This book examines the origins and subsequent evolution of multicellularity. The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve.

Cost-benefit analysis is a widely used governmental evaluation tool, though academics remain skeptical. This volume gathers prominent contributors from law, economics, and philosophy for discussion of cost-benefit analysis, specifically its moral foundations, applications and limitations. This new scholarly debate includes not only economists, but also contributors from philosophy, cognitive psychology, legal studies, and public policy who can further illuminate the justification and moral implications of this method and specify alternative measures. These articles originally appeared in the Journal of Legal Studies. (...) Contributors: - Matthew D. Adler - Gary S. Becker - John Broome - Robert H. Frank - Robert W. Hahn - Lewis A. Kornhauser - Martha C. Nussbaum - Eric A. Posner - Richard A. Posner - Henry S. Richardson - Amartya Sen - Cass R. Sunstein - W. Kip Viscusi. (shrink)

Prioritarianism is an ethical theory that gives extra weight to the well-being of the worse off. In contrast, dominant policy-evaluation methodologies, such as benefit-cost analysis, cost-effectiveness analysis, and utilitarianism, ignore or downplay issues of fair distribution. Based on a research group founded by the editors, this important book is the first to show how prioritarianism can be used to assess governmental policies and evaluate societal conditions. This book uses prioritarianism as a methodology to evaluate governmental policy across a variety of (...) policy domains: taxation, health policy, risk regulation, education, climate policy, and the COVID-19 pandemic. It is also the first to demonstrate how prioritarianism improves on GDP as an indicator of a society's progress over time. Edited by two senior figures in the field with contributions from some of the world's leading economists, this volume bridges the gap from the theory of prioritarianism to its practical application.

This Article provides a comprehensive, critical overview of proposals to use happiness surveys for steering public policy. Happiness or “subjective well-being” surveys ask individuals to rate their present happiness, life-satisfaction, affective state, etc. A massive literature now engages in such surveys or correlates survey responses with individual attributes. And, increasingly, scholars argue for the policy relevance of happiness data: in particular, as a basis for calculating aggregates such as “gross national happiness,” or for calculating monetary equivalents for non-market goods based (...) on coefficients in a happiness equation. But is individual well-being equivalent to happiness? The happiness literature tends to blur or conflate important concepts: well-being, subjective well-being, happiness, utility, satisfaction. A preference-realization account of well-being denies the equivalence of happiness and welfare, since someone can have preferences for non-mental attributes, such as health, autonomy, goal-fulfillment, knowledge or the quality of her relationships. It is critical, therefore, to differentiate two potential policy roles for happiness surveys. First, the survey response may provide prima facie evidence of the respondent’s preference-utility: the extent to which her preferences are realized. Second, it may indicate her experience-utility: the quality of her mental states. The Article clarifies these two, very different, ideas. It then criticizes, in turn, the preference-utility and the experience-utility defenses of the policy relevance of happiness surveys. Enthusiasm about happiness is premature. (shrink)

A narrowly person-affecting (NPA) axiology is an account of the moral ranking of outcomes such that the comparison of any two outcomes depends on the magnitude and weight of individuals’ well-being gains and losses between the two. This article systematically explores NPA axiology. It argues that NPA axiology yields an outcome ranking that satisfies three fundamental axioms: Pareto, Anonymity and, plausibly, Pigou-Dalton. The axiology is neutral to non-well-being considerations (desert); and (assuming well-being measurability) leads to the Repugnant Conclusion (RC). In (...) short, NPA axiology provides a grounding for Paretian, equity-regarding welfarism, albeit one that includes the RC. (shrink)

In this paper I critique the concept of social groups deployed by Iris Marion Young in her well-known theory of the five faces of oppression. I contend that Young’s approach to conceptualizing social groups creates arbitrary and inconsistent categories, essentializes certain groups, and fails to take seriously the complexity of pluralism. I propose that Margaret Gilbert’s work in social metaphysics provides a more philosophically robust account of social groups that serves as a helpful corrective to Young’s approach. Gilbert’s account of (...) “we”-ness, as well as her theory of the nature of individuals and collectivities, provides a helpful vantage point for critiquing Young’s project and its emphasis on the social process of differentiation in the formation of social groups.

Written for his brother Benedictine monks around 1077, Anselm's Proslogion is perhaps the best-known partially-read book of the Middle Ages. Many readers are familiar only with Anselm's well-known argument for God's existence in Chapters 2-4, which is often called the "ontological argument," a misleading appellation coined centuries later by Immanuel Kant. In this argument Anselm begins with the thought of "something than which nothing greater is able to be thought," and subsequently he leads the reader to see that such a (...) reality necessarily exists and cannot be thought not to be. This argument - which is, to be sure, crucial to the work constitutes - but a small portion of the whole. Preceding it is a profound but oft-overlooked opening chapter in which Anselm contemplates his all-too-human condition and disposes the reader to receive aptly his argument for God's existence in the next three chapters. And following this argument are 20 chapters in which Anselm artfully unfolds the depth and breadth of God's true existence as that than which nothing greater is able to be thought, showing God to be (among other things) able-to-sense, pity-hearted, just, good, and uncircumscribed. Indeed, if the reader is willing to give himself over to the work as whole, he will be compelled, under Anselm's deft guidance, to "endeavor to straighten up his mind toward contemplating God," which is how Anselm describes his own role in the work in his prefatory remarks. This edition provides a faithful yet readable English rendering of the whole Proslogion, the objections raised to Anselm's argument by his contemporary Gaunilo, and Anselm's replies to those objections. (After responding to Gaunilo, Anselm himself requested that these objections and replies be included in subsequent editions of the Proslogion.) This edition also includes an introduction that contextualizes the Proslogion within the monastic, pre-Scholastic age in which it first made its appearance. In addition, by means of notes and commentary, this edition articulates how to contextualize Anselm's famous argument in the Proslogion as a whole and in light of his replies to Gaunilo, how to appreciate the artistry whereby Anselm knit the Proslogion together into a coherent and concise unity, and how the work may be taught effectively to interested students. These features set this affordable English edition of the Proslogion apart from those currently available, which too often fail to capture accurately the beauty of Anselm's prose, which often treat the work through the lens of either later Scholasticism or contemporary analytic philosophy of religion, and which take little note of the craftsmanship whereby Anselm constructed this masterfully integrated work that is remembered too often for too few of its 24 chapters. Matthew Walz has taught in the interdisciplinary program at Thomas Aquinas College in California, and since 2008 he has been a professor in the Philosophy Department of the University of Dallas.

The social and ecological crises of the twenty-first century represent a failure of the techno-industrial way of living and knowing. It has become apparent that we need both a new mythos and a new science. In this essay, I draw attention to the important epistemological and cosmological implications of enactivism, a still emerging paradigm within the life sciences. Guided by the insights of the enactive paradigm, I offer a new story of human origins and destiny in an attempt to contribute (...) to a more livable future for our species and the rest of the community of life on Earth.

Traditionally, Aristotle is held to believe that philosophical contemplation is valuable for its own sake, but ultimately useless. In this volume, Matthew D. Walker offers a fresh, systematic account of Aristotle's views on contemplation's place in the human good. The book situates Aristotle's views against the background of his wider philosophy, and examines the complete range of available textual evidence. On this basis, Walker argues that contemplation also benefits humans as perishable living organisms by actively guiding human life activity, (...) including human self-maintenance. Aristotle's views on contemplation's place in the human good thus cohere with his broader thinking about how living organisms live well. A novel exploration of Aristotle's views on theory and practice, this volume will interest scholars and students of both ancient Greek ethics and natural philosophy. It will also appeal to those working in other disciplines including classics, ethics, and political theory. (shrink)

In the nineteenth century, natural theology was ‘natural’ because the evidence was taken from direct observation of the natural world, or from observations made in the increasingly specialised settings of science. It was ‘theological’ because such evidence was interpreted in light of the attributes of God laid out in the Bible and in Christian doctrine. However, the extent to which the evidence of revelation was augmented or superseded by the facts provided by reason varied between authors. This chapter discusses how (...) different authors structured their design arguments, and shows that design arguments were increasingly recalibrated to incorporate new scientific evidence. But the basic premise of a theistically designed world also remained widely accepted by scientists and the reading public alike at the dawn of the twentieth century. (shrink)

In counterfactual cases of discrimination, an agent would have treated someone worse had circumstances been different such that instead of being a member of her actual group, she was a member of some other group. The case for considering such cases to be genuine cases of discrimination is bolstered by the fact that we are inclined to say that cases where an agent would have treated someone better had she been a member of another group are discriminatory. But I argue (...) that the cases are relevantly different: in one kind of case, but not the other, a person is harmed. I then consider and reject a number of objections to this suggestion. (shrink)

Can constitutional rights be both personal and rule-dependent? Can it be true of constitutional adjudication (1) that a constitutional litigant must assert rights, and yet also (2) that the viability of a constitutional challenge depends (or sometimes depends) on whether a particular type of legal rule, for example, a discriminatory or poorly tailored rule, is in force?

Prior to recent decades, the United States Supreme Court often invoked the political question doctrine to avoid deciding controversial questions of individual rights. 1 By the 1970s and 1980s, standing limits traced to Article IIIs arsenal of threshold decision making, 3 in the last decade the Court has turned with increasing frequency to the distinction between facial and as-applied challenges to perform the gatekeeping function. However, although there is a considerable body of scholarship concerning the conventional justiciability doctrines, scholars have (...) only recently begun to address the range of questions implicated by the Courtand they have generally focused on narrow doctrinal questions about the proper treatment of discrete rights such as abortion, free exercise of religion, and freedom of speech. The papers in this issue of LegalTheory and the next view these issues in a broader jurisprudential context. (shrink)

In this paper I respond to Robert Taylor's argument that a Rawlsian framework does not support strong affirmative action programs. The paper makes three main arguments. The first disputes Taylor's claim that strong AA would not be needed in ideal conditions. Private racial discrimination, I suggest, might still exist in such conditions, so strong AA might be needed there. The second challenges Taylor's claims that pure procedural justice constrains Rawlsian nonideal theory. I argue that this rests on a fetishizing of (...) pure procedural justice that is absent from Rawls's work. I also show that a revised formulation of Taylor's concern here also fails. My third argument makes a positive Rawlsian case for strong AA in nonideal conditions that builds on a Taylor concession. Taylor suggests that the goal of nonideal theory is to create a world in which ideal theory can be applied. My argument begins by showing that another permissible goal of Rawlsian nonideal theory is to ameliorate injustice. I then argue that Rawls's contractualist framework supports the strongest forms of AA when category 3 interventions are blocked. (shrink)

:Preference-aggregation problems arise in various contexts. One such context, little explored by social choice theorists, is metaethical. ‘Ideal-advisor’ accounts, which have played a major role in metaethics, propose that moral facts are constituted by the idealized preferences of a community of advisors. Such accounts give rise to a preference-aggregation problem: namely, aggregating the advisors’ moral preferences. Do we have reason to believe that the advisors, albeit idealized, can still diverge in their rankings of a given set of alternatives? If so, (...) what are the moral facts when the advisors do diverge? These questions are investigated here using the tools of Arrovian social choice theory. (shrink)

In the recent history of psychology and cognitive neuroscience, the notion of habit has been reduced to a stimulus-triggered response probability correlation. In this paper we use a computational model to present an alternative theoretical view (with some philosophical implications), where habits are seen as self-maintaining patterns of behavior that share properties in common with self-maintaining biological processes, and that inhabit a complex ecological context, including the presence and influence of other habits. Far from mechanical automatisms, this organismic and self-organizing (...) concept of habit can overcome the dominating atomistic and statistical conceptions, and the high temporal resolution effects of situatedness, embodiment and sensorimotor loops emerge as playing a more central, subtle and complex role in the organization of behavior. The model is based on a novel “iterant deformable sensorimotor medium” (IDSM), designed such that trajectories taken through sensorimotor-space increase the likelihood that in the future, similar trajectories will be taken. We couple the IDSM to sensors and motors of a simulated body and environment and show that under certain conditions, the IDSM forms self-maintaining patterns of activity that operate across the IDSM, the body, and the environment. We present various environments and the resulting habits that form in them. The model acts as an abstraction of habits at a much needed sensorimotor “meso-scale” between microscopic neuron-based models and macroscopic descriptions of behavior. Finally, we discuss how this model and extensions of it can help us understand aspects of behavioral self-organization, historicity and autonomy that remain out of the scope of contemporary representationalist frameworks.

The COVID-19 crisis has forced a difficult trade-off between limiting the health impacts of the virus and maintaining economic activity. Welfare economics offers tools to conceptualize this trade-off so that policy-makers and the public can see clearly what is at stake. We review four such tools: the Value of Statistical Life (VSL); the Value of Statistical Life Years (VSLYs); Quality-Adjusted Life-Years (QALYs); and social welfare analysis, and argue that the latter are superior. We also discuss how to choose policies that (...) differentially affect people’s wellbeing. We argue in favor of evaluating policies using a Social Welfare Function (SWF), which evaluates the possible distributions of wellbeing across individuals that may result from a policy. Such a function, we argue, should regard increases in the wellbeing of the less well-off as especially valuable. We then use a model to illustrate how such a framework can help evaluate two broad policy types in response to the pandemic: eradication of the virus, and more lenient control of the spread. Our model reveals how such evaluations depend on many empirical facts but also on key value judgments about the relative importance of health and on the extent of special concern for the worse off. The purpose of this brief is not to make precise recommendations, as conditions vary widely across countries and over time, but to provide a methodology. (shrink)

This paper argues that the concept and role of ‘institutional racism’ in contemporary discussions of race should be reconsidered. It starts by distinguishing between ‘intrinsic institutional racism’, which holds that institutions are racist in virtue of their constitutive features, and ‘extrinsic institutional racism’, which holds that institutions are racist in virtue of their negative effects. It accepts intrinsic institutional racism, but argues that a ‘disparate impact’ conception of extrinsic conception faces a number of objections, the most serious being that it (...) has no plausible account of what it is that makes extrinsically racist institutions racist. It also argues that claims about the explanatory indispensability of institutional racism are overstated (individual racism is at least as important), critiques structural approaches to racial inequality, and suggests that there is reason to doubt whether institutional reform can provide us with all that morality may require in the racial domain.

This paper builds upon, but substantially revises, John Harsanyi's concept of ‘extended preferences’. An individual ‘history’ is a possible life that some person (a subject) might lead. Harsanyi supposes that a given spectator, formulating her ethical preferences, can rank histories by empathetic projection: putting herself ‘in the shoes’ of various subjects. Harsanyi then suggests that interpersonal comparisons be derived from the utility function representing spectators’ (supposedly common) ranking of history lotteries. Unfortunately, Harsanyi's proposal has various flaws, including some that have (...) hitherto escaped scholarly attention. In particular, it ignores the limits of personal identity. If the subject has welfare-relevant attributes that the spectator cannot acquire without changing who she is, full empathetic identification of the latter with the former becomes impossible. This paper proposes instead to usesympathyas the attitude on a spectator's part that allows us to make sense of her extended preferences. Sympathy – an attitude of care and concern – is a psychological state quite different from empathy. We should also allow for hetereogeneity in spectators’ extended preferences. Interpersonal comparisons emerge from a plurality of sympathetic spectators, not (as per Harsanyi) from a common empathetic ranking. (shrink)

Current thinking and talk about race uses ‘racist’ for virtually everything that goes wrong in the domain of race. This paper examines the relationship between racial justice, racial discrimination and racism to argue for a more pluralistic approach to race-related ills. Such an approach provides the tools we need to understand an important if relatively neglected source of racial injustice, and does much to illuminate some race-related disputes. It starts by arguing that racial justice is a surprisingly limited ideal, and (...) then suggests understanding ‘racial discrimination’ in a minimal way. From there it is argued that while racial discrimination is necessary for racial injustice, the same is not true for racism. (shrink)

Complex life cycles are common in the eukaryotic world, and they complicate the question of how to define individuality. Using a bottom-up, gene-centric approach, I consider the concept of fitness in the context of complex life cycles. I analyze the fitness effects of an allele on different biological units within a complex life history and how these effects drive evolutionary change within populations. Based on these effects, I attempt to construct a concept of fitness that accurately predicts evolutionary change in (...) the context of complex life cycles. (shrink)

: Philosophers in the Indian and Western traditions have developed and defended a range of sophisticated accounts of self-awareness. Here, four of these accounts are examined, and the arguments for them are assessed. Theories of self-awareness developed in the two traditions under consideration fall into two broad categories: reflectionist or other-illumination theories and reflexivist or self-illumination theories. Having assessed the main arguments for these theories, it is argued here that while neither reflectionist nor reflexivist theories are adequate as traditionally formulated (...) and defended, the approaches examined here give important insights for the development of amore adequate contemporary account of self-awareness.

Anselm’s 'Proslogion' is, as he says in its Preface, 'unum argumentum', a single line of reasoning, that builds toward the following: “that God is truly,” “that he is the highest good who needs no other,” and that he is the one “whom all things need so that they may be and may be well.” This paper attempts to shed light on how Anselm carries out the threefold task that he sets for himself and way in which his procedure brings unity (...) to the work. Although I do not provide a full account of the unity of the 'Proslogion', I lay the groundwork for such an account by reflecting on the 'Proslogion' in light of the 'Symposium', with a view to bringing a pattern of thinking present in Plato’s work to bear on the 'Proslogion'—an intertextual approach that illuminates aspects of Anselm’s thinking and reveal the rich Platonic and Neoplatonic tradition within which he was working. In the 'Symposium', one discerns a pattern of thinking that consists of three “moments”: a comic moment, a tragic moment, and a philosophic moment. To follow this pattern in one’s inquiry is, as Socrates suggests, to practice 'ta erôtica', “erotics,” the art of erotic thinking. Familiarity with this pattern of erotic thinking helps make sense of Anselm’s thinking in the 'Proslogion', and in this paper I reveal how this is so. (shrink)

The restructuring of the healthcare marketplace has exerted pressure directly and indirectly on clinical ethics programs. The fiscal orientation and emphasis on efficiency, outcome measures, and cost control have made it increasingly difficult to communicate arguments in support of the existence or growth of ethics programs. In the current marketplace, arguments that rely on the claim that ethics programs protect patient rights or assist in the professional formation of practitioners often result in minimal levels of funding and preclude program growth. (...) Where ethics programs could once sustain themselves on goodwill alone and values arguments in an expanding healthcare market they are now encountering—at least by anecdotal reports—cutbacks and even elimination. To respond to these challenges, we offer an economic model that can be used to demonstrate the “value” of an institutionally based ethics program. (shrink)

Sunstein aims to provide a nonsectarian account of moral heuristics, yet the account rests on a controversial meta-ethical view. Further, moral theorists who reject act consequentialism may deny that Sunstein's examples involve moral mistakes. But so what? Within a theory that counts consequences as a morally weighty feature of actions, the moral judgments that Sunstein points to are indeed mistaken, and the fact that governmental action at odds with these judgments will be controversial doesn't bar such action.

If there is a “basic structure objection” to G.A. Cohen’s incentive critique of Rawls, then there is also a BSO to claims that private racial discrimination thwarts social justice by reducing the opportunity of its targets. In this paper, I take up the debate about the site or purview of justice and discuss it with reference to the case of race. I argue that the dispute about the site of justice has been wrongly understood as a dispute about the substantive (...) requirements of justice instead of as a dispute about where it is appropriate to apply considerations of justice.

This chapter offers a complete account of Aristotle’s underexplored treatment of the virtue of wittiness (eutrapelia) in Nicomachean Ethics IV.8. It addresses the following questions: (1) What, according to Aristotle, is this virtue and what is its structure? (2) How do Aristotle’s moral psychological views inform Aristotle’s account, and how might Aristotle’s discussions of other, more familiar virtues, enable us to understand wittiness better? In particular, what passions does the virtue of wittiness concern, and how might the virtue (and its (...) attendant vices) be related to the virtue of temperance (and its attendant vices)? (3) How does wittiness, as an ethical virtue, benefit its possessor? (4) How can Aristotle resolve some key tensions that his introducing a virtue of wittiness apparently generates for his ethics? In addition to exploring these questions, this chapter challenges some commonly accepted accounts of Aristotle’s views on the nature of the laughable. (shrink)

According to Michael Smith, in his book The Moral Problem, the following internalist claim is true: ‘‘If an agent judges it right to do something in certain circumstances, then the agent is either motivated to do that thing in the circumstances or is practically irrational.’’ He calls this claim the ‘‘practicality requirement on moral judgment,’’ and in his book tries to defend it against the amoralist challenge presented by David Brink. Brink famously argues against internalism on the grounds that it (...) ‘‘makes the amoralist conceptually impossible.’’ Amoralists are people who genuinely make moral judgments, remain unmoved with respect to their motivation, and yet do not suffer the relevant kinds of practical irrationality. They may judge, say, that it is right to donate one's old clothes to the Red Cross, but they not only fail to do so when the time comes, they are not motivated at all to do so when the time comes. Defenders of the practicality requirement, in contrast, claim that it is a ‘‘conceptual truth’’ that ‘‘agents who make moral judgments are motivated accordingly, at least absent weakness of will and the like.’’ Brink thinks amoralists are possible, and that since internalists deny the possibility, we should reject internalism in favor of externalism, which makes the moral motivation of judgers a matter of a contingent fact about them. -/- Smith's argument in The Moral Problem in defending the practicality requirement, then, is in essence to show that ‘‘it is impossible for there to be any amoralists.’’ In the argument to be considered here, he argues that externalists cannot offer an acceptable explanation for why the moral motivation of good people reliably follow their moral judgments. But we will see that Smith's defense of the practicality requirement loses its appeal once we see that it turns on an ambiguity in his use of the expression ‘‘good people.’’ Furthermore, easy examples show that, contrary what Smith says, people whose motivations reliably follow their moral judgments sometimes care only derivatively about that which they judge. Smith's later presentations of his argument also fail, for externalists need not offer a single explanation of the moral motivation of all whose motivation reliably follow their moral judgments.

In recent work in political philosophy there has been much discussion of two approaches to theorizing about justice that have come to be called ‘ideal theory’ and ‘non-ideal theory’. The distinction was originally articulated by Rawls, who defended his focus on ideal theory in terms of a supposed ‘priority’ of the latter over non-ideal theory. Many critics have rejected this claim of priority and in general have questioned the usefulness of ideal theory. In diagnosing the problem with ideal theory, they (...) have frequently fingered for blame the idealization it involves. In this paper I focus on one particular, much-discussed idealization—full compliance—in order to defend it. Focusing on the assumption, I argue that Rawls’s work is not ideal in the way that it is usually thought to be, is less ideal than is widely recognized, and became less ideal over time. I also argue that critics who in effect claim that it is not realistic enough simply fail to understand Rawls’s central motivation. Finally, I defend the assumption by arguing that there is an important sense in which all theories of justice must assume full compliance. Such an assumption, I argue, is needed if we are to have a plausible basis on which to judge the normative attractiveness of a theory. (shrink)

Decision theory seems to offer a very attractive normative framework for individual and social choice under uncertainty. The decisionmaker should think of her choice situation, at any given moment, in terms of a set of possible outcomes, that is, specifications of the possible consequences of choice, described in light of the decisionmaker's goals; a set of possible actions; and a "state set" consisting of possible prior "states of the world." It is this framework for choice which provides the foundation for (...) expected utility theory, as demonstrated in the work of Leonard Savage. Problems arise, however, when the decisionmaker is boundedly rational: when the mental process of thinking about outcomes, actions, and states is itself expensive and time consuming. In the case of the unboundedly rational decisionmaker, decision theory enjoins her to employ maximally specific outcomes; to consider all possible actions; and to use a set of mutually exclusive and collective exhaustive states, each of which is sufficiently finely specified so that each action, together with each state, yields one and only one maximally specific outcome. In the case of the boundedly rational decisionmaker, this procedure is either infeasible or, if feasible, irrational. This paper presents the problem of bounded rationality. It surveys possible solutions, none of which are found to be attractive. And it concludes by discussing the difficulties that the problem of bounded rationality poses for the welfarist program for legal scholarship presented by Louis Kaplow and Steven Shavell in their book, Fairness versus Welfare.

How should we make interpersonal comparisons of well-being levels and differences? One branch of welfare economics eschews such comparisons, which are seen as impossible or unknowable; normative evaluation is based upon criteria such as Pareto or Kaldor-Hicks efficiency that require no interpersonal comparability. A different branch of welfare economics, for example optimal tax theory, uses “social welfare functions” to compare social states and governmental policies. Interpersonally comparable utility numbers provide the input for SWFs. But this scholarly tradition has never adequately (...) explained the basis for these numbers. John Harsanyi, in his work on so-called “extended preferences,” advanced a fruitful idea. While an ordinary preference is a ranking of outcomes, an “extended preference” is a ranking of individual histories. To say that individual k has an extended preference for history over means something like the following: k prefers to have the attributes of individual i in outcome x, as opposed to having the attributes of individual j in outcome y. Harsanyi’s proposal was to endow individuals with “extended preferences”; to represent such preferences using “extended” utility functions; and to employ such functions, in turn, as the basis for interpersonal comparisons of well-being levels and differences. Harsanyi’s analysis, however, had various gaps and flaws. In this Article, I both diagnose these difficulties, and show how they can be remedied - yielding a viable account of interpersonal comparisons, one sufficient for the needs of the SWF approach.

The ‘Major Transitions in Evolution’ framework has emerged as the dominant paradigm for understanding the origins of life's hierarchical organization, but it has been criticized on the grounds that it lacks theoretical unity, that is, that the events included in the framework do not constitute a coherent category. I agree with this criticism, and I argue that the best response is to modify the framework so that the events it includes do comprise a coherent category, one whose members share fundamental (...) similarities. Specifically, I recommend defining major transitions as all those, and only those, events and processes that result in the emergence of a new population of evolutionary individuals. Two sorts of change will be required to achieve this. First, events and processes that do not meet this criterion, such as the origins of the genetic code and of human language, should be excluded. Second, events and processes that do meet the criterion, but which have generally been neglected, should be included. These changes would have the dual benefits of making MTEs a philosophically coherent category and of increasing the sample size on which we may infer trends and general principles that may apply to all MTEs.
