Le "jeu de la constance" et le plus "apparent vice de nostre nature" :
constance et inconstance dans les Essais de Michel de Montaigne

This thesis aims to emphasize in Montaigne’s Essays a little known aspect concerning the debate of constancy towards the end of the 16th.  Century. While the virtue of constancy becomes a philosophical and moral issue of great importance, favouring at the same time the stoic, Christian and civil ideals, we observe in Montaigne’s Essays, an insistence to underline a contradictory phenomenon; inconstancy. First, it is essential to demonstrate the dialogue that builds Montaigne’s work concerning the virtue of constancy, to finally establish the proper argumentation on inconstancy in his Essays. In order to highlight this dialogue concealed in the patchwork of the Essays, we are proposing to combine internal and external reading, in order to evaluate thoroughly the act of writing they implicitly propose. With the intent to situate this debate concerning the virtue of constancy and the problem of inconstancy, we will refer primarily to the Hellenistic philosophies plundered by the Essays. We will present in the first part the origin and in the second part, the transfer of the debate. Montaigne’s scepticism happens to be destabilized, his stoicism is at the same time debated and rejected, his Epicureanism becoming a tool determining their truth. The inconstancy as mentioned takes a universal appearance making all references to the virtue of constancy as presumptuous, vain and even dangerous.  The second section of the thesis demonstrates that methodology of the Essays takes over the notion of inconstancy, notably through the “Distingo”, and its effects on the historical knowledge relating to prudential activities such as: jurisprudence, political and military life. Now that we have demonstrated that the work of Montaigne presents a radical critic of the method and the objectives of the moralists, we claim that the nature of the essay is to correct this error and thus give the right place to human inconstancy. We acknowledge the fact that inconstancy has a status of a pre-ethic condition which pushes the Essays to disrepute any human enterprise in the public sphere.  However, this denial cast upon the public sphere does not lead us to reject any kind of ethical reflection. Therefore, the Essays do not exclusively encourage letting faith or fortune carry us. In the private sphere, the third book of the Essays constructs many ethical regulations that are astonishing and heterodox: non repentance, diversion, vanity, experience...These aspects are all grounded in the ethical mode of the possible, (« Selon qu’on peut ») and at the same time contribute in redefining the magnitude of the soul (magntiudo animi, mégalopsychè) by presenting a new order or a new conformity of action. Beyond the moral analysis and the description of oneself, an ethical process seizes the imperfect movement of existence in the Essays, which erects itself not against inconstancy but in harmony with it. This ethic of inconstancy or ethic of indirection is built in opposition with the moral doctrines even though a constant debate seems to unite them.
