David Hume famously criticized rationalist theories of practical reason, arguing that reason alone is incapable of yielding action, and that some passionate element must be supplied. Contemporary theories of Humean inspiration develop a causal-explanatory model of action in terms of the joint operation of two distinct mental states: beliefs and desires, one inert and representational, the other dynamic. Such neo-Humean theories claim that since desires, unlike beliefs, are not subject to direct rational evaluation, an act can be said to be rational only in the sense that it is instrumental to realizing the agent’s desires. The historical Hume appears to have embraced a “sceptical solution” involving a more dynamic conception of belief, while admitting a default sense in which both beliefs and actions can be deemed reasonable or unreasonable.

Although the ‘naturalistic fallacy’ and the is/ought distinction have often been invoked as definitive grounds for rejecting any attempt to bring evolutionary thought to bear on ethics, they are better interpreted as warnings than as absolute barriers. Our moral concepts themselves -- e.g. the principle that ‘ought implies can’ -- require us to ask whether human psychology is capable of impartial empathetic thought and motivation characteristic of normative systems that could count as moral. As the essay by Flack and de Waal shows, evolutionary theory and evidence can help us answer the question whether the psychological ‘building blocks’ needed for morality are indeed likely to be present in a given species, including Homo sapiens. It is important, however, not to think that a positive answer to this question commits us to attributing identifiable moral concepts to actual members

It has been the dominant view that probabilistic explanations of particular facts must be inductive in character. I argue here that this view is mistaken, and that the aim of probabilistic explanation is not to demonstrate that the explanandum fact was nomically expectable, but to give an account of the chance mechanism(s) responsible for it. To this end, a deductive-nomological model of probabilistic explanation is developed and defended. Such a model has application only when the probabilities occurring in covering laws can be interpreted as measures of objective chance, expressing the strength of physical propensities. Unlike inductive models of probabilistic explanation, this deductive model stands in no need of troublesome requirements of maximal specificity or epistemic relativization

Marx claims that his social theory is objective in the same sense as contemporary natural science. Yet his social theory appears to imply that the prevailing notion of scientific objectivity is ideological in character. Must Marx, then, either give up his claim of scientific objectivity or admit that he is engaged in a bit of ideology on behalf of his own theory? By suggesting an alternative way of understanding objectivity, an attempt is made to show that one can accept the implications of Marx's social theory and yet still hold that scientific inquiry is objective in an epistemically appropriate sense--not in spite of, but in large measure because of, the role Marx assigns science within the capitalist division of labor.

In our everyday lives we struggle with the notions of why we do what we do and the need to assign values to our actions. Somehow, it seems possible through experience and life to gain knowledge and understanding of such matters. Yet once we start delving deeper into the concepts that underwrite these domains of thought and actions, we face a philosophical disappointment. In contrast to the world of facts, values and morality seem insecure, uncomfortably situated, easily influenced by illusion or ideology. How can we apply this same objectivity and accuracy to the spheres of value and morality? In the essays included in this collection, Peter Railton shows how a fairly sober, naturalistically informed view of the world might nonetheless incorporate objective values and moral knowledge. This book will be of interest to professionals and students working in philosophy and ethics.

Although the standard theory and actual practice of cost-benefit analysis are seriously defective, the general idea of making social policy in accord with an aggregative, maximizing, consequentialist criterion is a sensible one. Therefore it is argued, against Bantz, that interpersonal utility comparisons can be meaningful, and, against both Bantz and MacLean, that quantitative overall assessments of expected value provide a presumptively rational basis for social choice. However, it does not follow that introducing cost-benefit tests into the political or legal process would always be optimal: recognizing some quite stringent legal rights against involuntary exposure to pollution or risk may actually promote cost-beneficial results more reliably than cost-benefit tests employed in very imperfect circumstances

I’ve been told that there are two principal approaches to drawing figures from life. One begins by tracing an outline of the figure to be drawn, locating its edges and key features on an imagined grid, and then using perspective to fill in depth. The other approach proceeds from the ‘center of mass’ of the subject, seeking to build up the image by supplying contour lines, the intersections of which convey depth—as if the representation were being created in relief. The second approach need not adopt a unified perspective, and is more concerned with evoking the volume and ‘presence’ of the subject than with accurate placement of edges and features. Call this second approach drawing ‘from the inside out’, meant to capture the living force of the subject rather than freeze it in a coordinate frame.

Statements about a person's good slip into and out of our ordinary discourse about the world with nary a ripple. Such statements are objects of belief and assertion, they obey the rules of logic, and they are often defended by evidence and argument. They even participate in common-sense explanations, as when we say of some person that he has been less subject to wild swings of enthusiasm and disappointment now that, with experience, he has gained a clearer idea of what is good for him. Statements about a person's good present themselves as being about something with respect to which our beliefs can be true or false, warranted or unwarranted. Let us speak of these features as the descriptive side of discourse about a person's good

Traditional virtue-oriented approaches to ethics suppose that acquiring relatively stable character traits, such as courage and compassion, is crucial in addressing the question of how to be. However, recent psychological studies cast doubt on the idea that people develop such traits. In light of this pessimism, the paper raises the question: what is left of virtue theory? It argues that much remains once one shifts from a traditional understanding of virtues to one of cognitive/affective “if…then” dispositions that form a person’s character. The central proposal is to understand such dispositions as “habitudes” – habitual ways of thinking, feeling, and acting that are acquired by example and repetition, and that enable one to competently react to varying situations one confronts. The resulting model of ethical comportment represents a psychologically realistic understanding of virtue. Furthermore, this account fits well with what we learn from the field of positive psychology about subjective well-being, thus helping to vindicate eudaimonism.
