Those who criticize as well as those who nowadays defend constructivism in metaethics consider John Rawls’s constructivism to be incomplete. According to them, his ontological agnosticism makes evident this incompleteness; I question this widely accepted charge. I propose an alternative interpretation, according to which Rawls’s agnosticism is the effect of his metaethics rather than a lack of metaethics. Thanks to this interpretation, I question the originality and attractiveness of Rawls’s metaethics. My claim is that Rawls’s metaethics adequately captures the specific (...) historical nature of political norms. (shrink)

Je défends dans ce texte une version particulière de la position que Sharon Street a appelée le «constructivisme humien». J’esquisserai pourquoi je considère que ce constructivisme est préférable à la fois au réalisme moral et au constructivisme kantien sur le plan de la compréhension du statut ontologique des valeurs. Après avoir accepté de reconnaître le rôle des pressions de l’évolution dans l’émergence de la moralité, le constructivisme humien doit toutefois préciser le rôle de l’intersubjectivité historique dans l’évolution subséquente de la (...) morale. J’expliquerai aussi pourquoi je considère que l’intégration d’un volet cohérentiste au constructivisme permet d’atténuer les craintes concernant le caractère potentiellement non-cognitiviste des théories contextualistes. Enfin, j’esquisserai pourquoi l’idée d’un «espace des raisons morales» indépendant, à certains égards, de l’esprit humain est compatible avec le constructivisme humien.I defend a version of what Sharon Street has dubbed “Humean constructivism.” I’ll first sketch out why I think that contextual constructivism provides us with a more plausible understanding of the ontological status of values than both Kantian constructivism and moral realism. In addition to its recognition of the role of evolutionary pressures in the emergence of human morality, contextual constructivism must now clarify the role of historical intersubjectivity in the subsequent development of morality. I will then claim that adding a coherentist module to Humean constructivism provides a satisfactory answer to those who fear that contextual metaethical theories can only be non-cognitivist. Finally, I will sketch out why I think that the notion of a mind-independent “space of moral reasons” is largely compatible with Humean constructivism. (shrink)

In this paper, I reply to Sharon Street’s objection against quasi-realism, according to which this theory is subject to a problem of unexplained coincidence between the normative truths and our evaluative attitudes. I argue that this problem cannot be applied to quasi-realism because the necessary element for it to be applied is missing in this theory: an ontological commitment towards robust normative entities. This lack of commitment allows quasi-realists to argue for a minimalist conception of normative truths, and to escape (...) the scope of the problem of unexplained coincidence. (shrink)

We argue that Reasons Fundamentalism, as defended by T.M. Scanlon, faces two important difficulties—one ontological, the other epistemological—namely theontological proliferation problemand thereliability challenge.We suggest that formal constructivism can avoid these difficulties, and that Scanlon would do well to adopt it. We also show that Scanlon’s three main objections to this view depend either on a misunderstanding of what formal constructivism is or on a question-begging argument in favour of realism.
