The Nature of God explores a perennial problem in the philosophy of religion.

This book, one of the first full-length studies of the modalities to emerge from the debate to which Saul Kripke, David Lewis, Ruth Marcus, and others are contributing, is an exploration and defense of the notion of modality de re, the idea that objects have both essential and accidental properties. Plantinga develops his argument by means of the notion of possible worlds and ranges over such key problems as the nature of essence, transworld identity, negative existential propositions, and the existence (...) of unactual objects in other possible worlds. He also applies his logical theories to the elucidation of two problems in the philosophy of religion: the problem of evil and the ontological argument. (shrink)

In an impressive series of books and articles, Alvin Plantinga has developed challenging new versions of two much discussed pieces of philosophical theology: the free will defense and the ontological argument.' His treatment of both subjects has provoked a tremendous amount of critical comment. What has not been generally noticed', however, is that when taken together, Plantinga's views on these two subjects lead to a very serious problem in philosophical theology. The premises of his version of the ontological argument, when (...) combined with the presuppositions of the free will defense, appear to entail that God is not free to choose between good and evil and thus is not "good" in the distinctively moral sense of this word. In the present paper, I shall explain how this problem arises, and explore two different ways of trying to deal with it. (shrink)

It is argued that a theorist like Leibniz who believes that a consequentially omnibenevolent God created the actual world must presuppose that there is a best possible world. If so, then if God did create this world, there is no best, and He has as essential properties each of His perfections, God's omnibenevolence must be understood in terms of some alternative concept of omnibenevolence. Such an alternative is offered, one consistent with there being no best world, and one that does (...) not presuppose the truth of the consequentialist moral principle that one ought to do the best one can.

Several years ago I came across a marvelous little paper in which Hector-Neri Castaneda shows that standard versions of act utilitarian l ism are formally incoherent. I was intrigued by his argument. It had long seemed to me that I had a firm grasp on act utilitarianism. Indeed, it had often seemed to me that it was the clearest and most attractive of normative theories. Yet here was a simple and relatively uncontrover sial argument that showed, with only some trivial (...) assumptions, that the doctrine is virtually unintelligible. The gist of Castaneda's argument is this: suppose we understand act utilitarianism to be the view that an act is obligatory if and only if its utility exceeds that of each alternative. Suppose it is obligatory for a certain person to perform an act with two parts - we can call it 'A & B'. Then, obviously enough, it is also obligatory for this person to perform the parts, A and B. If act utilitarianism were true, we appar ently could infer that the utility of A & B is higher than that of A, and higher than that of B (because A & B is obligatory, and the other acts are alternatives to A & B).

_The Divine Attributes_is an engaging analysis of the God of Judaism, Christianity, and Islam from the perspective of rational theology.

This book addresses a dilemma concerning freedom and moral obligation. If determinism is true, then no one has control over one's actions. If indeterminism is true, then no one has control over their actions. But it is morally obligatory, right or wrong for one to perform some action only if one has control over it. Hence, no one ever performs an action that is morally obligatory, right or wrong. The author defends the view that this dilemma can be evaded but (...) not in a way traditional compatibilists about freedom and moral responsibility will find congenial. For moral obligation is indeed incompatible with determinism but not with indeterminism. He concludes with an argument to the effect that, if determinism is true and no action is morally obligatory, right or wrong, then our world would be considerably morally impoverished as several sorts of moral appraisal would be unjustified.

_The Divine Attributes_is an engaging analysis of the God of Judaism, Christianity, and Islam from the perspective of rational theology.

The principal aim of this book is to develop and defend an analysis of the concept of moral obligation. The analysis is neutral regarding competing substantive theories of obligation, whether consequentialist or deontological in character. What it seeks to do is generate solutions to a range of philosophical problems concerning obligation and its application. Amongst these problems are deontic paradoxes, the supersession of obligation, conditional obligation, prima facie obligation, actualism and possibilism, dilemmas, supererogation, and cooperation. By virtue of its normative (...) neutrality, the analysis provides a theoretical framework within which competing theories of obligation can be developed and assessed. This study is a major contribution to metaethics that will be of particular interest to all philosophers concerned with normative ethical theory. (shrink)
