Whereas many others have scrutinized the Allais paradox from a theoretical angle, we study the paradox from an historical perspective and link our findings to a suggestion as to how decision theory could make use of it today. We emphasize that Allais proposed the paradox as a normative argument, concerned with ‘the rational man’ and not the ‘real man’, to use his words. Moreover, and more subtly, we argue that Allais had an unusual sense (...) of the normative, being concerned not so much with the rationality of choices as with the rationality of the agent as a person. These two claims are buttressed by a detailed investigation – the first of its kind – of the 1952 Paris conference on risk, which set the context for the invention of the paradox, and a detailed reconstruction – also the first of its kind – of Allais’s specific normative argument from his numerous but allusive writings. The paper contrasts these interpretations of what the paradox historically represented, with how it generally came to function within decision theory from the late 1970s onwards: that is, as an empirical refutation of the expected utility hypothesis, and more specifically of the condition of von Neumann–Morgenstern independence that underlies that hypothesis. While not denying that this use of the paradox was fruitful in many ways, we propose another use that turns out also to be compatible with an experimental perspective. Following Allais’s hints on ‘the experimental definition of rationality’, this new use consists in letting the experiment itself speak of the rationality or otherwise of the subjects. In the 1970s, a short sequence of papers inspired by Allais implemented original ways of eliciting the reasons guiding the subjects’ choices, and claimed to be able to draw relevant normative consequences from this information. We end by reviewing this forgotten experimental avenue not simply historically, but with a view to recommending it for possible use by decision theorists today. (shrink)

This article documents the history of the Allais paradox, and shows that underneath the many discussions of the various protagonists lay different, irreconcilable epistemological positions. Savage, like his mentor von Neumann and similar to economist Friedman, worked from an epistemology of generalized characterizations. Allais, on the other hand, like economists Samuelson and Baumol, started from an epistemology of exact descriptions in which every axiom was an empirical claim that could be refuted directly by observations. As a result, (...) the two sides failed to find a common ground. Only a few decades later was the now so-called Allais paradox rediscovered as an important precursor when a new behavioural economic subdiscipline started to adopt the epistemology of exact descriptions and its accompanying falsifications of rational choice theory.

This paper uses a two-dimensional version of a standard common consequence experiment to test the intransitivity explanation of Allais-paradox-type violations of expected utility theory. We compare the common consequence effect of two choice problems differing only with respect to whether alternatives are statistically correlated or independent. We framed the experiment so that intransitive preferences could explain violating behavior when alternatives are independent, but not when they are correlated. We found the same pattern of violation in the two cases. (...) This is evidence against intransitivity as an explanation of the Allais Paradox. The question whether violations of expected utility are mainly due to intransitivity or to violation of independence is important since it is exactly on this issue the main new decision theories differ.

This paper investigates the relation between consequentialism, as conceived of in moral theory, and standard expected utility theory. I argue that there is a close connection between the two. I show furthermore that consequentialism is not neutral with regard to the values of the agent. Consequentialism, as well as standard expected utility theory, is incompatible with the recognition of considerations that depend on what could have been the case, such as regret and disappointment. I conclude that consequentialism should be rejected (...) as a principle of rational choice and that there are reasons to doubt its plausibility in the realm of moral theory. Moreover, this is a reason to doubt whether standard expected utility theory is a plausible theory of rational choice. (shrink)

In The Enterprise of Knowledge, I proposed a general theory of rational choice which I intended as a characterization of a prescriptive theory of ideal rationality. A cardinal tenet of this theory is that assessments of expected value or expected utility in the Bayesian sense may not be representable by a numerical indicator or indeed induce an ordering of feasible options in a context of deliberation. My reasons for taking this position are related to my commitment to the inquiry-oriented approach (...) to human knowledge and valuation favored by the American pragmatists, Charles Peirce and John Dewey. A feature of any acceptable view of inquiry ought to be that during an inquiry points under dispute ought to be kept in suspense pending resolution through inquiry. (shrink)

In Risk and Rationality, Lara Buchak advertised REU theory as able to recover the modal preferences in the Allais paradox. But we pointed out that REU theory only applies in the “grand world” setting, where it actually struggles with the modal Allais preferences. Buchak offers two replies. Here we enumerate technical and philosophical problems they face.

In Richard Bradley’s book, Decision Theory with a Human Face, we have selected two themes for discussion. The first is the Bolker-Jeffrey theory of decision, which the book uses throughout as a tool to reorganize the whole field of decision theory, and in particular to evaluate the extent to which expected utility theories may be normatively too demanding. The second theme is the redefinition strategy that can be used to defend EU theories against the Allais and Ellsberg paradoxes, a (...) strategy that the book by and large endorses, and even develops in an original way concerning the Ellsberg paradox. We argue that the BJ theory is too specific to fulfil Bradley’s foundational project and that the redefinition strategy fails in both the Allais and Ellsberg cases. Although we share Bradley’s conclusion that EU theories do not state universal rationality requirements, we reach it not by a comparison with BJ theory, but by a comparison with the non-EU theories that the paradoxes have heuristically suggested.

Sorensen provides a panoramic view of paradoxes of theoretical and practical rationality. These puzzles are organized as apparent counterexamples to attractive principles such as the principle of charity, the transitivity of preferences, and the principle that we should maximize expected utility. The following paradoxes are discussed: fearing fictions, the surprise test paradox, Pascal’s Wager, Pollock’s Ever Better wine, Newcomb’s problem, the iterated prisoner’s dilemma, Kavka’s paradoxes of deterrence, backward inductions, the bottle imp, the preface paradox, Moore’s problem, Buridan’s (...) ass, Condorcet’s paradox of cyclical majorities, the St. Petersburg paradox, weakness of will, the Ellsberg paradox, Allais’s paradox, and Peter Cave’s puzzle of self-fulfilling beliefs.

After a long period of comparative neglect, in the last few decades growing numbers of philosophers have been paying attention to the startling contrast presented between Kant’s universal moral theory, with its inspiring enlightenment ideas of human autonomy, equality and dignity and Kant’s racism. Against Charles Mills, who argues that the way to make Kant consistent is by attributing to him a threshold notion of moral personhood, according to which some races do not qualify for consideration under the categorical imperative, (...) I argue that Kant cannot be made consistent on race, and that rather than trying to make him so, we should use the example of Kant’s racism to tell us something about the nature of racism. I argue that Kant’s own moral philosophy and moral psychology in fact give some materials for thinking about his racism, and about racism. (shrink)

In this paper I present a critique of some aspects of Thad Metz’s attempt to develop an African moral theory grounded on the value of ubuntu. I question the sense in which this theory is African, as well as his attempt to ground human rights on his single value theory of ubuntu. In a number of publications Thad Metz has given a clear, analytic account of what ubuntu is. Metz’s work on ubuntu does two things: 1) explains the content of (...) ubuntu: what the value/virtue is; 2) presents a moral theory according to which appealing to ubuntu as a basic value enables us to explain what makes all actions right or wrong. He calls this an African moral theory. It is the second part I am skeptical about. He makes it plausible that ubuntu is an important value. And he shows how we can give it some clear content. However, I argue that he does not make plausible a single-value ethical theory based on ubuntu; it is not plausible as an ethical theory, and it is not plausible that such a theory is African in any significant sense.

Lucy Allais presents an original interpretation of Kant's transcendental idealism. She argues that his distinction between things in themselves and things as they appear to us has both epistemological and metaphysical components. Kant is committed to a genuine idealism about things as they appear to us, but this is not a phenomenalist idealism. He is committed to the claim that there is an aspect of reality that grounds mind-dependent spatio-temporal objects, and which we cannot cognize, but he does not (...) assert the existence of distinct non-spatio-temporal objects. On Allais's account, we cannot understand Kant's idealism without a clear account of his notion of intuition and of the role of intuition in cognition: she understands Kantian intuitions as representations that give us acquaintance with the objects of thought. This enables us to make sense of Kant's central argument for his idealism in the Transcendental Aesthetic, and to see why he takes the complete idealist position to be established there. (shrink)

:Space is not an empirical concept that has been drawn from outer experiences. For in order for certain sensations to be related to something outside me , thus in order for me to represent them as outside and next to one another, thus not merely different but as in different places, the representation of space must already be their ground. Thus the representation of space cannot be obtained from the relations of outer appearance through experience, but this outer experience is (...) itself first possible only through this representation. 1Abstract:Der Raum is kein empirischer Begriff, der von äußeren Erfahrungen abgezogen worden. Denn damit gewisse Empfindungen auf etwas außer mir bezogen werden, imgleichen damit ich sie als außer und neben einander, mithin nicht bloß verschieden, sondern als in verschiedenen Orten vorstellen können, dazu muß die Vorstellung des Raumes schon zum Grunde liegen.

Kant has a number of harsh-sounding things to say about beggars and giving to beggars. He describes begging as “closely akin to robbery”, and says that it exhibits self-contempt. In this paper I argue that on a particular interpretation of his political philosophy his critique of giving to beggars can be seen as part of a concern with social justice, and that his analysis makes sense of some troubling aspects of the phenomenology of being confronted with beggars. On Kant's view, (...) without absolute poverty relief, the poor persons' external freedom is subject to the arbitrary choices of those who have means. But the legitimacy of the state is based on ensuring that no one's basic freedom is subject to the arbitrary choices of another. This means that in a legitimate state public structures must ensure that there is unconditional poverty relief. Having your basic needs met through private charity wrongs you. Kant's analysis is that when you encounter someone in a public space who asks you for money to meet their basic survival needs, you are being asked to solve a public problem in a private interaction, and there is no rightful way for you to do this.

This paper examines the idea that forgiveness requires, either for its existence or for its justification, the meeting of moral and epistemic conditions which show that resentment is no longer warranted. I argue that this idea results in over-intellectualizing and over-moralizing forgiveness, and in failing to accommodate its elective nature. I sketch an alternative account, which appeals to the differences between emotions and beliefs, and the idea that we have more rational optionality with respect to emotions.

: Interpretations of Kant's transcendental idealism have been dominated by two extreme views: phenomenalist and merely epistemic readings. There are serious objections to both of these extremes, and the aim of this paper is to develop a middle ground between the two. In the Prolegomena, Kant suggests that his idealism about appearances can be understood in terms of an analogy with secondary qualities like color. Commentators have rejected this option because they have assumed that the analogy should be read in (...) terms of either a Lockean or a Berkelean account of qualities such as color, and have argued, rightly, that neither can provide the basis for a coherent interpretation of Kant's position. I argue that the account of color that the analogy requires is one within the context of a direct theory of perception, as opposed to Locke's representative account. Using this account of color, the secondary quality analogy enables us to explain how appearances can be mind-dependent without existing in the mind. (shrink)

This paper argues that one part of the picture of thinking about decolonising the philosophy curriculum should include problematising the notion of Western philosophy. I argue that there are many problems with the idea of Western philosophy, and with the idea that decolonising the curriculum should involve rejecting so-called Western philosophy. Doing this could include granting the West a false narrative about its origins, influences and interactions, perpetuating exclusions within contemporary and recent North American and European philosophy, perpetuating exclusions and (...) failed acknowledgements within the history of so-called Western philosophy, while at the same time rejecting a tradition which has included in itself so many topics and methodologies that what is left after excluding it would leave other traditions with limited resources, at the same time as wrongly granting the West proprietary rights over any ideas it has happened to investigate, rather than seeing these as belonging to all of humanity. I therefore conclude that a central part of curriculum change should be problematising Western philosophy, including our learning more about, and teaching, more complex views of its history and interactions with other traditions.

This paper gives an interpretation of Kant's argument for transcendental idealism in the Transcendental Aesthetic. I argue against a common way of reading this argument, which sees Kant as arguing that substantive a priori claims about mind-independent reality would be unintelligible because we cannot explain the source of their justification. I argue that Kant's concern with how synthetic a priori propositions are possible is not a concern with the source of their justification, but with how they can have objects. I (...) argue that Kant's notion of intuition needs to be understood as a kind of representation which involves the presence to consciousness of the object it represents, and that this means that a priori intuition cannot present us with a mind-independent feature of reality.

This paper argues that there is an important respect in which Rae Langton's recent interpretation of Kant is correct: Kant's claim that we cannot know things in themselves should be understood as the claim that we cannot know the intrinsic nature of things. However, I dispute Langton's account of intrinsic properties, and therefore her version of what this claim amounts to. Langton's distinction between intrinsic, causally inert properties and causal powers is problematic, both as an interpretation of Kant, and as (...) an independent metaphysical position. I propose a different reading of the claim that we cannot know things intrinsically. I distinguish between two ways of knowing things: in terms of their effects on other things, and as they are apart from these. I argue that knowing things' powers is knowing things in terms of effects on other things, and therefore is not knowing them as they are in themselves, and that there are textual grounds for attributing this position to Kant.

This paper compares Kant's transcendental idealism with three main groups of contemporary anti-realism, associated with Wittgenstein, Putnam, and Dummett, respectively. The kind of anti-realism associated with Wittgenstein has it that there is no deep sense in which our concepts are answerable to reality. Associated with Putnam is the rejection of four main ideas: theory-independent reality, the idea of a uniquely true theory, a correspondence theory of truth, and bivalence. While there are superficial similarities between both views and Kant's, I find (...) more significant differences. Dummettian anti-realism, too, clearly differs from Kant's position: Kant believes in verification-transcendent reality, and transcendental idealism is not a theory of meaning or truth. However, I argue that part of the Dummettian position is extremely useful for understanding part of Kant's position - his idealism about the appearances of things. I argue that Kant's idealism about appearances can be expressed as the rejection of experience-transcendent reality with respect to appearances. (shrink)

The last few years have seen dramatic progress in the development of HIV pre-exposure prophylaxis (PrEP). These developments have been met by ethical concerns. HIV interventions are often thought to be ethically difficult. In a context which includes disagreements over human rights, controversies over testing policies, and questions about sexual morality and individual responsibility, PrEP has been seen as an ethically complex intervention. We argue that this is mistaken, and that in fact, PrEP does not raise new ethical concerns. Some (...) of the questions posed by PrEP are not specific to HIV prophylaxis, but simply standard public health considerations about resource allocation and striking a balance between individual benefit and public good. We consider sexual disinhibition in the context of private prescriptions, and conclude that only unjustified AIDS-exceptionalism or inappropriate moralism about sex supports thinking that PrEP raises new ethical problems. This negative conclusion is significant in a context where supposed ethical concerns about PrEP have been raised, and in the context of HIV exceptionalism. (shrink)

In ‘Freedom and Resentment,' Strawson argues that we cannot separate holding people morally responsible for their actions from specific emotional responses, which he calls reactive attitudes, which we are disposed towards in response to people's actions. Strawson's view might pose problems for forgiveness, in which we choose to overcome reactive attitudes like resentment without altering the judgments that make them appropriate. I present a detailed analysis of reactive attitudes, which I use both to defend Strawson's account of the connection between (...) these states and responsibility, and to show how we can fit forgiveness into this account.

ABSTRACT In this paper I respond to Fricker’s paradigm-based account of forgiveness, which aims to integrate two seemingly different versions of responses to wrongdoing—conditional forgiveness (what Fricker calls ‘Moral Justice Forgiveness’) and unconditional forgiveness (what Fricker calls ‘Gifted Forgiveness’)—into one explanatory order, as well as, she argues, showing the second to be derivative and parasitic on the basic functioning of the first, and more contingent. My aim is to endorse and draw on Fricker’s paradigm-based strategy and the way it enables (...) us to present a unified account, to endorse her view that both gifted and conditional forgiveness are versions of one loosely unified phenomenon, but to argue for the reverse account of the order of conceptual priority. I will argue that gifted forgiveness is the paradigm, and that once we understand what it is and its role we can see why and how forgiveness also makes sense as something offered in response to a wrongdoer’s remorse, but that this latter form of forgiveness retains an aspect of being something essentially gifted.

One of Kant’s central central claims in the Critique of Pure Reason is that we cannot have knowledge of things as they are in themselves. This claim has been regarded as problematic in a number of ways: whether Kant is entitled to assert both that there are things in themselves and that we cannot have knowledge of them, and, more generally, what Kant’s commitment to things in themselves amounts to. A number of commentators deny that Kant is committed to there (...) actually being an aspect of reality which we cannot cognise; they argue that he is committed merely to the idea that we cannot avoid the concept of things as they are in themselves. I will argue in this paper that while transcendental idealism is partly an epistemological position, it is also partly a metaphysical position, and in specific, that Kant is committed to the claim that the things we cognise have, in addition to the way they appear to us, a nature that is independent of us, which we cannot cognise.
