This paper is a survey of the generalism-particularism debate in ethics. It's an updated version of "Moral Particularism", in Christian B. Miller (ed.), The Continuum Companion to Ethics (Continuum, 2011), pp. 247-260.

It may be a myth that Plato wrote over the entrance to the Academy “Let no-one ignorant of geometry enter here.” But it is a well-chosen motto for his view in the Republic that mathematical training is especially productive of understanding in abstract realms, notably ethics. That view is sound and we should return to it. Ethical theory has been bedevilled by the idea that ethics is fundamentally about actions (right and wrong, rights, duties, virtues, dilemmas and so on). That (...) is an error like the one Plato mentions of thinking mathematics is about actions (of adding, constructing, extracting roots and so on). Mathematics is about eternal relations between universals, such as the ratio of the diagonal of a square to the side. Ethics too is about eternal verities, such as the equal worth of persons and just distributions. Mathematical and ethical verities do both constrain actions, such as the possibility of walking over the seven bridges of Königsberg once and once only or of justly discriminating between races. But they are not themselves about action. In principle, neither mathematical nor ethical verities are subject to historical forces or disagreement among tribes (though they can be better understood as time goes on). Plato is right: immersion in mathematics induces an understanding of the necessities underpinning reality, an understanding that is essential for distinguishing objective ethics from tribal custom. Equality, for example, is an abstract concept which is foundational for both mathematics and ethics. (shrink)

Does immorality necessarily involve irrationality? The question is often taken to be among the deepest in moral philosophy. But apparently deep questions sometimes admit of deflationary answers. In this case we can make way for a deflationary answer by appealing to dualism about rationality, according to which there are two fundamentally distinct notions of rationality: structural rationality and substantive rationality. I have defended dualism elsewhere. Here, I’ll argue that it allows us to embrace a sensible – I will not say (...) boring – moderate view about the relationship between immorality and irrationality: roughly, that immorality involves substantive irrationality, but not structural irrationality. I defend this moderate view, and argue that many of the arguments for less moderate views turn either on missing the distinction between substantive and structural rationality, or on misconstruing it.

In both the early modern period and in contemporary debates, philosophers have argued that there are analogies between mathematics and morality that imply that the ontology and epistemology of morality are crucially similar to the ontology and epistemology of mathematics. I describe arguments for the math‐moral analogy in four early modern philosophers (Locke, Cudworth, Clarke, and Balguy) and in three contemporary philosophers (Clarke‐Doane, Peacocke, and Roberts). I argue that these arguments fail to establish important ontological and epistemological similarities between morality (...) and mathematics. There are analogies between the two areas, but the disanalogies are more significant, undermining the attempt to confer on morality the same ontological and epistemological status that mathematics possesses.

Darwin’s treatment of morality in The Descent of Man has generated a wide variety of responses among moral philosophers. Among these is the dismissal of evolution as irrelevant to ethics by Darwin’s contemporary Henry Sidgwick; the last, and arguably the greatest, of the Nineteenth Century British Utilitarians. This paper offers a re-examination of Sidgwick’s response to evolutionary considerations as irrelevant to ethics and the absence of any engagement with Darwin’s work in Sidgwick’s main ethical treatise, The Methods of Ethics . (...) This assessment of Sidgwick’s response to Darwin’s work is shown to have significance for a number of ongoing controversies in contemporary metaethics. (shrink)

This paper is a survey of the generalism-particularism debate in ethics.

Non-descriptivists in metaethics should say more about intuitions. For one popular theory has it that case-based intuitions are in the business of correctly categorizing or classifying merely by bringing to bear a semantic or conceptual competence. If so, then the fact that all normative predicates have case-based intuitions involving them shows that they too are in the business of categorizing or classifying things. This favors a descriptivist position in metaethics—normative predicates have descriptive content—and disfavors a purely non-descriptivist position, like pure (...) expressivism. However, we can say more. We can distinguish two different sorts of intuitional state, A-grade intuitions and B-grade intuitions, based on a cluster of properties that are distinctive of each. While a hypothesis about categorization best explains the cluster of properties enjoyed by A-grade intuitions, it does not best explain the cluster of properties enjoyed by B-grade intuitions. Indeed, a non-categorizational, attitude-expressive hypothesis about the relevant meanings best explains B-grade intuitions. And intuitions involving thin normative predicates are B-grade. So intuition theory supports non-descriptivism, not descriptivism, about thin normative predicates. (shrink)

The paper examines three tenets of Dancy’s meta-ethics, finds them incompatible, and proposes a response-dependentist (or response-dispositional) solution. The first tenet is the central importance of thick concepts and properties. The second is that such concepts essentially involve response(s) of observers, which Dancy interprets in a way that fits the pattern of context-dependent resultance: thick concepts are well suited for the particularist grounding of moral theory. However, and this is the third tenet, in his earlier paper (1986) Dancy forcefully argues (...) against response-dispositional accounts of moral concepts and properties. The present paper argues that an anti-dispositional view is incompatible with the first two points concerning thick concepts. If thick concepts and properties are paramount and ubiquitous in moral thought and reality, and if they are essentially tied to human responses, then anti-dispositionalism is false. Dancy himself avoids obvious contradiction by characterizing thick items (concepts) differently from the usual characterization of response-dependent items. Actions that satisfy thick concepts do so in virtue of meriting a determinate response. The (non-reductionist) response-dependentist usually puts it slightly differently: such actions satisfy a given moral concepts in virtue of eliciting a merited response. I have argued at length that this tenuous difference in formulation is too weak to support a relevant difference in rebus. If the argument is right, Dancy is implicitly committed to a kind of response-dependentism. Finally, the particularist should embrace thick concepts and properties, and reject anti-dispositionalism. However, this would bring back the analogy with color and other secondary qualities. Since there are ceteris paribus laws governing such properties, the analogy suggests that moral properties might also be best accounted for by a ceteris paribus, or hedged account, a compromise between traditional generalism and the particularism of Dancy’s variety.

This paper is a response to Niklas Möller’s (Philosophical Studies, 2013) recent criticism of our relational (Jazz) model of meaning of thin evaluative terms. Möller’s criticism rests on a confusion about the role of coordinating intentions in Jazz. This paper clarifies what’s distinctive and controversial about the Jazz proposal and explains why Jazz, unlike traditional accounts of meaning, is not committed to analycities.
