A contractualist account of promising

T.M. Scanlon (1998) proposes that promise breaking is wrong because it shows manipulative disregard for the expectations for future behavior created by promising. I argue that this account of promissory obligation is mistaken in it own right, as well as being at odds with Scanlon's contractualism. I begin by placing Scanlon's account of promising within a tradition that treats the creation of expectations in promise recipients as central to promissory obligation. However, a counterexample to Scanlon's account, his case of the "Profligate Pal," will show that this view of promissory obligation, which I call the Expectations View, is incorrect. In its place, I propose an account of promissory obligation I call Promising as Accountability, according to which promising is a way of making oneself accountable to others for a future act. Not only is Promising as Accountability a more defensible approach to promissory obligation, it also better fits with certain general features of Scanlon's contractualism.
