Abstract

In this article, I offer a theoretical account of a central yet surprisingly overlooked form of legal influence or control, one that I refer to as the law’s ‘exhortative’ influence. The law exercises an ‘imperative’ influence when it purports to control agents’ behavior by imposing on them legal duties to act or refrain from acting in the legally desired or repelled way. By contrast, it exercises what I call an exhortative form of influence when it aims at impacting agents’ reasons for action whilst refraining from mandating or prohibiting the legally desired or repelled conduct. The law’s exhortative control or influence must be distinguished not only from its imperative influence, but also from what I call the law’s merely ‘instructive’ form of influence, such as the one provided by so-called power-conferring laws. Though I illustrate the functioning of this special form of legal control—the law’s exhortative influence—by using primarily the example of the law of contracts, the article offers novel insights about law in general as a mode of social ordering by developing a theory of the structure of ‘legal incentives’. Legal incentives, I contend, are the means through which the law exercises its exhortative influence. Clearly distinguishing different techniques of legal influence is not only of analytical interest, but should invite us to think of accounts of the justification of legal authority that consider the similarities but also the differences in the moral significance of these diverse techniques.
