Writers such as Stalnaker and Dummett have argued that specific features of subjunctive conditional statements undermine the principle of bivalence. This, paper is concerned with rebutting such claims. 1. It is shown how subjective conditionals pose a prima facie threat to bivalence, and how this threat can be dissolved by a distinction between the results of negating a subjective conditional and of negating its consequent. To make this distinction is to side with Lewis against Stalnaker in a dispute about possible (...) worlds semantics for such conditionals, and reasons are given for doing so. 2. These arguments are extended to answer Dummett''s claim that behaviourist and phenomenalist analyses in terms of subjunctive conditions violate bivalence. This answer is shown to be compatible with the principle that hypothetical statements are true only in virtue of categorical facts. (shrink)

Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds and his theory of laws of nature.

Realism concerning a given subject-matter is characterised as a semantic doctrine with metaphysical consequences, namely as the adoption, for the relevant class of statements, of a truth-conditional theory of meaning resting upon the classical two-valued semantics. it is argued that any departure from classical semantics may, though will not necessarily, be seen as in conflict with some variety of realism. a sharp distinction is drawn between the rejection of realism and the acceptance of a reductionist thesis; though intimately related, neither (...) entails the other. realism is to be classified as "naive", "semi-naive" or "sophisticated": the first of these involves an all but unintelligible epistemological component.

The rapidly increasing numbers of elderly people in our society have raised some important moral questions: How should we distribute social resources among different age groups? What does justice require from both the young and the old? In this book, Norman Daniels offers the first systematic philosophical discussion of these urgent questions, advocating what he calls a "lifespan" approach to the problem: Since, as they age, people pass through a variety of institutions, the challenge of caring for the elderly becomes (...) the prudent allocation of public resources among the various stages of people's lives. Using this philosophical approach, Daniels addresses specific public policy issues such as the allocation of medical funds, the adequacy of long-term care, current Medicare cost-containment measures, and the equitable distribution of income support over the lifespan and between generations.
