Abstract

How persuasive are Rousseau’s and Diderot’s objections against Helvétius’s view that it is always interest that guides our esteem? Against Helvétius’s view that we always esteem ourselves in others, Rousseau objects that we can esteem the ideas that we recognize to be superior to our own ideas; against Helvétius’s idea that particu-lar societies and nations can only esteem ideas that are useful for them, Diderot objects that we can experience and esteem the feeling of universal benevolence. However, Rousseau and Diderot overlook that Helvétius’s conception of moral luck explains why experiences of the kind that they describe can occur. At the same time, Helvétius’s conception of moral luck explains why these experiences occur so rarely. This is why he holds that what we esteem needs to be modified through republican constitution building—expresses itself a kind of opti-mism concerning the possibility of cultivating morally good qualities of individuals through political agency.
