Normative requirements are often overlooked, but they are central features of the normative world. Rationality is often thought to consist in acting for reasons, but following normative requirements is also a major part of rationality. In particular, correct reasoning – both theoretical and practical – is governed by normative requirements rather than by reasons. This article explains the nature of normative requirements, and gives examples of their importance. It also describes mistakes that philosophers have made as a result of confusing (...) normative requirements with reasons. (shrink)

A key to modern studies of 18th century Western philosophy, the Treatise considers numerous classic philosophical issues, including causation, existence, freedom and necessity and morality. This abridged edition has an introduction which explain's Hume's thought and places it in the context of its times.

One of Hume's most well-known works and a masterpiece of philosophy, A Treatise of Human Nature is indubitably worth taking the time to read.

Practical reasoning is a process of reasoning that concludes in an intention. One example is reasoning from intending an end to intending what you believe is a necessary means: 'I will leave the next buoy to port; in order to do that I must tack; so I'll tack', where the first and third sentences express intentions and the second sentence a belief. This sort of practical reasoning is supported by a valid logical derivation, and therefore seems uncontrovertible. A more contentious (...) example is normative practical reasoning of the form 'I ought to φ, so I'll φ', where 'I ought to φ' expresses a normative belief and 'I'll φ' an intention. This has at least some characteristics of reasoning, but there are also grounds for doubting that it is genuine reasoning. One objection is that it seems inappropriate to derive an intention to φ from a belief that you ought to φ, rather than a belief that you ought to intend to φ. Another is that you may not be able to go through this putative process of reasoning, and this inability might disqualify it from being reasoning. A third objection is that it violates the Humean doctrine that reason alone cannot motivate any action of the will. This paper investigates these objections. (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)

In this article I am concerned with whether it could be morally significant to distinguish between doing something 'in order to bring about an effect' as opposed to 'doing something because we will bring about an effect'. For example, the Doctrine of Double Effect tells us that we should not act in order to bring about evil, but even if this is true is it perhaps permissible to act only because an evil will thus occur? I discuss these questions in (...) connection with a version of the so-called Trolley Problem known as the Loop Case. I also consider how these questions may bear on whether a rational agent must aim at an event which he believes is causally necessary to achieve an end he pursues. (shrink)

Frances Kamm sets out to draw and make plausible distinctions that would show how and why it is, in some circumstances, permissible to kill some to save many more, but is not so in others. To do so she draws on a famous, and famously artificial, example of Judith Thomson, which illustrates the fact that people intutitively reject some instances of such killings but not others. The irrationality, implausibility and in many cases the self-defeating nature of such distinctions I had (...) attempted to expose in my 'The Survival Lottery' over 25 years ago. I still think these distinctions irrational and implausible and I will try, in this response, to show why this remains the case and why doctrines of additional effects, to however many powers they are taken, remain unhelpful in ethics.

Is morality rational? In this book Gauthier argues that moral principles are principles of rational choice. He proposes a principle whereby choice is made on an agreed basis of cooperation, rather than according to what would give an individual the greatest expectation of value. He shows that such a principle not only ensures mutual benefit and fairness, thus satisfying the standards of morality, but also that each person may actually expect greater utility by adhering to morality, even though the choice (...) did not have that end primarily in view. In resolving what may appear to be a paradox, the author establishes morals on the firm foundation of reason. Gauthier's argument includes an account of value, linking it to preference and utility; a discussion of the curcumstances in which morality is unnecessary; and an application of morals by agreement to relations between peoples at different levels of development and different generations. Finally, he reflects on the assumptions about individuality and community made by his account of rationality and morality. (shrink)

This book attempts to place a realist view of ethics (the claim that there are facts of the matter in ethics as elsewhere) within a broader context. It starts with a discussion of why we should mind about the difference between right and wrong, asks what account we should give of our ability to learn from our moral experience, and looks in some detail at the different sorts of ways in which moral reasons can combine to show us what we (...) should do in the circumstances. The second half of the book uses these results to mount an attack on consequentialism in ethics, arguing that there are more sorts of reasons around than consequentialists can even dream of.

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.

Dorsey rejects Conclusion, so he believes he must reject one of the premises. He argues that the best option is to reject Premise 3. Rejecting Premise 3 entails a certain sort of discontinuity in value. So Dorsey believes he has an argument for discontinuity.

Like all reasoning, practical reasoning is a process that takes a person from some of her existing mental states to a new mental state. Theoretical reasoning concludes in a belief; practical reasoning in an intention. This paper concentrates on instrumental reasoning, a species of practical reasoning in general. It argues that instrumental reasoning is correct if the content of the reasoning is a valid derivation, just as theoretical reasoning is correct if its content is a valid derivation. It also argues (...) that neither theoretical nor practical reasoning gives a reason for its conclusion. If a piece of reasoning is correct, it concludes in a state - a belief or an intention - that is rationally required by the states it is derived from, but rationally requiring a conclusion is not the same as giving a reason for it.
