Si les savants du xviie siècle revendiquaient la responsabilité morale qui découlait de leur connaissance particulière, leurs mécènes préféraient les applications fidèles et utiles de cette connaissance. Un savant osait-il, donc, s’opposer à son mécène? Trois associés, au moins, de l’Académie royale des sciences se distinguatient de Louis XIV sur des questions de philosophie naturelle, de religion et de politique. Le cas de l’un d’eux, Nicolas Hartsoeker, un savant hollandais et fabricant d’instruments d’optique, espion de Louis XIV pendant la guerre (...) de la Ligue d’Augsbourg, révèle des liens complexes entre science et conscience pendant la révolution scientifique.

In The Structural Transformation of the Public Sphere, Habermas makes the claim that the unprecedented public use of critical reason was an essential constituent of the early modern European (bourgeois) public sphere (1991, 27-28, 105-6, and more generally 1-117). Narrating the history of the particular concept of critical reason that animated the public sphere, Habermas locates its origin in the practical reason (phronesis) of Aristotle but argues that Niccolò Machiavelli and Thomas More had drastically transformed the concept when they substituted (...) for phronesis a practical reason based instead on techne (1973, 42, 50-51). Machiavelli's role was central in this transformation, for he "reduces the practical .. (shrink)

While Montesquieu (1689–1755) is often regarded as the thinker who discovered the importance of fundamental principles such as the rule of law and the separation of powers, systematic research of his theory of the state is surprisingly limited. In this article, I argue that his masterpiece, The Spirit of the Laws (1748), points to a theory of the non-arbitrary state. Montesquieu’s comparative study of various governments demonstrates that modern liberty depends on the rule of law. Since many states have laws (...) but few of them guarantee liberty, he stressed that the rule of law requires the separation of the judicial from the legislative and executive powers. The constitution of an independent judicial branch separates the sphere of justice from the political sphere, which creates the basic structure of the non-arbitrary state. Depending on the distribution of power in either of the two spheres, non-arbitrary states can guarantee their citizens more or less liberty. The concept of the non-arbitrary state thus illuminates Montesquieu’s significance for the variety of political projects that emerged in the age of revolutions. (shrink)

La dimension politique du scepticisme, considère-t-on souvent, c'est le conformisme. Mais la séparation entre le domaine intérieur et l'espace public n'a pas pour seule conséquence l'injonction de suivre la coutume. Elle est d'abord constitution du domaine privé, qui est un lieu de liberté, à l'écart de la foule et du pouvoir. Cela permet de mieux comprendre la position sceptique en politique: le conseil du prince, en secret et en retrait de l'éclat public. Cela permet surtout de comprendre ce qu'apporte le (...) scepticisme aux conceptions modernes de la liberté: un modèle social de la libre poursuite de la vérité. (shrink)
