When we have a normative reason, and we act for that reason, it becomes our motivating reason. But we can have either kind of reason without having the other. Thus, if I jump into the canal, my motivating reason was provided by my belief; but I had no normative reason to jump. I merely thought I did. And, if I failed to notice that the canal was frozen, I had a reason not to jump that, because it was unknown to (...) me, did not motivate me. Though we can have normative reasons without being motivated, and vice versa, such reasons are closely related to our motivation. There are, however, very different views about what this relation is. This disagreement raises wider questions about what normative reasons are, and about which reasons there are. After sketching some of these views, I shall discuss some arguments by Williams, and then say where, in my opinion, the truth lies. [...] I [will] suggest why, as I believe, we should be non-reductive normative realists, and should regard all reasons as external. (shrink)

Derek Parfit takes an externalist and cognitivist view about normative reasons. I shall explore this view and add some arguments that support it. But I shall also raise a doubt about it at the end.

have come in for increasing attention and controversy. A good example would be recent debates about moral realism where question of the relation between ethics (or ethical judgment) and the will has come to loom large.' Unfortunately, however, the range of positions labelled internalist in ethical writing is bewilderingly large, and only infrequently are important distinctions kept clear.2 Sometimes writers have in mind the view that sincere assent to a moral (or, more generally, an ethical) judgment concerning what one should (...) do is necessarily connected to motivation (actual or dispositional).s This necessity may be conceptual, or perhaps metaphysical, the thought being..
