Moral dilemmas have long been debated in moral philosophy without reaching a definitive consensus. The majority of value pluralists attribute their origin to the incommensurability of moral values, i.e. the statement that, since moral values are many and different in nature, they may conflict and cannot be compared. Neuroscientific studies on the neural common currency show that the comparison between allegedly incompatible alternatives is a practical possibility, namely it is the basis of the way in which the agent evaluates choice (...) options. Indeed, both in economic and moral decision-making, the value of options is represented and directly compared in the ventromedial prefrontal cortex. Therefore, we contend that moral dilemmas do not originate from value incommensurability and, on the basis of the neuroscientific discoveries on the neural currency, we derive the implications for the philosophical debate on moral dilemmas. We also provide a possible connection between the experience of moral dilemmas and their neural representation: one of the causes of the individual’s indecision is the neural tie, i.e. the condition in which two options have the same value at neural level, and her regret could be due to the motivational force of the rejected option that is still signalled by affective processes in the brain. We apply this interpretation and the common currency hypothesis to vocational decisions and propose that, although from the agent’s perspective the options are qualitatively different, they may be nevertheless equivalent at neural level. This can be seen as a reason for downgrading the importance commonly attributed to the risk of making the “wrong choice”. (shrink)

In this paper, I argue that those moral theorists who wish to accommodate agent-centered options and supererogatory acts must accept both that the reason an agent has to promote her own interests is a nonmoral reason and that this nonmoral reason can prevent the moral reason she has to sacrifice those interests for the sake of doing more to promote the interests of others from generating a moral requirement to do so. These theorists must, then, deny that moral reasons morally (...) override nonmoral reasons, such that even the weakest moral reason trumps the strongest nonmoral reason in the determination of an act’s moral status (e.g., morally permissible or impermissible). If this is right, then it seems that these theorists have their work cut out for them. It will not be enough for them to provide a criterion of rightness that accommodates agent-centered options and supererogatory acts, for, in doing so, they incur a debt. As I will show, in accommodating agent-centered options, they commit themselves to the view that moral reasons are not morally overriding, and so they owe us an account of how both moral reasons and nonmoral reasons come together to determine an act’s moral status.

Can we understand being valuable for in terms of being valuable? Three different kinds of puzzle cases suggest that the answer is negative. In what follows, I articulate a positive answer to this question, carefully present the three puzzle cases, and then explain how a friend of the positive answer can successfully respond to them. This response requires us to distinguish different kinds of value bearers, rather than different kinds of value, and to hold that among the value bearers are (...) totality states of affairs. The final section of the article discusses the possibility of organic unification without organic unities. (shrink)

Several critics have denied value incommensurability – or the claim, roughly, that there is no common measure in terms of which values can be weighed – on the basis of what we might call the argument from easy cases. Although the argument from easy cases is quite popular, what is much less often discussed is what exactly the argument entails – in other words, what sort of further commitments the argument generates. Suppose we grant that easy cases point to the (...) existence of a common measure. How then should we think about this common measure? What is its scope? How widely does it range? I attempt to clarify these questions and in the process evaluate the force of the argument from easy cases. (shrink)

A dogma of contemporary normative theorizing holds that some reasons are distinctively moral while others are not. Call this view Reasons Pluralism. This essay looks at four approaches to vindicating the apparent distinction between moral and non-moral reasons. In the end, however, all are found wanting. Though not dispositive, the failure of these approaches supplies strong evidence that the dogma of Reasons Pluralism is ill-founded.

This introductory article describes the phenomena of incommensurability and incomparability, how they are related, and why they are important. Since incomparability is the more significant phenomenon, the paper takes that as its focus. It gives a detailed account of what incomparability is, investigates the relation between the incomparability of values and the incomparability of alternatives for choice, distinguishes incomparability from the related phenomena of parity, indeterminacy, and noncomparability, and, finally, defends a view about practical justification that vindicates the importance of (...) incomparability — assuming it exists — for practical reason.

This article explores the main similarities and differences between Derek Parfit’s notion of imprecise comparability and a related notion I have proposed of parity. I argue that the main difference between imprecise comparability and parity can be understood by reference to ‘the standard view’. The standard view claims that 1) differences between cardinally ranked items can always be measured by a scale of units of the relevant value, and 2) all rankings proceed in terms of the trichotomy of ‘better than’, (...) ‘worse than’, and ‘equally good’. Imprecise comparability, which can be understood in terms of the more familiar notions of cardinality and incommensurability, rejects only the first claim while parity rejects both claims of the standard view. -/- I then argue that insofar as those attracted to imprecise comparability assume that all rankings are trichotomous, as Parfit appears to, the view should be rejected. This is because imprecise equality is not a form of equality but is a sui generis ‘fourth’ basic way in which items can be ranked. We should, I argue, understand imprecise equality as parity, and imprecise comparability as entailing ‘tetrachotomy’ – that if two items are comparable, one must better than, worse than, equal to, or on a par with the other. Thus those attracted to the idea that cardinality can be imprecise should abandon trichotomy and accept parity and tetrachotomy instead. -/- Finally, I illustrate the difference between Parfit’s trichotomous notion of imprecise comparability and parity by examining how each notion might be employed in different solutions to the problem posed by the Repugnant Conclusion in population ethics. I suggest that parity provides the arguably more ecumenical solution to the problem. (shrink)

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers.".

Overview of the main issues about value pluralism.

In this paper, I present an argument that poses the following dilemma for moral theorists: either (a) reject at least one of three of our most firmly held moral convictions or (b) reject the view that moral reasons are morally overriding, that is, reject the view that moral reasons override non-moral reasons such that even the weakest moral reason defeats the strongest non-moral reason in determining an act’s moral status (e.g., morally permissible). I then argue that we should opt for (...) the second horn of this dilemma, in part because we should be loath to reject such firmly held moral convictions, but also because doing so allows us to dissolve an apparent paradox regarding supererogation. If I’m right, if non-moral reasons are relevant to determining what is and isn’t morally permissible, then it would seem that moral theorists have their work cut out for them. Not only will they need to determine what the fundamental right-making and wrong-making features of actions are (i.e., what moral reasons there are), but they will also need to determine what non-moral reasons there are and which of these are relevant to determining an act’s deontic status. And moral theorists will have to account for how these two very different sorts of reasons—moral and non-moral reasons—”come together” to determine an act’s deontic status. I will not attempt to do this work here, but rather only to argue that the work needs to be done. (shrink)
