The present text aims to make an examination of the varieties of moral naturalism, and for this it will examine some anti-naturalist and anti-realist arguments. It will also argue that existent theories can be considered on two dimensions, the metaphysical and epistemological dimension, and the dimension of motivation and normativity. In the first dimension, there is non-reductive naturalism and reductive naturalism of the non-analytic variety. Turning to the second dimension, the dimension of normativity and moral motivation, we find internalist naturalism, simple externalist naturalism and externalist naturalism with the standard-based account of normativity. At the end, the text will say something in favor of moral realism and to a kind of naturalism in specific. Key words: moral naturalism, normativity, moral realism, moral non-realism.

Moral claims not only purport to be true, they also purport to guide our choices. This book presents a new theory of normative judgment, the "standard-based theory," which offers a schematic account of the truth conditions of normative propositions of all kinds, including moral propositions and propositions about reasons. The heart of Copp 's approach to moral propositions is a theory of the circumstances under which corresponding moral standards qualify as justified, the " society -centered theory." He argues that because any society needs a social moral code in order to enable its members to live together successfully, and because it would be rational for a society to choose such a code, certain moral codes, and the standards they include, are justified. According to the standard-based theory then, if certain moral standards are indeed justified, corresponding moral propositions may be true. Copp 's approach to morality and explaining normativity and the truth conditions of moral claims, raises a number of important issues in moral theory, as well as in metaphysics and the philosophy of language.

The “ultimate objective” of this book, says David Schmidtz, “is to examine the degree to which being moral is co-extensive with being rational”. For Schmidtz, an “end” gives us a reason for action provided that its pursuit is not undercut by some other end. Morality has a two-part structure. A person’s goal is “moral” if “pursuing it helps [her] to develop in a reflectively rational way,” provided its pursuit does not violate “interpersonal moral constraints”. Interpersonal constraints are imposed by “collectively rational” social institutions, institutions that “make people in general better off by nonexploitative means”. Schmidtz’s view is a form of “actualism.” Our reasons are given by our actual goals, subject to the qualification mentioned above, and moral constraints are given by actually existing collectively rational institutions. Schmidtz concedes that this framework cannot guarantee that it is rational for every agent to be moral, and he concedes that his moral theory might be incomplete. Nevertheless, he argues, “morality and rationality make room for each other in a variety of ways”.

According to the principle of alternate possibilities (PAP), a person is morally responsible for an action only if he could have done otherwise. PAP underlies a familiar argument for the incompatibility of moral responsibility with determinism. I argue that Harry Frankfurt's famous argument against PAP is unsuccessful if PAP is interpreted as a principle about blameworthiness. My argument turns on the maxim that "ought implies can" as well as a "finely-nuanced" view of the object of blame. To reject PAP on the blameworthiness interpretation, we must reject either this maxim or the finely-nuanced view or some other apparently innocuous assumption.

The Problem Economic efficiency is naturally thought to be a virtue of social policies and decisions, and cost-benefit analysis is commonly regarded as a technique for measuring economic efficiency. It is not surprising, then, that CB analysis is so widely used in social policy analysis. However, there is a great deal of controversy about CB analysis, including controversy about its underlying philosophical rationale. The rationales that have been proposed fall into three basic, though not mutually exclusive categories. There are moralist views to the effect that an acceptable CB analysis would provide, or contribute to, an ethical appraisal of proposed policies or projects. There are rationalist views to the effect that an acceptable CB analysis would contribute to the selection of social policies and projects that are “socially rational.” Finally, there are so-called management science views to the effect that the purpose of CB analysis is to promote the achievement of objectives held by the policy maker, whatever they may be. Different positions are available within each of these categories. But there is also the possibility that CB analysis lacks any viable rationale. I will examine some of the major rationales for CB analysis in this paper, and I will suggest that the last view is close to the truth.

Moral realism and antirealist-expressivism are of course incompatible positions. They disagree fundamentally about the nature of moral states of mind, the existence of moral states of affairs and properties, and the nature and role of moral discourse. The central realist view is that a person who has or expresses a moral thought is thereby in, or thereby expresses, a cognitive state of mind; she has or expresses a belief that represents a moral state of affairs in a way that might be accurate or inaccurate. The view of antirealist-expressivism is that such a person is in, or expresses, a conative state of mind, one that consists in a certain kind of attitude or motivational stance toward something, such as an action or a person. Realism holds that moral thoughts have truth conditions and that in some cases these truth conditions are satisfied so that our moral thoughts are true. Antirealist-expressivism holds, to a first approximation, that the distinctive moral content of a moral thought does not have truth conditions

This paper is a reply to Anton Leist’s criticisms of the view I develop in my book, Morality, Normativity, and Society. Leist claims that my “standard-based” account of the truth conditions of moral propositions is incoherent. I argue that he is mistaken about this. Leist claims that my “society-centered” account of the justification of moral standards has “nasty” implications. In the course of answering this worry, I develop the idea of a “moral necessity”. My theory implies that although moral propositions are metaphysically contingent, they are most likely morally necessary. I also explain that, despite its relativism, the society-centered view is quite compatible with the idea that there are certain “moral universals”. Finally, Leist claims that the arguments I have given in favor of my view are unsuccessful. But it is a mistake to think that decisive arguments can be expected in this area. The most we can expect is a clear statement of the costs and benefits of a theory. I claim that my account of the nature and grounding of morality has important advantages over familiar alternatives.

An account of the ontological nature of collectives would be useful for several reasons. A successful theory would help to show us a route through the thicket of views known as “methodological individualism”. It would have a bearing on the plausibility of legal positivism. It would be relevant to the question whether collectives are capable of acting. The debate about the ontology of collectives is therefore important for such fields as the theory of action, social and political philosophy, the philosophy of law and the philosophy of social science. I hope to contribute to the debate by proposing an account of collectives, and by showing its theoretical soundness and utility. In its essentials, my proposal is that collectives are “mereological sums” of “stages” of persons linked by a “unity relation”. The influence on this account of some theories of personal identity will perhaps be obvious. But the motivation is different, for it lies at least as much in the ability of the theory to help us deal with the issues already mentioned as in problems concerning the identity of collectives over time. I acknowledge that my proposal is not commonsensical; however, I believe that no account could be both commonsensical and adequate. I will begin by introducing some constraints on a theory of collectives.

According to the basic needs principle, a state in favorable circumstances must enable its members to meet their basic needs throughout a normal life-span. Applied to the international situation, I argue, this principle implies that a global state would have a duty (ceteris paribus) to enable subordinate states to meet their members‘ needs. In the absence of a global state, existing states have a duty (ceteris paribus) to work to create a system of institutions that would enable each state to meet its members‘ needs. Near the conclusion, I respond to skeptical objections about global justice.
