Moral realismandantirealist-expressivismare 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, acognitivestate of mind; she has or expresses abeliefthat 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, aconativestate 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. (shrink)

ABSTRACT: David Braybrooke argues that the core of the natural law theory of Thomas Aquinas survived in the work of Hobbes, Locke, Hume, and Rousseau. Much to my surprise, Braybrooke argues as well that David Copp’s society-centered moral theory is a secular version of this same natural law theory. Braybrooke makes a good case that there is an important idea about morality that is shared by the great philosophers in his group and that this idea is also found in Copp’s (...) work. The idea is captured by the Functionalist Thesis, the thesis that moral propositions are made true by facts about what, given the nature of human beings and their circumstances, enables people to live together in thriving communities. I argue that Copp can accept Braybrooke’s suggestion and use it to improve his formulation of the basic idea of the society-centered theory. RÉSUMÉ : David Braybrooke soutient que l’idée centrale de la théorie du droit naturel de Thomas d’Aquin a survécu dans les œuvres de Hobbes, Locke, Hume et Rousseau. À mon grand étonnement, Braybrooke soutient aussi que la théorie morale société-centrique de David Copp est une version séculaire de cette même théorie du droit naturel. Braybrooke argumente de façon convaincante que les œuvres de ces grands philosophes partagent une idée centrale relative à la moralité et que cette idée se retrouve aussi chez Copp. Cette idée est la Thèse Fonctionnaliste, c’est-à-dire la thèse selon laquelle les faits moraux sont des faits concernant ce qui rend les membres de la société capables de vivre ensemble dans des communautés florissantes, étant donné la nature des êtres humains et les circonstances de leurs vies. Je soutiens que Copp peut reprendre à son compte les arguments de Braybrooke, et ainsi améliorer la formulation de l’idée centrale de sa théorie société-centrique. (shrink)

Ethical naturalism is the doctrine that moral properties, such as moral goodness, justice, rightness, wrongness, and the like, are among the “natural” properties that things can have. It is the doctrine that moral properties are “natural” and that morality is in this sense an aspect of “nature.” Accordingly, it is a view about the semantics and metaphysics of moral discourse. For example, a utilitarian naturalist might propose that wrongness is the property an action could have of being such as to (...) undermine overall happiness, where happiness is taken to be a psychological property. Unfortunately, it is unclear what the naturalist means by a “natural” property. For my purposes in this paper, I shall assume that natural properties are such that our knowledge of them is fundamentally empirical, grounded in observation. More precisely, a property is “natural” just in case any synthetic proposition about its instantiation can be known onlya posteriori,or with the aid of experience. (shrink)
