, it should be taken as a primitive, after which the doomed attempts at reductive explanation can be transformed (...) into circular but interesting accounts. (shrink)

The world’s leading environmental advisory institutions look to ecological theory and research as an objective guide for policy and resource management decision-making. In addition to various theoretical merits of doing so, it is therefore crucially important to clear up confusions about ecology’s conceptual foundations and to make plain the basic workings of inferential methods used in the science. Through discussion of key moments in the genesis of the theoretical branch of ecology, this essay elucidates a general heuristic role of teleological (...) metaphor in ecological research and defuses certain enduring confusions and misguided criticisms of current work in ecology.

Recently, biologists and computer scientists who advocate the "strong thesis of artificial life" have argued that the distinction between life and nonlife is important and that certain computer software entities could be alive in the same sense as biological entities. These arguments have been challenged by Sober (1991). I address some of the questions about the rational reconstruction of biology that are suggested by these arguments: What is the relation between life and the "signs of life"? What work (if any) (...) might the concept of "life" (over and above the "signs of life") perform in biology? What turns on scientific disputes over the utility of this concept? To defend my answers to these questions, I compare "life" to certain other concepts used in science, and I examine historical episodes in which an entity's vitality was invoked to explain certain phenomena. I try to understand how these explanations could be illuminating even though they are not accompanied by any reductive definition of "life.". (shrink)

This paper illuminates primary epistemic functions of teleological characterizations in ecology through discussion of the historical and conceptual origins of the theoretical branch of ecology (§§1–2). I subsequently defuse enduring confusions about the use of teleological characterizations in ecology; with a focus on recent critical arguments by Sagoff in this journal (Sagoff, Synthese 193:3003–3024, 2016) and some other places (e.g., his Sagoff, Ethics, Policy, and Environment 16:239–257, 2013 and Sagoff, Studies in History and Philosophy of Science Part C, 2017) (§3). (...) The paper then culminates by collecting five generalizable novel insights attained through the forgoing discussion and outlining avenues for follow-up work that can build on the arguments laid out in this paper (§4).

Metaphysicians eager to engage with substantive, thoughtful, and provocative issues will be happy with John Heil’s From an Ontological Point of View. The book represents not only a sustained defence of a specific metaphysical theory, but also of a specific way of doing metaphysics. Put ontology first, Heil urges us, in order to remember that the original fascination of metaphysics wasn’t the question ‘what must the world be like in order to correspond neatly to our use of language?’, but rather (...) the altogether more fundamental ‘what must the world be like?’.

John Heil’s From an Ontological Point of View (Heil 2003) is a tremendous philosophical work. The neo-Lockean ontology the reader finds within its 267 pages is a sensible and refreshing alternative to the neo-Humean ontologies which presently occupy the vast majority of the metaphysical literature. What Heil offers is a much needed change in perspective. Nor are the strengths of the book limited to Heil’s willingness to approach central metaphysical problems in largely untried and unpopular way; the book is very (...) clear in its presentation, accessible to wide readership, and tightly argued throughout. Heil’s efforts in this book are to be applauded, and the result is one that warrants serious consideration by all those interested in serious metaphysics. But the interest should not end there: the lessons of Heil’s book are ones that almost all philosophers ought to take seriously. Despite the criticism that follows, my overall position should not be taken as anything short of a whole-hearted endorsement of Heil’s book. Nonetheless, when philosophy is one’s trade, there is always going to be something to disagree about, however much one is amenable to a view. (shrink)
