Objective consequentialism is often criticized because it is impossible to know which of our actions will have the best consequences. Why exactly does this undermine objective consequentialism? I offer a new link between the claim that our knowledge of the future is limited and the rejection of objective consequentialism: that ‘ought’ implies ‘can’ and we cannot produce the best consequences available to us. I support this apparently paradoxical contention by way of an analogy. I cannot beat Karpov at chess in (...) spite of the fact that I can make each of many series of moves, at least one of which would beat him. I then respond to a series of objections. In the process I develop an account of the ‘can’ of ability. I conclude with some remarks about the bearing this attack has on subjective consequentialism. (shrink)

I argue for a version of "ought" implies "can". In particular, I argue that it is necessarily true that if an agent, S, ultima facie ought to do A at T', then there is a time T* such that S can at T* do A at T'. In support of this principle, I have argued that without it, we cannot explain how it is that, in cases where agents cannot do the best thing, they often ought to do some alternative (...) action - such as get help or do the promised action later; nor can we explain the phenomenon of necessary enablers or the phenomenon of more stringent prima facie obligations overriding less stringent ones in cases where the agent cannot fulfill both.

The fact that our asking God to do something can make a difference to what he does underwrites the point of petitionary prayer. Here, however, a puzzle arises: Either doing what we ask is the best God can do or it is not. If it is, then our asking won’t make any difference to whether he does it. If it is not, then our asking won’t make any difference to whether he does it. So, our asking won’t make any difference (...) to whether God does it. Our asking is therefore pointless. In this paper, we try to solve this puzzle without denying either that God must do the best he can or that petitioning God can make a difference to what he does. (shrink)

Imagine that there exists a good, essentially omniscient and omnipotent being named Jove, and that there exists nothing else. No possible being is more powerful or knowledgable. Out of his goodness, Jove decides to create. Since he is all-powerful, there is nothing but the bounds of possibility to prevent him from getting what he wants. Unfortunately, as he holds before his mind the host of worlds, Jove sees that for each there is a better one. Although he can create any (...) of them, he can't create the best of them because there is no best. Faced with this predicament, Jove first sorts the worlds according to certain criteria. For example, he puts on his left worlds in which some inhabitants live lives that aren't worth living and on his right worlds in which every inhabitant's life is worth living; he puts on his left worlds in which some horrors fail to serve an outweighing good and on his right worlds in which no horror fails to serve an outweighing good. (We encourage the reader to use her own criteria.) Then he orders the right hand worlds according to their goodness and assigns to each a positive natural number, the worst of the lot receiving '1', the second worst '2', and so on. Next, he creates a very intricate device that, at the push of a button, will randomly select a number and produce the corresponding world. Jove pushes the button; the device hums and whirs and, finally, its digital display reads '777': world no. 777 comes into being. (shrink)

We argue that Michael Peterson's and William Hasker's attempts to show that God and gratuitous evil are compatible constitute miserable failures. We then sketch Peter van Inwagen's attempt to do the same and conclude that, to date, no one has shown his attempt a failure.

In “Divine Freedom,” I argue that morally significant incompatibilist freedom is a great good. So God possesses morally incompatibilist freedom. So, God can do wrong or at least can do worse than the best action He can do. So, God is not essentially morally perfect. After careful consideration of numerous objections, I conclude that this argument is undefeated.

Agnes's brakes fail. Should she continue straight into the busy intersection or should she swerve into the field? Add to the story, what Agnes does not and cannot know, that continuing into the intersection will cause no harm, whereas swerving into the apparently empty field will cause a death. I evaluate arguments for the claim that she should enter the intersection, i.e. for objectivism about right and wrong; and arguments for the claim that she should swerve, i.e. for subjectivism about (...) right and wrong, and conclude that subjectivism is more plausible. I also consider the view that ‘ought’ and ‘wrong’ are systematically ambiguous, that she subjectively ought to swerve and that she objectively ought to enter the intersection. I argue that most versions of this suggestion are unworkable, and that even the best version is less plausible than pure subjectivism. (shrink)

This paper discusses the Principle of Normative Invariance: ‘An action’s moral status does not depend on whether or not it is performed.’ I show the importance of this principle for arguments regarding actualism and other variations on the person-affecting restriction, discuss and rebut arguments in favor of the principle, and then discuss five counterexamples to it. I conclude that the principle as it stands is false; and that if it is modified to avoid the counterexamples, it is gutted of any (...) interest or power. (shrink)

Satisficing and maximizing versions of consequentialism have both assumed that rightness is an alI-or-nothing property. We argue thal this is inimical to the spirit of consequentialism, and that, from the point of view of the consequentialist, actions should be evaluated purely in terms that admit of degree. We first consider the suggestion that rightness and wrongness are a matter of degree. If so, this raises the question of whether the claim that something is wrong says any more than that it (...) is bad. We consider the possibility that a consequenlialist should simply equate wrongness with badness. We reject this on the grounds that there is not a satsifactory way for a consequentialist to account for the badness of actions, as opposed to states of affairs. We explore two concepts of wrongness: to do something wrong is to be blameworthy; and the fact that something is wrong creates a reason not to do it. We argue that the first of these is not available to the consequentialist because of her views on blame, and that the second is just as much a feature of badness as of wrongness. We conclude that the consequentialist can make no sense of the concept of wrongness. (shrink)

This is a reply to William Rowe, "The Problem of No Best World," Faith and Philosophy (1994).

Many Christian theodicists believe that God's creating us with the capacity to love Him and each other justifies, in large part, God's permitting evil. For example, after reminding us that, according to Christian doctrine, the supreme good for human beings is to enter into a reciprocal love relationship with God, Vincent Brummer recently wrote: In creating human persons in order to love them, God necessarily assumes vulnerability in relation to them. In fact, in this relation, he becomes even more vulnerable (...) than we do, since he cannot count on the steadfastness of our love the way we can count on his steadfastness.... If God did not grant us the ability to sin and cause affliction to him and to one another, we would not have the kind of free and autonomous existence necessary to enter into a relation of love with God and with one another.... Far from contradicting the value which the free will defence places upon the freedom and responsibility of human persons, the idea of a loving God necessarily entails it. In this way we can see that the free will defence is based on the love of God rather than on the supposed intrinsic value of human freedom and responsibility.1 And Peter van Inwagen recently put the same point this way.

“The Pearl of Great Price” is a short story that explores the ways faith can go wrong. The central character, Janet, a single mom in a dead end job, is drawn into a multi-level marketing scheme, Benevite, by an unscrupulous salesman. She is encouraged to believe in herself and her dream and to give everything she has to it. She is fed the standard clichés to the effect that you can achieve whatever you want if you try hard enough. In (...) the end her faith in her dream leads to the loss of her relationship with her child and other losses. Her pursuit exhibits many of the standard features of faith, belief, desire, resilience, tenacity, passion, and yet she does not save herself. The story is not meant as an indictment of faith in general, but as an acknowledgement of the fact that faith can be a vice and an exploration of when this might be so. (shrink)

Martin Peterson argues for two interesting and appealing claims: multi-dimensionalism and degrees of rightness. Multi-dimensionalism is the view that more than one factor determines whether an act is right. According to Peterson’s multi-dimensionalism, these factors are not simply ways of achieving some greater aggregate good. Degrees of rightness is the view that some actions are more wrong or less right than others without being entirely wrong. It is of course, compatible with this, that some actions are right or wrong to (...) a maximal degree, or entirely right or wrong. Multi-dimensionalism and degrees are taken to be intertwined. On Peterson’s view, if there were only one dimension, we wouldn’t need degrees; where only one dimension applies, an act is entirely right or entirely wrong. Peterson claims that degrees of rightness or wrongness arise only because there are multi-dimensions, and that an act cannot be entirely right if it is wrong on some dimension. I shall argue against both of these claims. (shrink)

This is a review of Peter van Inwagen's collection of essays. It corrects a typesetter’s deletion of 75% of the review originally published in _Faith and Philosophy_15, 1998: 397-399.

This is a basic logic text for first-time logic students. Custom-made texts from the chapters is an option as well. And there is a website to go with text too.

This volume collects nine essays published by Peter van Inwagen between 1977 and 1995. Part I features, among other things, modal skepticism with respect to ontological arguments and arguments from evil. Part II addresses certain tensions Christians may feel between modern biology, critical studies of the New Testament, and the comparative study of religions, on the one hand, and Christian orthodoxy, on the other. Part III deploys a formal logic of relative identity to model the internal consistency of the orthodox (...) doctrines of the Trinity and the Incarnation. In what follows, we summarize and reflect on five essays. (shrink)
