The taste of this particular chunk of fresh pineapple, the one which I am just now eating, is scrumptious. That taste is something the chunk has in common with other such chunks, like the one I had a few seconds ago and the one I will have in a few seconds time. The taste of this pineapple chunk is thus a feature, a property, which this and various other chunks of pineapple share. Now, intuitively at least, no purely mathematical entity, like a function, is scrumptious. Hence a property, like the taste of this chunk of pineapple, cannot be any such function. This kind of argument, if sound, would cut a wide swathe through the field of metaphysics. All those theories which attempt to reduce onto logically suspicious types of entities (properties, propositions, persons, medium- sized dry goods) to mathematical entities (like classes or functions) would fall to the blade. This could well help to reduce the impact of contemporary philosophy on the world's dwindling forests. I save contemporary metaphysics by explaining where the argument goes wrong.

An attractive admirer of George Bernard Shaw once wrote to him with a not-so modest proposal: ``You have the greatest brain in the world, and I have the most beautiful body; so we ought to produce the most perfect child.'' Shaw replied: ``What if the child inherits my body and your brains?''What if, indeed? Shaw's retort is interesting not because it revealsa grasp of elementary genetics, but rather because it suggests his grasp of an interesting and important principle of axiology. Since the brainy but ugly Shaw and his beautiful but apparently dim admirer both fall short of the ideal, she suggests that the best thing would be to genetically recombine his intelligence with her beauty. But what then would be the value of another genetic possibility: that of recombining his ugliness with her stupidity? Underlining the prompted inference is a fundamental principle of the theory of value which, perhaps surprisingly, has so far gone largely unnoticed in the ethical literature. I will call it the principle of recombinant values.

What is sovereignty? Was it ceded to the Crown in the Treaty of Waitangi? If land was unjustly confiscated over a century ago, should it be returned? Is an ecosystem valuable in itself, or only because of its value to people? Does a property right entail a right to destroy? Can collectives (such as tribes) bear moral responsibility? Do they have moral rights? If so, what are the implications for the justice system? These questions are essentially philosophical, yet all thoughtful New Zealanders will be keen to see them discussed clearly, rigorously, and dispassionately. This book gathers together essays by eminent philosophers on some of these problems. All of them are New Zealanders or have connections with this region. The problems which this book addresses on aspects of justice and ethics are of concern to all New Zealanders. Students of law, Maori studies, philosophy, politics, and history will find it particularly helpful.

I argue for an evaluative theory of desire—specifically, that to desire something is for it to appear, in some way or other, good. If a desire is a non-doxastic appearance of value then it is no mystery how it can rationalize as well as cause action. The theory is metaphysically neutral—it is compatible with value idealism (that value reduces to desire), with value realism (that it is not so reducible), and with value nihilism (all appearances of value are illusory). Despite this metaphysical neutrality the thesis opens up an epistemological gold mine. Non-doxastic value appearances can provide defeasible reasons for value judgements, in roughly the same way that perceptual appearances provide defeasible reasons for perceptual judgements. The paper presents a new line of argument for the evaluative theory—drawing on recent work on fitting attitudes—and rebuts some of the most pressing criticisms.

What's Wrong?: Applied Ethicists and Their Critics is a thorough and engaging introduction to applied ethics that covers virtually all of the issues in the field. Featuring more than ninety-five articles, it addresses standard topics--such as abortion, euthanasia, capital punishment, world hunger, and animal rights--and also delves into cutting-edge areas like cloning, racial profiling, same-sex marriage, prostitution, and slave reparations. The volume includes seminal essays by prominent philosophers (Robert Nozick, James Rachels, Peter Singer, and Judith Jarvis Thomson) alongside work by newer voices in the field. Employing a unique approach to teaching argumentation, editors David Boonin and Graham Oddie unify the wealth of material presented in this collection. Each chapter opens with a featured article that takes a strong stand on a particular issue; the essays that immediately follow offer objections and critical responses to the arguments put forth in the featured selection. This format helps students learn how to better engage in debates because it illustrates how philosophers argue with each other. In addition, a general introduction describes strategies for understanding and evaluating the different types of arguments contained in the readings, while detailed chapter introductions enable students to see precisely how the arguments presented in the various writings are related to one another. Discussion questions and suggestions for further reading are included for each chapter. Ideal for courses in introduction to ethics and applied ethics/contemporary moral problems, What's Wrong? can also be used in critical thinking courses that emphasize philosophical argumentation.

Why should a Bayesian bother performing an experiment, one the result of which might well upset his own favored credence function? The Ramsey-Good theorem provides a decision theoretic answer. Provided you base your decision on expected utility, and the the experiment is cost-free, performing the experiment and then choosing has at least as much expected utility as choosing without further ado. Furthermore, doing the experiment is strictly preferable just in case at least one possible outcome of the experiment could alter your choice of options. That is, you should pursue the information just in case it could make a difference to what you do. The problem remains, however, why one should do an experiment when nothing of much practical consequence hangs in the balance. One possibility here is to invoke the pure cognitive utility of states. It is shown that one constraint on cognitive value (what I call cogency) guarantees the value of learning: from a cognitive point of view you are justified in performing an experiment if the outcome of the experiment could make a different to what you think. A bonus of the basic framework is that it provides a new decision theoretic argument for the rationality of conditionalization.

The core of the truthmaker research program is that true propositions are made true by appropriate parts of the actual world. This idea seems to give realists their best shot at capturing a robust account of the dependence of truth on the world. For a part of the world to be a truthmaker for a particular it must suffice for, or necessitate, the truth of the proposition. There are two extreme and unsatisfactory truthmaker theories. At one extreme any part of the world (up to and including the whole world) that suffices for a proposition is deemed to be a truthmaker for that proposition. At the other extreme there is only one truthmaker that can do the job, and that is the entire world, the whole show. Another possibility suggests itself, that a truthmaker be any minimal sufficer for a proposition. A truthmaker is minimal if it suffices but no proper part of it suffices. A minimal sufficer would be both sufficient for the truth of the proposition and, in one sense, necessary for it as well. A minimal sufficers would be commensurate with the proposition it makes true. Unfortunately not all propositions have minimal sufficers. But it does not follow that not every proposition has a commensurate sufficer. The problem, then, is to specify a coherent notion of commensurateness on which every truth has a commensurate sufficer. I argue that this problem may not be soluble.

Theories of verisimilitude have routinely been classified into two rival camps—the content approach and the likeness approach—and these appear to be motivated by very different sets of data and principles. The question thus naturally arises as to whether these approaches can be fruitfully combined. Recently Zwart and Franssen (Synthese 158(1):75–92, 2007) have offered precise analyses of the content and likeness approaches, and shown that given these analyses any attempt to meld content and likeness orderings violates some basic desiderata. Unfortunately their characterizations of the approaches do not embrace the paradigm examples of those approaches. I offer somewhat different characterizations of these two approaches, as well as of the consequence approach (Schurz and Weingartner (Synthese 172(3):415–436, 2010) which happily embrace their respective paradigms. Finally I prove that the three approaches are indeed compatible, but only just, and that the cost of combining them is too high. Any account which combines the strictures of what I call the strong likeness approach with the demands of either the content or the consequence approach suffers from precisely the same defect as Popper’s—namely, it entails the trivialization of truthlikeness. The downside of eschewing the strong likeness constraints and embracing the content constraints alone is the underdetermination of the concept of truthlikeness

A number of different theories of truthlikeness have been proposed, but most can be classified into one of two different main programmes: the probability-content programme and the likeness programme.1 In Brink and Heidema [1987] we are offered a further proposal, with the attraction of some novelty. I argue that while the heuristic path taken by the authors is rather remote from what they call ‘the well-worn paths’,2 in fact their point of arrival is rather closer to existing proposals within the likeness approach than might at first appear. It is the purpose of this note to outline the logical connections and to assess the reasons which have been offered in favour of the new proposal.

Moral dilemmas can arise from uncertainty, including uncertainty of the real values involved. One interesting example of this is that of experimentation on human embryos and foetuses, If these have a moral stauts similar to that of human persons then there will be server constraitns on what may be done to them. If embryous have a moral status similar to that of other small clusters of cells, then constraints will be motivated largely by consideration for the persons into whom the embryos may develop. If the truth lies somewhere between these two extremes, the embryo having neither the full moral weight of persons, nor a completely negligible moral weight, then different kinds of constraints will be appropriate. On the face of it, in order to know what kinds of experiements, if any, we are morally justified in performing on embryos we have to know what the moral weight of the embryo is. But then an impasse threatens, for it seems implausible that we can settle with certainty the exact moral status of the human embryo. It is the purpose of this paper to show that moral uncertainty need not make rational moral justification impossible. I develop a framework which distinguishes between what is morally right/wrong, and what is morally justified/unjustified, and applies standard decision theoretic tools to the case of moral uncertainties. (This was the first published account of what has subsequently become known as Expected Moral Value Theory. An earlier version of the paper, "A decision theoretic argument against human embryo experimentation", was published in M. Fricke (ed.), Essays in honor of Bob Durrant. (University of Otago Press, 1986) 111-27.)
