In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

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.

In this paper1 I shall present not just the conscience of Huckleberry Finn but two others as well. One of them is the conscience of Heinrich Himmler. He became a Nazi in 1923; he served drably and quietly, but well, and was rewarded with increasing responsibility and power. At the peak of his career he held many offices and commands, of which the most powerful was that of leader of the S.S. - the principal police force of the Nazi regime. (...) In this capacity, Himmler commanded the whole concentration-camp system, and was responsible for the execution of the so-called ‘final solution of the Jewish problem’. It is important for my purposes that this piece of social engineering should be thought of not abstractly but in concrete terms of Jewish families being marched to what they think are bath-houses, to the accompaniment of loud-speaker renditions of extracts from The Merry Widow and Tales of Hoffman, there to be choked to death by poisonous gases. Altogether, Himmler succeeded in murdering about four and a half million of them, as well as several million gentiles, mainly Poles and Russians. The other conscience to be discussed is that of the Calvinist theologian and philosopher Jonathan Edwards. He lived in the first half of the eighteenth century, and has a good claim to be considered America’s first serious and considerable philosophical thinker. He was for many years a widely-renowned preacher and Congregationalist minister in New England; in 1748 a dispute with his congregation led him to resign (he couldn’t accept their view that unbelievers should be admitted to the Lord’s Supper in the hope that it would convert them); for some years after that he worked as a missionary, preaching to Indians through an interpreter;, then in 1758 he accepted the presidency of what is now Princeton University, and within two months died from a smallpox inoculation. Along the way he wrote some first-rate philosophy: his book attacking the notion of free will is still sometimes read.. (shrink)

I argue that akrasia is not always significantly irrational. To be more precise, I argue that an agent is sometimes more rational for being akratic then she would have been for being enkratic or strong-willed.

Some contemporary theories treat phenomena like weakness of will, compulsion and wantonness as practical failures but not as failures of rationality: say, as failures of autonomy or whatever. Other current theories-the majority see the phenomena as failures of rationality but not as distinctively practical failures. They depict them as always involving a theoretical deficiency: a sort of ignorance, error, inattention or illogic. They represent them as failures which are on a par with breakdowns of theoretical reason; the failures may not (...) have exact theoretical analogues, exact analogues in the breakdown of belief, but they are of essentially the same, cognitive kind. Our approach gives us quite a different view of things. The pathologies which we identify in our taxonomy are distinctively rational failures and distinctively practical failures; they are failures of pure practical reason. (shrink)

Granted that desire is always present in the genesis of human action, is it something on the presence of which the agent always reflects? I may act on a belief without coming to recognize that I have the belief. Can I act on a desire without recognizing that I have the desire? In particular, can the desire have a motivational presence in my decision making, figuring in the background, as it were, without appearing in the content of my deliberation, in (...) the foreground? We argue, perhaps unsurprisingly, that yes, desire can figure in the background without figuring in the foreground: we call this the strict background view of desire. But we then show, and this is where the surprise comes, that the strict background view of desire has significant implications for contemporary moral philosophy. (shrink)

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)

I am going to argue that linking Hume’s name with instrumentalism is as inappropriate as linking Aristotle’s: that, as a matter of textual point, the Hume of the Treatise is not an instrumentalist at all, and that the view of practical reasoning that he does have is incompatible with, and far more minimal than, instrumentalism. Then I will consider Hume’s reasons for his view, and argue that they make sense when they are seen against the background of his semantic theory. (...) And finally, I will try to say why it is that Hume has nonetheless been read as he has. (shrink)

Content skepticism about practical reason is doubt about the bearing of rational considerations on the activities of deliberation and choice. Motivational skepticism is doubt about the scope of reason as a motive. Some people think that motivational considerations alone provide grounds for skepticism about the project of founding ethics on practical reason. I will argue, against this view, that motivational skepticism must always be based on content skepticism. I will not address the question of whether or not content skepticism is (...) justified. I want only to establish the fact that motivational skepticism has no independent force. (shrink)
