Actions are usually grouped into one of several moral categories. Familiar ones include the morally required, the morally permitted, and the morally prohibited. These categories have been expanded and/or refined to include the supererogatory and the “suberogatory”. Some eschew deontic categories such as the above, but nevertheless allow the existence of two comparative moral categories, i.e., the morally better or morally worse. At the risk of adding to the clutter, I want to explore the possibility of yet a further category, (...) viz., amoral action, or actions that, strictly speaking, lack any moral status whatsoever. I think admitting the existence of amoral actions is not only plausible in its own right, but has consequences for our understanding the nature of moral obligation. (shrink)

I argue that when determining whether an agent ought to perform an act, we should not hold fixed the fact that she’s going to form certain attitudes (and, here, I’m concerned with only reasons-responsive attitudes such as beliefs, desires, and intentions). For, as I argue, agents have, in the relevant sense, just as much control over which attitudes they form as which acts they perform. This is important because what effect an act will have on the world depends not only (...) on which acts the agent will simultaneously and subsequently perform, but also on which attitudes she will simultaneously and subsequently form. And this all leads me to adopt a new type of practical theory, which I call rational possibilism. On this theory, we first evaluate the entire set of things over which the agent exerts control, where this includes the formation of certain attitudes as well as the performance of certain acts. And, then, we evaluate individual acts as being permissible if and only if, and because, there is such a set that is itself permissible and that includes that act as a proper part. Importantly, this theory has two unusual features. First, it is not exclusively act-orientated, for it requires more from us than just the performance of certain voluntary acts. It requires, in addition, that we involuntarily form certain attitudes. Second, it is attitude-dependent in that it holds that which acts we’re required to perform depends on which attitudes we’re required to form. I then show how these two features can help us both to address certain puzzling cases of rational choice and to understand why most typical practical theories (utilitarianism, virtue ethics, rational egoism, Rossian deontology, etc.) are problematic.

In an influential paper, James Lenman argues that consequentialism can provide no basis for ethical guidance, because we are irredeemably ignorant of most of the consequences of our actions. If our ignorance of distant consequences is great, he says, we can have little reason to recommend one action over another on consequentialist grounds. In this article, I show that for reasons to do with statistical theory, the cluelessness objection is too pessimistic. We have good reason to believe that certain patterns (...) of action will tend to have better consequences, and we have good reason to recommend acting in accordance with strategies based on those advantageous patterns. I close by saying something about the strategies that this argument should lead us to favour. (shrink)

How ought you to evaluate your options if you're uncertain about what's fundamentally valuable? A prominent response is Expected Value Maximisation (EVM)—the view that under axiological uncertainty, an option is better than another if and only if it has the greater expected value across axiologies. But the expected value of an option depends on quantitative probability and value facts, and in particular on value comparisons across axiologies. We need to explain what it is for such facts to hold. Also, EVM (...) is by no means self-evident. We need an argument to defend that it’s true. This book introduces an axiomatic approach to answer these worries. It provides an explication of what EVM means by use of representation theorems: intertheoretic comparisons can be understood in terms of facts about which options are better than which, and mutatis mutandis for intratheoretic comparisons and axiological probabilities. And it provides a systematic argument to the effect that EVM is true: the theory can be vindicated through simple axioms. The result is a formally cogent and philosophically compelling extension of standard decision theory, and original take on the problem of axiological or normative uncertainty. (shrink)

The topic of this thesis is axiological uncertainty – the question of how you should evaluate your options if you are uncertain about which axiology is true. As an answer, I defend Expected Value Maximisation (EVM), the view that one option is better than another if and only if it has the greater expected value across axiologies. More precisely, I explore the axiomatic foundations of this view. I employ results from state-dependent utility theory, extend them in various ways and interpret (...) them accordingly, and thus provide axiomatisations of EVM as a theory of axiological uncertainty.

This paper faces the problem of how to determinate the framework in which, according to Aristotle, the deliberation and his results can be assessed: the decision and the consequent action. The problem emerges mainly because of what Aristotle calls “indetermination of deliberation,” since, in situations whose options about what to deliberate are blurred, it is difficult to determinate which is the framework that can be used to determinate if the decision resulting from the deliberation is accurate or not. To face (...) this problem, in the first place, we distinguish between technical and moral deliberation. The distinction is framed in terms of the ends because in technical deliberation the end is extrinsic to the action itself, and for this reason it is possible to offer different assessments of the actions achieved. In moral deliberation, the ends are only intrinsic to the action, and they are determined only in behalf of their connection with good deliberation. So, it is only possible to establish an adequate normative framework to assess each deliberation based upon a “good deliberation model”, established by practical wisdom, and extended also for the community from which the subject takes part.

Maximalism is the view that an agent is permitted to perform a certain type of action if and only if she is permitted to perform some instance of this type, where φ-ing is an instance of ψ-ing if and only if φ-ing entails ψ-ing but not vice versa. Now, the aim of this paper is not to defend maximalism, but to defend a certain account of our options that when combined with maximalism results in a theory that accommodates the idea (...) that a moral theory ought to be morally harmonious—that is, ought to be such that the agents who satisfy the theory, whoever and however numerous they may be, are guaranteed to produce the morally best world that they have the option of producing. I argue that, for something to count as an option for an agent, it must, in the relevant sense, be under her control. And I argue that the relevant sort of control is the sort that we exercise over our reasons-responsive attitudes by being both receptive and reactive to reasons. I call this sort of control rational control, and I call the view that φ-ing is an option for a subject if and only if she has rational control over whether she φs rationalism. When we combine this view with maximalism, we get rationalist maximalism, which I argue is a promising moral theory. (shrink)

I discuss Bernard Williams’ ‘integrity objection’ – his version of the demandingness objection to unreasonably demanding ‘extremist’ moral theories such as consequentialism – and argue that it is best understood as presupposing the internal reasons thesis. However, since the internal reasons thesis is questionable, so is Williams’ integrity objection. I propose an alternative way of bringing out the unreasonableness of extremism, based on the notion of the agent’s autonomy, and show how an objection to this proposal can be outflanked by (...) a strategy that also outflanks the ‘paradox of deontology.’.

The book concerns what I take to be the least controversial normative principle concerning action: you ought to perform your best option—best, that is, in terms of whatever ultimately matters. The book sets aside the question of what ultimately matters so as to focus on more basic issues, such as: What are our options? Do I have the option of typing out the cure for cancer if that’s what I would in fact do if I had the right intentions at (...) the right times (e.g., the intention to type the letter T at t1, the intention to type the letter H at t2, the intention to type the letter E at t3, etc.)? If I can’t form intentions voluntarily, does that mean that I don’t have the option of forming the intention that I ought to form? Which options do we assess directly in terms of their own goodness and which do we assess in terms of their relations to the goodness of other options? What do we hold fixed when assessing how good an option is? Do we, for instance, hold fixed the agent’s future beliefs, desires, and intentions? And do we hold fixed the agent’s predictable future misbehavior? Lastly, how do the things that ultimately matter determine the goodness of an option? If one of the things that ultimately matters in determining the goodness of an option is that the option doesn’t involve violating anyone’s rights, do we evaluate the option itself in terms of whether it involves violating anyone’s rights or do we evaluate the option’s prospect in terms of this and then the option in terms of its prospect? And what if there is indeterminacy or uncertainty with regards to whether an option would involve violating someone’s rights? (shrink)

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)

Two meanings of "subjective consequentialism" are distinguished: conscious deliberation with the aim of producing maximally-good consequences, versus acting in ways that, given one's evidence set and reasoning capabilities, is subjectively most likely to maximize expected consequences. The latter is opposed to "objective consequentialism," which demands that we act in ways that actually produce the best total consequences. Peter Railton's arguments for a version of objective consequentialism confuse the two subjective forms, and are only effective against the first. After reviewing the (...) arguments of Eric Wiland and Frances Howard-Snyder against objective consequentialism, two of Railton's arguments which might seem to count against the second form of subjective consequentialism are shown to be ineffective. This leaves subjective consequentialism as a viable theory to replace objective consequentialism with. (shrink)
