Circalunar clocks, which allow organisms to time reproduction to lunar phase, have been experimentally proven but are still not understood at the molecular level. Currently, a new generation of researchers with new tools is setting out to fill this gap. Our essay provides an overview of classic experiments on circalunar clocks. From the unpublished work of the late D. Neumann we also present a novel phase response curve for a circalunar clock. These experiments highlight avenues for molecular work and (...) call for rigor in setting up and analyzing the logistically complex experiments on circalunar clocks. Re‐evaluating classic experiments, we propose that (1) circalunar clocks in different organisms will have divergent mechanisms and physiological bases, (2) they may have properties very different from the well‐studied circadian clocks and (3) they may have close mechanistic and molecular relations to seasonal rhythms and diapause.

This is the classic work upon which modern-day game theory is based. What began as a modest proposal that a mathematician and an economist write a short paper together blossomed, when Princeton University Press published Theory of Games and Economic Behavior. In it, John von Neumann and Oskar Morgenstern conceived a groundbreaking mathematical theory of economic and social organization, based on a theory of games of strategy. Not only would this revolutionize economics, but the entirely new field of scientific (...) inquiry it yielded--game theory--has since been widely used to analyze a host of real-world phenomena from arms races to optimal policy choices of presidential candidates, from vaccination policy to major league baseball salary negotiations. And it is today established throughout both the social sciences and a wide range of other sciences. (shrink)

This book represents the views of one of the greatest mathematicians of the twentieth century on the analogies between computing machines and the living human brain.

Jules Coleman, one of the world's leading philosophers of law, here presents his most mature work so far on substantive issues in legal theory and the appropriate methodology for legal theorizing. In doing so, he takes on the views of highly respected contemporaries such as Brian Leiter, Stephen Perry, and Ronald Dworkin.

The influence of emotion on episodic and autobiographical memory in schizophrenia was investigated. Using an experiential approach, the states of awareness accompanying recollection of pictures from the IAPS and of associated autobiographical memories was recorded. Results show that schizophrenia impairs episodic and autobiographical memories in their critical feature: autonoetic awareness, i.e., the type of awareness experienced when mentally reliving events from one’s past. Schizophrenia was also associated with a reduction of specific autobiographical memories. The impact of stimulus valence on memory (...) performance was moderated by clinical status. Patients with schizophrenia recognized more positive than negative pictures, and recalled more positive than negative autobiographical memories while controls displayed the opposite pattern. A hypothesis in terms of a fundamental executive deficit underlying these impairments is proposed. (shrink)

This book by one of America's preeminent legal theorists is concerned with the conflict between the goals of justice and economic efficiency in the allocation of risk, especially risk pertaining to safety. The author approaches his subject from the premise that the market is central to liberal political, moral, and legal theory. In the first part of the book, he rejects traditional "rational choice" liberalism in favor of the view that the market operates as a rational way of fostering stable (...) relationships and institutions within communities of individuals with broadly divergent conceptions of the good. However, markets are needed most where they are most difficult to create and sustain, and one way to understand contract law in liberal legal theory, according to Professor Coleman, is as an institution designed to reduce uncertainty and thereby make markets possible. Another target of this book is the prevalent view that tort law helps rectify market failures when transaction costs are too high to permit contracting. The author argues instead that tort law should be understood as a way of rectifying wrongful losses not inefficient exchanges. (shrink)

Next SectionIn emphasizing the importance of the separability thesis, legal philosophers have inadequately appreciated other philosophically important ways in which law and morality are or might be connected with one another. In this article, I argue that the separability thesis cannot shoulder the philosophical burdens that it has been asked to bear. I then turn to two issues of greater importance to jurisprudence. These are ‘the moral semantics of law’ and ‘the normativity of theory construction in jurisprudence’. The moral semantics (...) claim is that legal content is best understood as moral directives about what is to be done and who is to decide what is to be done. The problem is that legal positivists typically hold that only social facts contribute to the content of law, and it is hard to see how a positivist can hold both the social-facts claim and the moral-semantics claim. I argue that not only are the two claims consistent with one another, but that legal positivists must hold some version of the moral semantics claim if they are to make sense of the claim that legal reasons purport to be content-independent moral reasons for acting. In Section 3 of the article, I take up the question of whether theory construction in jurisprudence is normative or descriptive. This is hard to do in part because so little attention has been paid to correctly formulating the issue. I suggest a demanding test for descriptivism; namely, that an adequate analysis of law can be provided entirely in terms of its formal features. I then defend this claim against three arguments designed to show because governance by law is necessarily desirable or valuable that, we cannot characterize law without making reference to those values or to other material features of law. This constitutes a limited but powerful defence of descriptive jurisprudence. (shrink)

Research programs in empirical psychology from the past two decades have revealed implicit biases. Although implicit processes are pervasive, unavoidable, and often useful aspects of our cognitions, they may also lead us into error. The most problematic forms of implicit cognition are those which target social groups, encoding stereotypes or reflecting prejudicial evaluative hierarchies. Despite intentions to the contrary, implicit biases can influence our behaviours and judgements, contributing to patterns of discriminatory behaviour. These patterns of discrimination are obviously wrong and (...) unjust. But in remedying such wrongs, one question to be addressed concerns responsibility for implicit bias. Unlike some paradigmatic forms of wrongdoing, such discrimination is often unintentional, unendorsed, and perpetrated without awareness; and the harms are particularly damaging because they are cumulative and collectively perpetrated. So, what are we to make of questions of responsibility? In this article, we outline some of the main lines of recent philosophical thought, which address questions of responsibility for implicit bias. We focus on (a) the kind of responsibility at issue; (b) revisionist versus nonrevisionist conceptions of responsibility as applied to implicit bias; and (c) individual, institutional, and collective responsibility for implicit bias.

We explore the relationship between jurisprudential theories pertaining to the nature of law and semantic and metasemantic theories pertaining to the meaning of ‘law’ in the wake of Dworkin’s notorious Semantic Sting argument in Law’s Empire (HUP 1986). Along the way we delineate various aspects of the semantic and metasemantic underpinnings of ‘law’ as an artifact term and advance the general methodological point that jurisprudential inquiry is only negligibly constrained by the findings of semantic and metasemantic inquiry.

Philosophers who have written about implicit bias have claimed or implied that individuals are not responsible, and therefore not blameworthy, for their implicit biases, and that this is a function of the nature of implicit bias as implicit: below the radar of conscious reflection, out of the control of the deliberating agent, and not rationally revisable in the way many of our reflective beliefs are. I argue that close attention to the findings of empirical psychology, and to the conditions for (...) blameworthiness, does not support these claims. I suggest that the arguments for the claim that individuals are not liable for blame are invalid, and that there is some reason to suppose that individuals are, at least sometimes, liable to blame for the extent to which they are influenced in behaviour and judgment by implicit biases. I also argue against the claim that it is counter-productive to see bias as something for which individuals are blameworthy; rather, understanding implicit bias as something for which we are liable to blame could be constructive.

H.L.A. Hart'sThe Concept of Lawis the most important and influential book in the legal positivist tradition. Though its importance is undisputed, there is a good deal less consensus regarding its core commitments, both methodological and substantive. With the exception of an occasional essay, Hart neither further developed nor revised his position beyond the argument of the book. The burden of shaping the prevailing understanding of his views, therefore, has fallen to others: notably, Joseph Raz among positivists, and Ronald Dworkin among (...) positivism's critics. Dworkin, in particular, has framed, then reframed, the conventional understanding, not only of Hart's positivism, but of the terms of the debate between positivists and him. While standing on the sidelines, Hart witnessed the unfolding of not only a lively debate between positivists and Dworkin, but an equally intense one among positivists as to positivism's (and his) core claims. The most important debate has been between so-called inclusive and exclusive positivists: a debate as much about Hart's legacy as about the proper interpretation of legal positivism. (shrink)

Do participants in shared activity have mutual obligations to do their bit? This article shows this question has no one-size-fits-all answer and offers a pluralist account of the normativity of shared agency. The first part argues obligations to do one's bit have three degrees of involvement in shared activity. Such obligations might, obviously, bolster co-participants’ resolve to act as planned (degree 1). Less obviously, there also are higher and lower degrees of involvement. Obligations to do one's bit might provide our (...) agency-pooling mechanism. When they do, we act together by virtue of satisfying them (degree 2). Conversely, some shared activities involve no obligation (degree 0). In the second part, I argue shared agency theory is best served by a non-moralistic conception of obligation, one on which co-participants’ obligations need be neither strict-performance obligations, nor directed ones. Overall, my arguments suggest that we can choose how to coordinate normatively our shared activities. (shrink)

Suppose the prevailing distribution of property rights is unjust as determined by the relevant conception of distributive justice. You have far more than you should have under that theory and I have far less. Then I defraud you and in doing so reallocate resources so that our holdings ex post more closely approximate what distributive justice requires. Do I have a duty to return the property to you? There are many good reasons for requiring me to return to you what (...) I have taken. One is that while you may have no right in justice to all that you own, it does not follow that I do, or that I have a right to take it. Thus, requiring me to return the property to you is a way of recognizing that I had no right to take it from you in the first place. (shrink)

The term 'implicit bias' has very swiftly been incorporated into philosophical discourse. Our aim in this paper is to scrutinise the phenomena that fall under the rubric of implicit bias. The term is often used in a rather broad sense, to capture a range of implicit social cognitions, and this is useful for some purposes. However, we here articulate some of the important differences between phenomena identified as instances of implicit bias. We caution against ignoring these differences: it is likely (...) they have considerable significance, not least for the sorts of normative recommendations being made concerning how to mitigate the bad effects of implicit bias.

This essay is part of a larger project exploring the extent to which the market paradigm might be usefully employed to explain and in some instances justify nonmarket institutions. The focus of the market paradigm in this essay is the relationship between the idea of a perfectly competitive market and aspects of both the rationality of political association and the theory of collective choice. In particular, this essay seeks to identify what connections, if any, exist between one kind of market (...) account of the rationality of political association and one kind of market-based social choice rule. The market theory of political association I intend to discuss I call “market contractarianism,” and the collective choice rule whose relation to it I intend to explore is the unanimity rule. What, if anything, is the relationship between market contractarianism and the unanimity rule? (shrink)

Reactive emotion accounts hold that blameworthiness should be analyzed in terms of the familiar reactive emotions. However, despite the attractions of such views, we are not persuaded that blameworthiness is ultimately a matter of correctly felt reactive emotion. In this paper, we draw attention to a range of little-discussed considerations involving the moral significance of the passage of time that drive a wedge between blameworthiness and the reactive emotions: the appropriateness of the reactive emotions is sensitive to the passage of (...) time in ways that attributions of blameworthiness are not. There are a number of ways in which reactive emotion accounts might attempt to accommodate the moral significance of time, however. We consider the most important of these, but ultimately find them wanting. Accordingly, we conclude that the prospects for the reactive emotion accounts are bleak. Our argument, if successful, has a range of implications for legal theory, most importantly in providing a novel moral basis for statutes of limitations and in shedding light on new avenues in the theory of criminal law generally.

Our focus here is on whether, when influenced by implicit biases, those behavioural dispositions should be understood as being a part of that person’s character: whether they are part of the agent that can be morally evaluated.[4] We frame this issue in terms of control. If a state, process, or behaviour is not something that the agent can, in the relevant sense, control, then it is not something that counts as part of her character. A number of theorists have argued (...) that individuals do not have control, in the relevant sense, over the operation of implicit bias. We will argue that this claim is mistaken. We articulate and develop a notion of control that individuals have with respect to implicit bias, and argue that this kind of control can ground character-based evaluation of such behavioural dispositions.

Oedipus’s basic error was to have viewed evil as a problem, whereas he learns to his grief that it is actually a mystery, an irresolvable paradox, a natural contradiction between the mutually exclusive possibilities of self-determination and predetermination, between freedom of the will and divine omniscience. This is the quandary as it is perceived by philosophy and religion. In the domains of religion and theology Fate is indeed a mystery. Ill-equipped as I am to elucidate mysteries, I will move the (...) discussion to a firmer ground, where the concept of Fate is merely a problem, where scholars, those who “traffic in words,” as Goethe calls us, stand a fighting chance.1My major concerns will be: 1) to determine what ..

Last night I dived my beggar armDays deep in her breast that wore no heartFor me alone but only a rocked drumTelling the heart I broke of a good habitThat her loving, unfriendly limbsWould plunge my betrayal from sheet to skySo the betrayed might learn in the sun beamsOf the death in a bed in another country.1This poem, as far as I have been able to determine, has never been the object of any published critical commentary. The only help that (...) I have had in my reading of it has come from groups of students to whom I have regularly assigned it as a midterm paper, largely because I knew in advance that they would have to confront it entirely on their own. My interest in this text stems from its unique status as a poem.. (shrink)

A dissertation in the tradition of logical positivism includes a discussion of the functions and methods of philosophy and a critique of ethics and theology.

Research programs in empirical psychology over the past few decades have led scholars to posit implicit biases. This is due to the development of innovative behavioural measures that have revealed aspects of our cognitions which may not be identified on self-report measures requiring individuals to reflect on and report their attitudes and beliefs. But what does it mean to characterise such biases as implicit? Can we satisfactorily articulate the grounds for identifying them as bias? And crucially, what sorts of cognitions (...) are in fact being measured; what mental states or processes underpin such behavioural responses? In this paper, we outline some of the philosophical and empirical issues engaged when attempting to address these three questions. Our aim is to provide a constructive taxonomy of the issues, and how they interrelate. As we will see, any view about what implicit bias is may depend on a range of prior theoretical choices.

Twenty-four years remind the tears of my eyes.In the groin of the natural doorway I crouched like a tailorSewing a shroud for a journeyBy the light of the meat-eating sun.Dressed to die, the sensual strut begun,With my red veins full of money,In the final direction of the elementary townI advance for as long as forever is.1The first problem raised in this poem is the agrammatical status of the word remind, which in normal usage governs either a verbal or phrasal complement.

As every teacher of literature knows, obscure writing is not necessarily the most problematic kind to deal with. A sonnet by Donne or an equal number of lines by Dylan Thomas will handily fill the teaching hour. But what about that other kind of writing, the kind that imposes silence, not by its obvious difficulty but by its infuriating obviousness, the perfection of its form, the simplicity of its language, the transparency of its meaning? There is no trouble filling the (...) hour with Yeats’s Byzantium poems, but what about this one?The fascination of what’s difficultHas dried the sap out of my veins, and rentSpontaneous joy and natural contentOut of my heart.

The question of whether colour categorisation is determined by nontrivial constraints (i.e., universal neurophysiological properties of visual neurons) is an empirical issue concerning the organisation of the internal colour space. Rosch has provided psychological evidence that categories are organised around focal colours and that the organisation is universal; this commentary reconsiders that evidence.

Goldstein reported multiple cases of failure to categorise colours in patients that he termed amnesic or anomic aphasics. These patients have a particular difficulty in producing perceptual categories in the absence of other aphasic impairments. We hold that neuropsychological evidence supports the view that the task of colour categorisation is logically impossible without labels.

Evidence from aphasia is considered that leads to a distinction between abstract and concrete thought processes and hence for a distinction between rules and similarity. It is argued that perceptual classification is inherently a rule-following procedure and these rules are unable to be followed when a patient has difficulty with name comprehension and retrieval.
