James Lenman, University of Sheffield : « The politic of objectivity »


My project is to defend a modest possiblity claim. I think there could be a community of rational reasonable social animals who lived together in moral community regulating their lives by a complex system of broadly shared norms and values which they affirmed and adhered to. And I think it is possible for there to be such a community in a world in which the semantic, metaphysical and epistemological claims of robust moral realists were all false without the members of that community consequently falling into any errors or being subject to any illusions. If this possibility claim is true, that would, I take it, be dialectically rather bad news for those semantic, metaphysical and epistemological claims.

Olivier Massin, CNRS/ Université de Zurich : « Grounding the normative »


There is a large consensus to the effect normative features (moral, legal, aesthetic, epistemic…) are somehow necessitated by and  grounded in (i.e. explained by) non-normative ones (psychological, psychological, social…). The consensus cracks, however, when one tries to spell out how exactly normative features are so necessitated/grounded. One main recent locus of disagreement is found in the debate over whether the necessitation/grounding relation at stake is metaphysical, or constitutes a new sui generis form of normative necessitation/grounding. After having given an overview of that debate, I shall suggest that, depending on the cases, they are in fact many different ways in which the normative is necessitated by and grounded in the natural, so that looking for a single account of the necessitation/grounding relations between the natural and the normative may lead us astray.

Michele Palmira , University of Barcelona & LOGOS Research Group : "How to Respond Rationally to Moral Disagreement"

In this talk I tackle the question of how we should respond to moral disagreement with our acknowledged epistemic peers. In the first part of the talk I examine and criticise two answers to this question: the conciliatory answer maintaining that we should suspend judgement, and the steadfast answer claiming that we should retain our beliefs. My main line of criticism is developed around the idea that both answers fail to appreciate the multifaceted nature of moral disagreement. In the second part of the talk I outline a third-way answer, which hinges on two main contentions. First, disagreement is evidence which should lead the peers to re-assess their epistemic position vis-à-vis the issue at stake. Secondly, this re-assessment, which can result in various outcomes depending on the specific disagreement case at stake, can be rationally carried out while entertaining a sui generis doxastic attitude which I call “hypothesis”. In the third part of the talk I test my third-way answer against various cases of moral disagreement in order to show that it fares better than its conciliatory and steadfast rivals.
