In an age of constitutional revolutions and reforms, theory and practice are moving in opposite directions. As a matter of constitutional practice, human dignity has emerged in jurisdictions around the world as the organizing idea of a groundbreaking paradigm. By reconfiguring constitutional norms, institutional structures and legal doctrines, this paradigm transforms human dignity from a mere moral claim into a legal norm that persons have standing to vindicate. As a matter of constitutional theory, however, human dignity remains an enigmatic idea. (...) Some explicate its meaning in abstraction from constitutional practice, while others confine themselves to less exalted ideas. The result is a chasm that separates constitutional practice from a theory capable of justifying its innovations and guiding its operation. By expounding the connection between human dignity and the constitutional practices that justify themselves in its light, Jacob Weinrib brings the theory and practice of constitutional law back together.

In legal orders around the world, commitments to democracy, liberalism and constitutionalism are increasingly eroding. Although political and constitutional theorists often lament this trend, they invariably adopt frameworks that are indifferent to these commitments. My aims in this article are both critical and constructive. As a critical matter, I will expose the indifference of the leading political and constitutional theories to the emergence, maintenance and refinement of liberal democratic constitutional orders. As a constructive matter, I will draw on Immanuel Kant’s (...) constitutional theory to explain why realizing such a form of governance is a public duty and why receding from it is a public wrong.

Kant's political philosophy draws a distinction between 'passive' citizens who are merely protected by the law and 'active' citizens who may also contribute to it. Although the distinction between passive and active citizens is often dismissed by scholars as an 'illiberal and undemocratic' relic of eighteenth century prejudice, the distinction is found in every democracy that distinguishes between mere inhabitants -- such as tourists and guestworkers -- and enfranchised citizens. The purpose of this essay is both interpretive and suggestive. First, (...) I will argue that Kant's mature distinction between active and passive citizens follows from an institutional deficiency in the the developing state rather than the natural deficiency of passive citizens, as Kant's critics have alleged. Second, I will draw on systematic features of Kant's political thought in order to claim that the state has a duty to create the institutional conditions of universal active citizenship. (shrink)

If Kant’s theory of justice is known for one thing, it is for offering a vision of a perfectly just society that is utterly disconnected from the imperfect societies that we occupy. The purity of Kant’s account has attracted criticism from those who claim that if a theory of justice is to be practical, it must offer more than a vision of a perfectly just society. It must also explain how existing societies mired in injustice are to be brought into (...) ever-closer conformity with the ideal that justice prescribes. In this essay, I will argue that this is exactly what Kant’s mature legal and political theory offers. To discern this feature of Kant’s theory, a neglected component must be integrated into his broader framework. This component is what Kant refers to in Toward Perpetual Peace as a permissive law of public right. (shrink)

If there is one point on which defenders and critics of the doctrine of proportionality agree, it is that Dworkin's rights as trumps model stands as a radical alternative to the doctrine. Those who are sympathetic to proportionality reject the rights as trumps model for failing to acknowledge that there are conditions under which a right may be justifiably infringed. In turn, those who regard rights as trumps reject the doctrine of proportionality for failing to take rights seriously. This paper (...) argues that each of these views is mistaken. On the one hand, Dworkin's rights as trumps model elides with a prominent version of the proportionality doctrine. On the other, this version takes rights seriously. (shrink)

In his ‘On a Supposed Right to Lie from Philanthropy’ Kant makes the astonishing claim that one is not entitled to lie even to save a friend from a murderer. This claim has been an embarrassment for Kant's defenders and an indication of Kant's excessive rigour for his detractors. Responses to SRL fall into three main groups. The first of these groups, that of Kant's critics, claim that SRL demonstrates that Kant's ethical views are so rigorous that they become abhorrent (...) in practice. The second group, Kant's defenders, argues that Kant's conclusions in SRL do not follow from his own ethical principles. The third group, made up of scholars who are generally sympathetic to Kant's position, attempts to explain why a liar is responsible for all the bad consequences that follow from his act by providing an account of Kant's theory of imputation.

In Dimensions of Private Law, Professor Stephen Waddams describes the obstacles that an adequate classification of private law must overcome. The purpose of this essay is to offer a theoretical account of legal classification that explains how these obstacles can be overcome and what the resulting classification of private law might look like. I begin with the catalogue of obstacles that Waddams presents and argue that, because they are rooted in misconceptions about the classificatory project, they pose no threat to (...) an adequate conception of legal classification. In search of such a conception, I consider how three great legal theorists – Aristotle, Kant, and Hegel – answer three fundamental classificatory questions about private law. First, what is the unitythat underlies the seemingly chaotic array of legal instances? Second, what is the principle of differentiationthat applies to this unity? Third, how are legalinstancessubsumed under this differentiated unity? The focus of this essay is the enduring significance of Kant’s conception of legal classification, which provides an alternative to Waddams’ conception and offers a set of coherent answers to the fundamental classificatory questions. In contrast, both Aristotle and Hegel respond to the fundamental classificatory questions by providing a conception of the unity of private law that fails to cohere with their ensuing accounts of its differentiation.

Panpsychism is a solution to the mind-body problem that presumes that consciousness is a fundamental aspect of reality instead of a product or consequence of physical processes (i.e., brain activity). Panpsychism is an elegant solution to the mind-body problem: it effectively rids itself of the explanatory gap materialist theories of consciousness suffer from. However, many theorists and experimentalists doubt panpsychism can ever be successful as a scientific theory, as it cannot be empirically verified or falsified. In this paper, I present (...) a panpsychist model based on the controversial idea that consciousness may be a so called higher physical dimension. Although this notion seems outrageous, I show that the idea has surprising explanatory power, even though the model (as most models) is most likely wrong. Most importantly, though, it results in a panpsychist model that yields predictions that can be empirically verified or falsified. As such, the model's main purpose is to serve as an example how a metaphysical model of consciousness can be specified in such a way that they can be tested in a scientifically rigorous way.

This article examines how deduction preserves certainty and how much certainty it can preserve according to Descartes’s Rules for the Direction of the Mind. I argue that the certainty of a deduction is a matter of four conditions for Descartes. First, certainty depends on whether the conjunction of simple propositions is composed with necessity or contingency. Second, a deduction approaches the certainty of an intuition depending on how many “acts of conceiving” it requires and—third—the complexity or difficulty of the acts (...) of thinking, which is determined by the content of the thoughts and on external factors. Fourth, certainty depends on the intellectual aptitude of the person using the deduction. A deduction lacks certainty when it relies on memory such that it is not apprehended with immediacy. However, the mental capacity and speed of a mind can be increased by training the special mental faculties of perspicacity and discernment. Increasing one’s intellectual aptitude allows for more steps of a deduction to be inferred in fewer acts of conceiving, thereby helping preserve the certainty of a deduction. (shrink)

This chapter develops Moral Occasionalism, according to which moral facts are grounded in certain natural facts, which are called sub-moral grounds, and these sub-moral grounds influence us in such a way as to induce largely correct moral beliefs. Moral Occasionalism is designed to explain the correlation of moral beliefs with the moral facts—and to do so in a way that is consistent with non-interactionist views, according to which moral facts neither influence nor are influenced by moral beliefs. It is argued (...) that moral non-naturalists and others who are committed to non-interactionist views ought to be in the business of defending Moral Occasionalism. The chapter shows that Moral Occasionalism has major advantages over its chief non-interactionist rival, namely David Enoch’s “godless pre-established harmony” view. The chapter anticipates and responds to several objections. (shrink)

This volume is a study of the relationship between philosophy and faith in Søren Kierkegaard's Philosophical Fragments. It is also the first book to examine the role of Socrates in this body of writings, illuminating the significance of Socrates for Kierkegaard's thought. Jacob Howland argues that in the Fragments, philosophy and faith are closely related passions. A careful examination of the role of Socrates demonstrates that Socratic, philosophical eros opens up a path to faith. At the same time, the (...) work of faith - which holds the self together with that which transcends it - is essentially erotic in the Socratic sense of the term. Chapters on Kierkegaard's Johannes Climacus and on Plato's Apology shed light on the Socratic character of the pseudonymous author of the Fragments and the role of 'the god' in Socrates' pursuit of wisdom. Howland also analyzes the Concluding Unscientific Postscript and Kierkegaard's reflections on Socrates and Christ. (shrink)

Totalism is the view that one distribution of well-being is better than another just in case the one contains a greater sum of well-being than the other. Many philosophers, following Parfit, reject totalism on the grounds that it entails the repugnant conclusion: that, for any number of excellent lives, there is some number of lives that are barely worth living whose existence would be better. This paper develops a theory of welfare aggregation—the lexical-threshold view—that allows totalism to avoid the repugnant (...) conclusion, as well as its analogues involving suffering populations and the lengths of individual lives. The theory is grounded in some independently plausible views about the structure of well-being, identifies a new source of incommensurability in population ethics, and avoids some of the implausibly extreme consequences of other lexical views, without violating the intuitive separability of lives.

An astonishing volume and diversity of evidence is available for many hypotheses in the biomedical and social sciences. Some of this evidence—usually from randomized controlled trials (RCTs)—is amalgamated by meta-analysis. Despite the ongoing debate regarding whether or not RCTs are the ‘gold-standard’ of evidence, it is usually meta-analysis which is considered the best source of evidence: meta-analysis is thought by many to be the platinum standard of evidence. However, I argue that meta-analysis falls far short of that standard. Different meta-analyses (...) of the same evidence can reach contradictory conclusions. Meta-analysis fails to provide objective grounds for intersubjective assessments of hypotheses because numerous decisions must be made when performing a meta-analysis which allow wide latitude for subjective idiosyncrasies to influence its outcome. I end by suggesting that an older tradition of evidence in medicine—the plurality of reasoning strategies appealed to by the epidemiologist Sir Bradford Hill—is a superior strategy for assessing a large volume and diversity of evidence.

The standard view of "believes" and other propositional attitude verbs is that such verbs express relations between agents and propositions. A sentence of the form “S believes that p” is true just in case S stands in the belief-relation to the proposition that p; this proposition is the referent of the complement clause "that p." On this view, we would expect the clausal complements of propositional attitude verbs to be freely intersubstitutable with their corresponding proposition descriptions—e.g., "the proposition that p"—as (...) they are in the case of "believes." In many cases, however, intersubstitution of that-clauses and proposition descriptions fails to preserve truth value or even grammaticality. These substitution failures lead some philosophers to reject the standard view of propositional attitude reports. Others conclude that propositional attitude verbs are systematically ambiguous. I reject both these views. On my view, the that-clause complements of propositional attitude verbs denote propositions, but proposition descriptions do not. (shrink)

I defend a radical interpretation of biological populations—what I call population pluralism—which holds that there are many ways that a particular grouping of individuals can be related such that the grouping satisfies the conditions necessary for those individuals to evolve together. More constraining accounts of biological populations face empirical counter-examples and conceptual difficulties. One of the most intuitive and frequently employed conditions, causal connectivity—itself beset with numerous difficulties—is best construed by considering the relevant causal relations as ‘thick’ causal concepts. I (...) argue that the fine-grained causal relations that could constitute membership in a biological population are huge in number and many are manifested by degree, and thus we can construe population membership as being defined by massively multidimensional constructs, the differences between which are largely arbitrary. I end by showing that positions in two recent debates in theoretical biology depend on a view of biological populations at odds with the pluralism defended here. (shrink)

Some of a person's mental states have the power to represent real and imagined states of affairs: they have semantic properties. What Minds Can Do has two goals: to find a naturalistic or non-semantic basis for the representational powers of a person's mind, and to show that these semantic properties are involved in the causal explanation of the person's behaviour. In the process, this 1997 book addresses issues that are central to much contemporary philosophical debate. It will be of interest (...) to a wide range of readers in philosophy of mind and of language, cognitive science, and psychology. (shrink)

Perceptual experience supports the assignment of confidences in belief – doxastic confidences. To explain this fact, many philosophers appeal to Perceptual Indeterminacy, which holds that perceptual content can be more or less determinate. Others instead appeal to Perceptual Confidence, which says that perceptual experience supports doxastic confidences because it assigns confidences too. Morrison argues that a primary reason to favour Perceptual Confidence is that it is uniquely capable of accounting for bell-shaped doxastic confidence distributions; we call this the bell curve (...) objection to Perceptual Indeterminacy. Here we show that two recent defences of Perceptual Indeterminacy, due to Nanay and Raleigh and Vindrola, fail to adequately address the bell curve objection. But we also argue that all is not lost for proponents of Perceptual Indeterminacy. They can counter the bell curve objection by embracing a third view, which we call Perceptual Noise. (shrink)

Lara Buchak argues for a version of rank-weighted utilitarianism that assigns greater weight to the interests of the worse off. She argues that our distributive principles should be derived from the preferences of rational individuals behind a veil of ignorance, who ought to be risk averse. I argue that Buchak’s appeal to the veil of ignorance leads to a particular way of extending rank-weighted utilitarianism to the evaluation of uncertain prospects. This method recommends choices that violate the unanimous preferences of (...) rational individuals and choices that guarantee worse distributions. These results, I suggest, undermine Buchak’s argument for rank-weighted utilitarianism. (shrink)

Studies in experimental philosophy claim to document intuition variation. Some studies focus on demographic group-variation; Colaçoet al., for example, claim that age generates intuition variation regarding knowledge attribution in a fake-barn scenario. Other studies claim to show intuition variation when comparing the intuition of philosophers to that of non-philosophers. The main focus has been on documenting intuition variation rather than uncovering what underlying factor(s) may prompt such a phenomenon. We explore a number of suggested explanatory hypotheses put forth by Colaçoet (...) al., as well as an attempt to test Sosa's claim that intuition variance is a result of people ‘filling in the details’ of a thought experiment differently from one another. We show (i) that people respond consistently across conditions aimed at ‘filling in the details’ of thought experiments, (ii) that risk attitude does not seem relevant to knowledge ascription, (iii) that people's knowledge ascriptions do not vary due to views about defeasibility of knowledge. Yet, (iv) we find no grounds to reject that a large proportion of people appear to adhere to so-called subjectivism about knowledge, which may explain why they generally have intuitions about the fake-barn scenario that vary from those of philosophers.

Evidence hierarchies are widely used to assess evidence in systematic reviews of medical studies. I give several arguments against the use of evidence hierarchies. The problems with evidence hierarchies are numerous, and include methodological shortcomings, philosophical problems, and formal constraints. I argue that medical science should not employ evidence hierarchies, including even the latest and most-sophisticated of such hierarchies.

In a paper published in Psychological Review, Tyler Burge has offered a unified non-mentalistic account of a wide range of social cognitive developmental findings. His proposal is that far from attributing mental states, young children attribute to humans the same kind of internal generic states of sensory registration that biologists attribute to e.g. snails and ticks. Burge’s proposal deserves close attention: it is especially challenging because it departs from both the mentalistic and all the non-mentalistic accounts of the data so (...) far. Moreover Burge has been one of the leading philosophers of mind of the past 40 years and some of his writings on the objectivity of perception display a deep understanding of the relevance of science for sharpening our understanding of the mind. After taking a close look at the developmental evidence, in particular at false-belief studies, I argue that Burge’s, 409–434, 2018) account faces severe obstacles. To give one telling example: if young children can only attribute to others sensory registrations, then it is hard to explain the evidence showing that they respond differently to an agent’s ignorance and to her false belief.

A platitude that took hold with Kuhn is that there can be several equally good ways of balancing theoretical virtues for theory choice. Okasha recently modelled theory choice using technical apparatus from the domain of social choice: famously, Arrow showed that no method of social choice can jointly satisfy four desiderata, and each of the desiderata in social choice has an analogue in theory choice. Okasha suggested that one can avoid the Arrow analogue for theory choice by employing a strategy (...) used by Sen in social choice, namely, to enhance the information made available to the choice algorithms. I argue here that, despite Okasha’s claims to the contrary, the information-enhancing strategy is not compelling in the domain of theory choice. (shrink)

How should we choose between uncertain prospects in which different possible people might exist at different levels of wellbeing? Alex Voorhoeve and Marc Fleurbaey offer an egalitarian answer to this question. I give some reasons to reject their answer and then sketch an alternative, which I call person-affecting prioritarianism.

Two basic theses underlie this work. The first, the specificity theorem, signifies that logic is essentially concerned with specific events and not with universal and transcendent systems. The second, the interbehavioral theorem, implies that no matter how logic is defined, it entails a psychological dimension that must be taken into account.

According to asymmetric comparativism, it is worse for a person to exist with a miserable life than not to exist, but it is not better for a person to exist with a happy life than not to exist. My aim in this paper is to explain how asymmetric comparativism could possibly be true. My account of asymmetric comparativism begins with a different asymmetry, regarding the (dis)value of early death. I offer an account of this early death asymmetry, appealing to the (...) idea of conditional goods, and generalize it to explain how asymmetric comparativism could possibly be true. I also address the objection that asymmetric comparativism has unacceptably antinatalist implications. (shrink)

Aristotle is said to have held that any kind of actual infinity is impossible. I argue that he was a finitist (or "potentialist") about _magnitude_, but not about _plurality_. He did not deny that there are, or can be, infinitely many things in actuality. If this is right, then it has implications for Aristotle's views about the metaphysics of parts and points.

Amalgamating evidence of different kinds for the same hypothesis into an overall confirmation is analogous, I argue, to amalgamating individuals’ preferences into a group preference. The latter faces well-known impossibility theorems, most famously “Arrow’s Theorem”. Once the analogy between amalgamating evidence and amalgamating preferences is tight, it is obvious that amalgamating evidence might face a theorem similar to Arrow’s. I prove that this is so, and end by discussing the plausibility of the axioms required for the theorem.

The manifest appearance of function and purpose in living systems is responsible for the prevalence of apparently teleological explanations of organismic structure and behavior in biology. Although the attribution of function and purpose to living systems is an ancient practice, teleological notions are largely considered ineliminable from modern biological sciences, such as evolutionary biology, genetics, medicine, ethology, and psychiatry, because they play an important explanatory role. Historical and recent examples of teleological claims include the following: The chief function of the (...) heart is the transmission and pumping of the blood through the arteries to the extremities of the body. (Harvey 1616 [1928: 49]) The Predator Detection hypothesis remains the strongest candidate for the function of stotting [by gazelles]. (Caro 1986: 663) The geographic range of human malaria is much wider than the range of the sickle-cell gene. As it happens, other antimalarial genes take over the protective function of the sickle-cell gene in … other warm parts. (Diamond 1994: 83) Despite the substantial amount of data we now have on theropod dinosaurs, more information is necessary in order to determine the likelihood that early feathers served an adaptive function in visual display as opposed to other proposed adaptive functions such as thermoregulation. (Dimond et al. 2011: 62) The ubiquity of claims such as these raises the question: how should apparently teleological notions in biology be understood? Most post-Darwinian approaches attempt to naturalize teleology in biology, in opposition to nineteenth-century viewpoints which grounded it theologically. Nevertheless, biologists and philosophers have continued to question the legitimacy of teleological notions in biology. For instance, Ernst Mayr (1988), identified four reasons why teleological notions remain controversial in biology, namely that they are: vitalistic (positing some special ‘life-force’); requiring backwards causation (because goal-directed explanations seem to use future outcomes to explain present traits); incompatible with mechanistic explanation (because of 1 and 2); mentalistic (attributing the action of mind where there is none). A fifth complaint is that they are not empirically testable (Allen & Bekoff 1995). The current philosophical literature offers both Darwinian and non-Darwinian accounts of teleology in biology that aim to avoid these concerns. In this article, we hope to bring some clarity to the contemporary debates over the role of teleological notions in biology by sketching a taxonomy of the various accounts of biological function on offer (see Allen & Bekoff 1995 for a more comprehensive taxonomy that forms the basis of this presentation). We primarily focus on naturalistic accounts of biological function, since this is where we see the most lively and productive current debates (see, e.g., Garson 2016 for an extended survey). We also briefly discuss the notion of goal-directedness in section 2. (shrink)

Hastings Center Report, Volume 52, Issue 2, Page 10-14, March‐April 2022.

In the opening sections of his Foundations of Natural Right, Fichte argues that mutual recognition is a condition for the possibility of self-consciousness. However, the argument turns on the apparently unconvincing claim that, in the context of transcendental philosophy, conceptions of the subject as an isolated individual give rise to a vicious circle the resolution of which requires the introduction of a second rational being to ‘summon’ the first. In this essay, my aim is to present a revised account of (...) the opening arguments on which they are more convincing. In particular, I argue that the problem of a circle is genuine and may be seen to result from a relation of mutual dependence between agency and cognition which ensures that for an exercise of either capacity to take place, an exercise of the other would have already had to have taken place with the result that neither can occur. Moreover, the solution is successful. The summons prevents us from being driven around the circle once more because it is a ‘synthesis’ that reconciles the constraint to which I am subject as a cognizer of independently given objects and my freedom as a self-determining subject.

This article diagnoses and critiques pervasive forms of teleological thought about basic structures of political organization in modern and contemporary political thought: arguments that the sovereign state, the nation-state, or some variant of a cosmopolis both represents the unfolding of history’s moral logic and offers us full moral personhood, agency, and maturity. Despite the received wisdom that modern political thought broke with teleology, I argue that early modern social contract theory was deeply teleological. The emergence of the normatively self-contained sovereign (...) state from the state of nature represented both decisive historical-moral progress from the medieval European non-state polities and the possibility of true moral personhood, thanks to the unity of will and judgment created by a unified authority structure. The article then argues that this overattachment to unity, both as an historical culmination and as a prerequisite to full personhood, was carried over into subsequent nationalist and cosmopolitan thought, where we see over-moralizations of historical processes, excessive claims for the teleological causal force of moral progress, and critiques of the immaturity of those persons who do not live in the recommended political form. The article closes with a sustained critique of both historical and individual-moral teleologies of these sorts. (shrink)

Medical scientists employ ‘quality assessment tools’ (QATs) to measure the quality of evidence from clinical studies, especially randomized controlled trials (RCTs). These tools are designed to take into account various methodological details of clinical studies, including randomization, blinding, and other features of studies deemed relevant to minimizing bias and error. There are now dozens available. The various QATs on offer differ widely from each other, and second-order empirical studies show that QATs have low inter-rater reliability and low inter-tool reliability. This (...) is an instance of a more general problem I call the underdetermination of evidential significance. Disagreements about the strength of a particular piece of evidence can be due to different—but in principle equally good—weightings of the fine-grained methodological features which constitute QATs.

Reasons transmit. If one has a reason to attain an end, then one has a reason to effect means for that end: reasons are transmitted from end to means. I argue that the likelihood ratio (LR) is a compelling measure of reason transmission from ends to means. The LR measure is superior to other measures, can be used to construct a condition specifying precisely when reasons transmit, and satisfies intuitions regarding end-means reason transmission in a broad array of cases.

Millstein (2009) argues against conceptual pluralism with respect to the definition of “population,” and proposes her own definition of the term. I challenge both Millstein's negative arguments against conceptual pluralism and her positive proposal for a singular definition of population. The concept of population, I argue, does not refer to a natural kind; populations are constructs of biologists variably defined by contexts of inquiry.

Non-cognitive gadgets are fancy tools shaped to meet specific, local needs. Cecilia Heyes defines cognitive gadgets as dedicated psychological mechanisms created through social interactions and culturally, not genetically, inherited by humans. She has boldly proposed that many human cognitive mechanisms are gadgets. If true, these claims would have far-reaching implications for our scientific understanding of human social cognition. Here we assess Heyes’s cognitive gadget approach as it applies to mindreading. We do not think that the evidence supports Heyes’s thought-provoking thesis (...) that human children are taught to read minds the way they are taught to read words. We highlight a potential circularity lurking behind this analogy, and we explain why we are unpersuaded by Heyes’s anti-mentalistic proposal for handling data inconsistent with the gadget view, which others take to be evidence for mindreading in human infancy. We conclude that while human minds may well be filled with gadgets, mindreading is unlikely to be one of them. (shrink)
