Some philosophers hold that objective consequentialism is false because it is incompatible with the principle that “ought” implies “can”. Roughly speaking, objective consequentialism is the doctrine that you always ought to do what will in fact have the best consequences. According to the principle that “ought” implies “can”, you have a moral obligation to do something only if you can do that thing. Frances Howard-Snyder has used an innovative thought experiment to argue that sometimes you cannot do what will in (...) fact have the best consequences because you do not know what will in fact have the best consequences. Erik Carlson has raised two objections against Howard-Snyder’s argument. This paper examines Howard-Snyder’s argument as well as Carlson’s objections, arguing that Carlson’s objections do not go through but Howard-Snyder’s argument fails nonetheless. Moreover, this paper attempts to show that objective consequentialism and other objectivist moral theories are compatible with the principle that “ought” implies “can”. Finally, this paper analyses a special kind of inability: ignorance-induced inability. (shrink)

I argue that free will and determinism are compatible, even when we take free will to require the ability to do otherwise and even when we interpret that ability modally, as the possibility of doing otherwise, and not just conditionally or dispositionally. My argument draws on a distinction between physical and agential possibility. Although in a deterministic world only one future sequence of events is physically possible for each state of the world, the more coarsely defined state of an agent (...) and his or her environment can be consistent with more than one such sequence, and thus different actions can be “agentially possible”. The agential perspective is supported by our best theories of human behaviour, and so we should take it at face value when we refer to what an agent can and cannot do. On the picture I defend, free will is not a physical phenomenon, but a higher-level one on a par with other higher-level phenomena such as agency and intentionality. (shrink)

Decision-making typically requires judgments about causal relations: we need to know the causal effects of our actions and the causal relevance of various environmental factors. We investigate how several individuals' causal judgments can be aggregated into collective causal judgments. First, we consider the aggregation of causal judgments via the aggregation of probabilistic judgments, and identify the limitations of this approach. We then explore the possibility of aggregating causal judgments independently of probabilistic ones. Formally, we introduce the problem of causal-network aggregation. (...) Finally, we revisit the aggregation of probabilistic judgments when this is constrained by prior aggregation of qualitative causal judgments. (shrink)

In rejecting the Principle of AlternatePossibilities (PAP), Harry Frankfurt makes useof a special sort of counterfactual of thefollowing form: ``he wouldn''t have doneotherwise even if he could have''''. Recently,other philosophers (e.g., Susan Hurley (1999,2003) and Michael Zimmerman (2002)) haveappealed to a special class of counterfactualsof this same general form in defending thecompatibility of determinism andresponsibility. In particular, they claim thatit can be true of agents that even if they aredetermined, and so cannot do otherwise, theywouldn''t have done otherwise even if (...) they couldhave. Using as a central case an argument ofSusan Hurley''s, I point out that thecounterfactuals in question are both``interlegal'''' and ``indeterministic'''', and I raisedoubts about whether this special class ofcounterfactuals have clear truth conditions. Finally I suggest that acknowledging thesepoints leads to an appreciation of the realstrength of Frankfurt-style examples. (shrink)

In a recent paper, Christian List has argued for the compatibilism of free will and determinism. Drawing on a distinction between physical possibility and agential possibility, List constructs a formal two-level model in which the two concepts are consistent. This paper's first contribution is to show that though List's model is formally consistent, philosophically it falls short of establishing a satisfactory compatibilist position. Ensuingly, an analysis of the shortcomings of the model leads to the identification of a controversial epistemological assumption (...) implicit in the statements of both compatibilist and incompatibilist positions. Arguing that this assumption is not currently satisfied, the paper's second contribution is to show that neither the compatibilist nor the incompatibilist position is presently well-founded.

The Blockage Argument is designed to improve upon Harry Frankfurt’s famous argument against the Principle of Alternative Possibilities by removing the counterfactual intervener altogether. If the argument worked, then it would prove in a way that Frankfurt’s argument does not that moral responsibility does not require any alternative possibilities whatsoever, not even the weakest “flicker of freedom”. -/- Some philosophers have rejected the Blockage Argument solely on the basis of their intuition that the inability to do otherwise is incompatible with (...) moral responsibility. I will argue, however, that it is not merely the inability to do otherwise by itself but rather the inability to do otherwise in combination with the absence of a counterfactual intervener that is incompatible with moral responsibility. If I cannot do otherwise and it is not because of a counterfactual intervener, then it must be the case that I am being forced to choose and therefore act as I do, in which case I cannot be morally responsible for this action. -/- Because the Blockage Argument fails, and because it was really the only way to establish that moral responsibility does not require any alternative possibilities whatsoever, it follows that moral responsibility does indeed require at least one alternative possibility in any given situation. But it turns out that this conclusion does not tip the balance in favor of incompatibilism over compatibilism. It would have if blockage and determinism were equivalent. But they are not. Unlike blockage, determinism is compatible with certain counterfactuals that compatibilists traditionally believed the ability to do otherwise reduces to. So even though moral responsibility is incompatible with blockage, it does not necessarily follow that moral responsibility is incompatible with determinism. (shrink)

Any satisfactory account of freedom must capture, or at least permit, the mysteriousness of freedom—a “sweet” mystery involving a certain kind of ignorance rather than a “sour” mystery of unintelligibility, incoherence, or unjustifiedness. I argue that compatibilism can capture the sweet mystery of freedom. I argue first that an action is free if and only if a certain “rationality constraint” is satisfied, and that nothing in standard libertarian accounts of freedom entails its satisfaction. Satisfaction of this constraint is consistent with (...) the universal causal predetermination of action (UCP). If UCP is true and the rationality constraint satisfied, there’s a sense in which our actions are explanatorily (though not necessarily causally) overdetermined. While it seems plausible (given UCP) that our actions are so overdetermined, it seems utterly mysterious why they should be so overdetermined. Compatibilism’s capacity to accommodate this mystery is a mark in its favor. (shrink)

Physical determinism is a metaphysical thesis about the natural world whose consequences for freedom and moral responsibility have been widely discussed. In this paper, I articulate a different form of determinism, motivational determinism, which claims that all intentional action is causally determined by the prior motivational state of the agent. Motivational determinism was defended in a simple form by Hume, but has been neglected in recent philosophical literature. I show that there are important reasons that support the plausibility of MD. (...) I then compare MD with libertarian and physical deterministic theories of agency and note that MD has various attractive features. I show that MD is much more threatening to moral responsibility than physical determinism. I conclude that MD is an interesting theory of human agency that deserves wide attention. (shrink)
