Selon certains philosophes, le principe « devoir-implique-pouvoir » exprime une vérité analytique et permet d’inférer des énoncés normatifs sur la base de prémisses purement descriptives. Le principe DIP offrirait ainsi un contre-exemple à la fameuse loi de Hume. Le problème est que DIP permet uniquement de construire des raisonnements dont les conclusions sont des négations de normes. Or, selon certains auteurs, les négations de normes n’expriment pas de véritables jugements moraux. En ce sens, selon eux, DIP ne permet pas de (...) tirer des conclusions normatives sur la base de prémisses uniquement descriptives. Dans cet article, nous soutenons au contraire que les négations de normes sont de véritables normes et que DIP permet bien de déduire une conclusion normative à partir de prémisses purement descriptives.

This paper attempts to take a new look at the famous Lewis Carroll paradox about Achilles and the Tortoise. It examines in particular the connections between Lewis Carroll's regress argument for logical inferences and a similar regress for practical inferences. The Tortoise's point of view is espoused: no norm of reasoning or of conduct can in itself “make the mind move,” only the brute force of belief can. This conclusion is a Humean one. But it does not imply that we (...) renounce altogether the normative force of such principles of reasoning as modus ponens. Connexions with the Wittgensteinian rule-following problem are indicated.

In regard to the explanation of actions that are governed by institutional rules, John R. Searle introduces the notion of a mental “background” that is supposed to explain how persons can acquire the capacity of following such rules. I argue that Searle’s internalism about the mind and the resulting poverty of his conception of the background keep him from putting forward a convincing explanation of the normative features of institutional action. Drawing on competing conceptions of the background of Heidegger and (...) Wittgenstein, I propose to revise Searle’s conception. The background of institutional agency can only provide a convincing explanation if it includes the context of actions and intersubjective structures of a shared life-world. I suggest that a further development of this idea would lead to the identification of the background with a web of social recognition. (shrink)
