 Price’s answer to Hume is that, though we cannot create an obligation by our mere will and pleasure, we can place ourselves under an obligation by what we do or say, including when what we say expresses our will. On this central point, Price is correct. As we have seen, Price holds that the species of obligation under which I place myself in promising is veracity.  It may be that the moral category of honesty or trustworthiness would better capture what Price wants to say, but that is of comparatively secondary importance.
