At the heart of John Broome’s research program in the philosophy of normativity is a distinction between reasons, on one hand, and requirements of rationality, on the other. I am a friend of Broome’s view that this distinction is deep and important, and that neither notion can be analyzed in terms of the other. However, I also think there are major challenges that this view is yet to meet. In the first part of the paper, I’ll raise four such challenges, (...) and programmatically indicate how I think such challenges might be headed off. In the second part of the paper, I’ll discuss a third normative notion that Broome is interested in: that of (rules of) correct reasoning. On Broome’s view, correct reasoning is closely tied to requirements of rationality. More particularly, every rule of correct reasoning corresponds to a “basing permission”, which states that it’s rationally permissible to base one attitude on one or more other attitudes. I’ll argue that this proposal can’t be made to work. If I’m right, this suggests that the same kind of pulling-apart that Broome has effected so persuasively with respect to reasons and requirements of rationality needs to be effected again to separate rules of correct reasoning from both of those other categories.

If a potential person would have a good life if he were to come into existence, can we coherently regard his coming into existence as better for him than his never coming into existence? And can we regard the situation in which he never comes into existence as worse for him? In this paper, we argue that both questions should be answered affirmatively. We also explain where prominent arguments to differing conclusions go wrong. Finally, we explore the relevance of our (...) answers to issues in population ethics. (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.

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)

Since the last ice age, when ice enveloped most of the northern continents, the earth has warmed by about five degrees. Within a century, it is likely to warm by another four or five. This revolution in our climate will have immense and mostly harmful effects on the lives of people not yet born. We are inflicting this harm on our descendants by dumping greenhouse gases into the atmosphere. We can mitigate the harm a little by taking measures to control (...) our emissions of these gases, and to adapt to the changes by, for instance, building sea walls around coastlines threatened by rising sea levels. But these measures will be very expensive, and the costs will be born by us, the present generation, whereas the benefits will come to future generations. How much should we sacrifice for the sake of the future? Economists and philosophers have independently worked on the question of our responsibility to future generations. This book brings their work together and applies it to global warming. It suggests a programme for future research on the economic and ethical issues. The book is intended for economists, and for philosophers and other social scientists who have a little knowledge of economic methods. (shrink)

Philosophy of Science is a mid-level text for students with some grounding in philosophy. It introduces the questions that drive enquiry in the philosophy of science, and aims to educate readers in the main positions, problems and arguments in the field today. Alex Rosenberg is certainly well qualified to write such an introduction. His works cover a large area of the philosophy of natural and social sciences. In addition, the author of the argument that the ‘queen of the social (...) sciences’, economics, is not a science at all, can be counted on to show how the philosophy of science can be relevant to the understanding of the status of scientific knowledge and can provide a critical assessment of practitioners’ view of their field.

John Broome argues that when all claims cannot be perfectly fairly satisfied in outcome, the contribution to fairness from entering claims into a lottery, and so providing them some surrogate satisfaction, ought to be weighed against, and can outweigh, what fairness can be achieved directly in outcome. I argue that this is a mistake. Instead, I suggest that any contribution to fairness from entering claims into a lottery is lexically posterior to fairness in outcome.

John Broome’s Rationality Through Reasoning is a trail-blazing study of the nature of rationality, the nature of reasoning and the connection between the two. But it may be somewhat misleading in two respects. First, his theory of reasoning is consistent with the meta-propositional view that he rejects; it develops a broadly similar theory but in much greater detail. And while his discussion of rule-following helps to explain the role of rules in reasoning, it does not constitute a response to the (...) classic problem associated with Wittgenstein and Kripke.

In “Weighing Lives” (2004) John Broome criticizes a view common to many population axiologists. On that view, population increases with extra people leading decent lives are axiologically neutral: they make the world neither better nor worse, ceteris paribus. Broome argues that this intuition, however, attractive, cannot be sustained, for several independent reasons. I respond to his criticisms and suggest that the neutrality intuition, if correctly interpreted, can after all be defended.On the version I defend,the world with added extra people at (...) wellbeing levels within the neutrality range is incommensurable in value with the world in which these peaople are absent.

and Overview In an earlier book, Weighing Goods1, John Broome gave a sophisticated defense of utilitarianism for the cases involving a fixed population. In the present book, Weighing Lives, he extends this defense to variable population cases, where different individuals exist depending on which choice is made. Broome defends a version of utilitarianism according to which there is a vague positive level of individual wellbeing such that adding a life with more than that level of wellbeing makes things morally better (...) and adding a life with less than that level makes things morally worse. This version of utilitarianism avoids the extreme—but perhaps not all— forms of the repugnant conclusion that the usual total version faces. As usual, Broome’s work combines logical rigor with deep philosophical insight. There is much to learn from it. Nonetheless, I shall identify some problematic conditions used by Broome to derive utilitarianism and suggest that Broome’s version of utilitarianism has implausible implications. (shrink)

John Broome defends what he calls ‘Enkrasia’, which is roughly this: Rationality requires of you that if you believe that you ought to do A, you intend to do A. He provides two arguments for Enkrasia. First, he argues for what he calls ‘enkratic reasoning’: ‘I ought to do A. So I shall do A’. Second, he also provides the following line of argument: Enkrasia is the requirement not to be akratic; akrasia is irrational; so Enkrasia is a rational requirement. (...) The purpose of this paper is to show that these two arguments are not successful. For this purpose, I argue for two things. The alleged enkratic reasoning is not a genuine rule of reasoning. And it is not appropriate to understand Enkrasia in terms of akrasia, either. (shrink)

ABSTRACT As a part of John Broome’s stated aim to establish a clear distinction between rationality and normativity, Broome suggests a novel definition of normativity as a property term that applies to persons. Since this construal of normativity diverges significantly from most prominent renderings of the concept within contemporary philosophical discussions, it merits critical scrutiny. In response to Broome, I thus examine the technical advantage of Broome’s approach, while also indicating some drawbacks of Broome’s novel conceptualization of ‘normative’ and ‘normativity’.

Neuroscience has long had an impact on the field of psychiatry, and over the last two decades, with the advent of cognitive neuroscience and functional neuroimaging, that influence has been most pronounced. However, many question whether psychopathology can be understood by relying on neuroscience alone, and highlight some of the perceived limits to the way in which neuroscience informs psychiatry. -/- Psychiatry as Cognitive Neuroscience is a philosophical analysis of the role of neuroscience in the study of psychopathology. The book (...) examines numerous cognitive neuroscientific methods, such as neuroimaging and the use of neuropsychological models, in the context of a variety of psychiatric disorders, including depression, schizophrenia, dependence syndrome, and personality disorders. -/- Psychiatry as Cognitive Neuroscience includes chapters on the nature of psychiatry as a science; the compatibility of the accounts of mental illness derived from neuroscience, information-processing, and folk psychology; the nature of mental illness; the impact of methods such as fMRI, neuropsychology, and neurochemistry, on psychiatry; the relationship between phenomenological accounts of mental illness and those provided by naturalistic explanations; the status of delusions and the continuity between delusions and ordinary beliefs; the interplay between clinical and empirical findings in psychopathology and issues in moral psychology and ethics. -/- With contributions from world class experts in philosophy and cognitive science, this book will be essential reading for those who have an interest in the importance and the limitations of cognitive neuroscience as an aid to understanding mental illness.

I argue that the accounts of inference recently presented (in this journal) by Paul Boghossian, John Broome, and Crispin Wright are unsatisfactory. I proceed in two steps: First, in Sects. 1 and 2, I argue that we should not accept what Boghossian calls the “Taking Condition on inference” as a condition of adequacy for accounts of inference. I present a different condition of adequacy and argue that it is superior to the one offered by Boghossian. More precisely, I point out (...) that there is an analog of Moore’s Paradox for inference; and I suggest that explaining this phenomenon is a condition of adequacy for accounts of inference. Boghossian’s Taking Condition derives its plausibility from the fact that it apparently explains the analog of Moore’s Paradox. Second, in Sect. 3, I show that neither Boghossian’s, nor Broome’s, nor Wright’s account of inference meets my condition of adequacy. I distinguish two kinds of mistake one is likely to make if one does not focus on my condition of adequacy; and I argue that all three—Boghossian, Broome, and Wright—make at least one of these mistakes.

“Utility,” in plain English, means usefulness. In Australia, a ute is a useful vehicle. Jeremy Bentham specialized the meaning to a particular sort of usefulness. “By utility,” he said, “is meant that property in any object, whereby it tends to produce benefit, advantage, pleasure, good, or happiness or to prevent the happening of mischief, pain, evil, or unhappiness to the party whose interest is considered”. The “principle of utility” is the principle that actions are to be judged by their usefulness (...) in this sense: their tendency to produce benefit, advantage, pleasure, good, or happiness. When John Stuart Mill spoke of the “perfectly just conception of Utility or Happiness, considered as the directive rule of human conduct,” he was using “Utility” as a short name for this principle. “The greatest happiness principle” was another name for it. People who subscribed to this principle came to be known as utilitarians. (shrink)

Among the many important contributions of John Broome’s Rationality Through Reasoning is an account of what reasoning is and what makes reasoning correct. In this paper we raise some problems for both of these accounts and recommend an alternative approach.

ABSTRACT Normativity seems characteristically, perhaps essentially, explained by claims about the competition between normative reasons. John Broome’s ‘quick objection’ aims to show that rationality cannot be explained by claims about normative reasons and, thus, that it is not normative. Broome’s objection turns on the idea that rationality is mind-dependent in a way that facts about reasons are not. However, this objection is shaped by a popular, powerful, and restrictive assumption about the substance of normative reasons called factualism, which holds that (...) the substances that are reasons are facts, either in the sense of true propositions or of the truth-makers of such propositions. I suggest that support for factualism is weaker than its popularity suggests. In particular, I suggest that arguments for factualism from the nature of normative explanation, expressions attributing reasons, the relationship between normativity and actuality, and common sense are weaker than they appear. Rejecting factualism allows us to tie some class of reasons—subjective reasons, we might call them—more closely to the mind and to thereby ground the normativity of rationality. Thus, Broome’s ‘quick objection’ is too quick for it must account for the possibility of non-factualist reasons. (shrink)

A short encyclopaedia entry on John Broome.

Alex Oliver and Timothy Smiley provide a new account of plural logic. They argue that there is such a thing as genuinely plural denotation in logic, and expound a framework of ideas that includes the distinction between distributive and collective predicates, the theory of plural descriptions, multivalued functions, and lists.

In The Moral Dimension, Amitai Etzioni claims, as did Albert Hirschman in Morality and the Social Sciences, that people often act from moral motives, that economics needs to recognize this, and that it will be significantly changed by doing so. I agree, though I think the changes may be smaller than Etzioni believes – I shall be explaining why. But Etzioni goes further. He makes a specific claim about the sort of morality that motivates people: it is deontological. In this (...) paper, I shall examine what this means, how far it is true, and what difference it makes. (shrink)

Esteemed philosopher John Broome avoids the familiar ideological stances on climate change policy and examines the issue through an invigorating new lens. As he considers the moral dimensions of climate change, he reasons clearly through what universal standards of goodness and justice require of us, both as citizens and as governments. His conclusions—some as demanding as they are logical—will challenge and enlighten. Eco-conscious readers may be surprised to hear they have a duty to offset all their carbon emissions, while policy (...) makers will grapple with Broome’s analysis of what if anything is owed to future generations. From the science of greenhouse gases to the intricate logic of cap and trade, Broome reveals how the principles that underlie everyday decision making also provide simple and effective ideas for confronting climate change. Climate Matters is an essential contribution to one of the paramount issues of our time. (shrink)

Should social preferences conform to the principles of rationality we normally expect of individuals? Should they, for instance, conform to the consistency axioms of expected utility theory? This article considers one fragment of this question.

Priority monism is the view that the cosmos is the only independent concrete object. The paper argues that, pace its proponents, Priority monism is in conflict with the dependence of any whole on any of its parts: if the cosmos does not depend on its parts, neither does any smaller composite.

We are often faced with choices that involve the weighing of people's lives against each other, or the weighing of lives against other good things. These are choices both for individuals and for societies. A person who is terminally ill may have to choose between palliative care and more aggressive treatment, which will give her a longer life but at some cost in suffering. We have to choose between the convenience to ourselves of road and air travel, and the lives (...) of the future people who will be killed by the global warming we cause, through violent weather, tropical disease, and heat waves. We also make choices that affect how many lives there will be in the future: as individuals we choose how many children to have, and societies choose tax policies that influence people's choices about having children. These are all problems of weighing lives. How should we weigh lives? Weighing Lives develops a theoretical basis for answering this practical question. It extends the work and methods of Broome's earlier book Weighing Goods to cover the questions of life and death. Difficult problems come up in the process. In particular, Weighing Lives tackles the well-recognized, awkward problems of the ethics of population. It carefully examines the common intuition that adding people to the population is ethically neutral - neither a good nor a bad thing - but eventually concludes this intuition cannot be fitted into a coherent theory of value. In the course of its argument, Weighing Lives examines many of the issues of contemporary moral theory: the nature of consequentialism and teleology; the transitivity, continuity, and vagueness of betterness; the quantitative conception of wellbeing; the notion of a life worth living; the badness of death; and others. This is a work of philosophy, but one of its distinctive features is that it adopts some of the precise methods of economic theory (without introducing complex mathematics). Not only philosophers, but also economists and political theorists concerned with the practical question of valuing life, should find the book's conclusions highly significant to their work.
