The structure of the second, Or so-Called modal version of anselm's ontological argument is discussed in relation to various systems of alethic modal logic. It is argued that there are three current problems standing in the way of acceptance of the argument, Each related to its modal structure, And each an analogue of a traditional objection to anselm's original argument. Two of these problems can probably be solved, But the third remains recalcitrant.

It is argued that a little-Discussed notion of prima facie good (and a related notion of a "basic value experience") can throw light on some of the most vexing problems of value theory, About the meaning of 'good', The naturalistic fallacy, The objectivity of value, The fact-Value distinction and intrinsic value. The notion of prima facie good is formally analogous to w d ross's notion of prima facie duty, But is more general (applying to value generally) and (it is argued) (...) is more useful and less problematic. Views of spinoza, Ross, Moore, Perry and recent value theorists are discussed. (shrink)

The early chapters of this book deal with what the author calls the "dilemma of obligability.". The apparent dilemma is that obligability is not compatible with either determinism or indeterminism. The author believes the dilemma can be avoided by denying the principle that "'ought' implies 'can'," or the principle that obligability entails substitutability. This is because, as the dilemma is presented in the book, it is generated by the assumption that obligability entails substitutability together with arguments to the effect that (...) substitutability is not compatible with either determinism or indeterminism. In support of this latter claim, arguments are marshalled in Chapters 4 and 5 against hypothetical analyses of "could have done otherwise" favored by compatibilists, on the one hand, and against incompatibilist analyses, on the other. Both are found wanting. The author argues that the only way out of the dilemma is to deny that obligability entails substitutability. In Chapter 6, he gives further reasons, involving concrete examples, for denying the "'ought' implies 'can'" principle. Chapters 7 and 8 shift gears somewhat in order to defend a modified ethical intuitionism; and then Chapter 9 returns to the obligability issue, arguing that the ultimate justification for holding persons obligable is that it helps bring about "patterns of behavior deemed socially desirable". The final chapter is a critique of divine command theories of obligability. (shrink)
