In this paper, I show that, in a number of publications in the early 1950s, Margaret Macdonald argues that art does not admit of definition, that art is—in the sense associated with Wittgenstein—a family resemblance concept, and that definitions of art are best understood as confused or poorly expressed contributions to art criticism. This package of views is most typically associated with a famous paper by Morris Weitz from 1956. I demonstrate that Macdonald advanced that package prior to Weitz, indeed, (...) prior to any other philosopher of art of the period. Despite this, Macdonald’s contribution is nowhere to be found in the subsequent literature on the definition of art. In closing, I raise the prospect that Macdonald was in fact the primary influence on the development of Weitz’s critique of the definitional project. (shrink)

In this essay both the facts/values and facticity/normativity divides are considered from the perspective of global semiotics and with specific regard to the relationships between legal meaning and spatial scope of law’s experience. Through an examination of the inner and genetic projective significance of categorization, I will analyze the semantic dynamics of the descriptive parts comprising legal sentences in order to show the intermingling of factual and axiological/teleological categorizations in the unfolding of legal experience. Subsequently, I will emphasize the translational (...) and enactive cognitive disposition underlying the construction of the second premise of the so-called judiciary syllogism and thereby the untenability of the idea that ‘law makes its facts.’ Hence, I will try to bring to the fore the cultural pre-assumptions encapsulated in the positivistic and therefore also formalistic or analytical approaches to legal experience and the loss of their inner consistency when legal experience confronts the phases and major changes of global semiotics. Finally, I will strive to relativize the opposition between the positivist and non-positivistic theories of law in view of an understanding of legal experience focused not only, or at least not primarily, on what ‘law is’ but also on ‘how’ it unwinds through, and _in spite of_, environmental and semantic transformations.

Vicarious responsibility is a notoriously puzzling notion in normative reasoning. In this article we will explore two fundamental issues, which we will call the “explication problem” and the “justification problem”. The former issue concerns how vicarious responsibility can plausibly be defined in terms of other normative concepts. The latter issue concerns how ascriptions of vicarious responsibility can be justified. We will address these two problems by combining ideas taken from legal theory and moral philosophy. Our analysis will emphasise the importance (...) of the voluntary involvement of the normative parties considered liable in a relation with other normative parties who causally contributed to a prohibited state-of-affairs.

This paper reflects on the problem of endowing Artificial Intelligence with legal subjectivity, especially with regard to civil law. It is necessary to reject the myth that the criteria of legal subjectivity are sentience and reason. Arguing that AI may have potential legal subjectivity based on an analogy to animals or juristic persons suggests the existence of a single hierarchy or sequence of entities, organized according to their degree of similarity to human beings; also, that the place of an entity (...) in this hierarchy determines the scope of subjectivity attributed to it. Rather, it is participation or presence in social life, whatever the role, that is the true criterion of subjectivity. In addition, it is clear that even if AI is not currently a significant participant in social life, it will be in the nearest future. Despite the potential dangers associated with endowing AI with some kind of subjectivity, such a course is inescapable, and should be considered sooner rather than later. (shrink)

[full article, abstract in English; only abstract in Lithuanian] This paper proposes a new pragmatic interpretation of the Frege–Geach problem and presents a possible solution using a model of ascriptive legal language. The first section includes the definition of the Frege–Geach problem. In the second section, I analyze the content of Geach’s critical argument against prescriptivism in ethics. I discuss what Geach means by ascriptivism, why he mixes it with prescriptivism, and why a particular article by Herbert Hart became the (...) subject of criticism by Geach. The third section proposes a possible solution to the Frege–Geach problem based on the explication of the assertoric force of ascriptive legal utterances and the performativity of legal language.

This article claims that legal time has excluded and submerged an important sense of time inside structured time. Structured time has two forms. Each form of structured time identifies a beginning to a legal order (droit, Recht) as a whole. The one form has focussed upon a critical date. The critical date is exemplified by a basic text, such as the Constitution, or the judicially identified date of settlement, sovereignty or territorial control of a territory by the state. The second (...) form of structured time has begun with the judicial recognition of a value such as the rule of law, the protection of minorities, equal treatment, or due process of law. With the two forms of structured time, jurists have proceeded to identify a binding law. Such a law has been considered a rule, principle, doctrine or other intelligible standard. Once structured legal time has thus begun, events of legal relevance have been represented by jurists in a distinct phase or period of time. Each such a distinct period is parsed through reference to its named, or labelled, starting point and the latter, in turn and ultimately, with reference to the beginning of the very constitutional order as a whole. Legal justification and the conceptual structures of justification are presumed to follow suit. The article argues, however, that another sense of time, excluded and submerged inside structured time, is experienced. An experienced event, manifested as a discrete incident in experiential time, opens to a condition of the possibility of the existence of law. (shrink)

The interdisciplinary debate about the nature of expertise often conflates having expertise with either the individual possession of competences or a certain role ascription. In contrast to this, the paper attempts to demonstrate how different dimensions of expertise ascription are inextricably interwoven. As a result, a balanced account of expertise will be proposed that more accurately determines the closer relationship between the expert’s dispositions, their manifestations and the expert’s function. This finally results in an advanced understanding of expertise that views (...) someone as an expert only if she is undefeatedly disposed to fulfill a contextually salient service function adequately at the moment of assessment.

A number of philosophers in recent years have maintained that H. L. A. Hart inThe Concept of Lawpropounded an expressivist account of the semantics of the legal statements that are uttered from the internal viewpoint of the people who run the institutions of legal governance in any jurisdiction. Although the primary aim of this article is to attack the attribution of that semantic doctrine to Hart, the article will begin with some metaphysical matters—the matters of reductionism and naturalism—that often lie (...) behind the development of expressivist approaches to the semantics of normative discourse. After briefly exploring those metaphysical concerns (to which I will return later), the article will begin its main discussion by rehearsing the distinction between the semantics and the pragmatics of utterances. It will then delineate the doctrine of expressivism which the aforementioned philosophers have in mind when they ascribe that doctrine to Hart. Although I will make reference to a few such philosophers, I will focus chiefly on an article by Kevin Toh that has been the fountainhead of all the subsequent attributions of expressivism to Hart. As will be argued herein, Toh and like‐minded philosophers have gone astray in imputing to Hart a semantic version of expressivism. Notwithstanding that Hart’s theory of law can aptly be characterized as expressivist, that characterization is appropriate only when expressivism is understood as an account of the pragmatics of legal statements rather than as an account of their semantics.

This paper poses a new challenge to control-based theories of moral responsibility. Control-based theories – as defended, for instance, by Aristotle and John Martin Fischer – hold that an agent is responsible for an action only if she acted voluntarily and knew what she was doing. However, this paper argues that there is a large class of cases of unreflective behavior of which the following is true: the persons involved did not have the kind of control required by control-based theories, (...) yet we intuitively take the persons involved to be morally responsible.

The problem of act individuation is a debate about the identity conditions of human acts. The fundamental question about act individuation is: how do we distinguish between actions? Three views of act individuation have dominated the literature. First, Donald Davidson and G.E.M. Anscombe have argued that a number of different descriptions refer to a single act. Second, Alvin Goldman and Jaegwon Kim have argued that each description designates a distinct act. Finally, Irving Thalberg and Judith Jarvis Thomson have averred that (...) some acts are sequences of causally related events, which include both a primitive bodily action and some of its effects. All of these accounts have assumed that a simple invariantist account of act individuation captures how ordinary people distinguish between acts. For my dissertation, I devised an experiment to test the action theorists' assumptions. My data show that people's intuitions seem to depend on the valence of the consequences of the action under consideration. So, an invariantist account is not possible. In light of the empirical results, I argue that if we seek a folk account of act individuation, then that account should be able to explain the variability that seems to be present in people's intuitions about different cases.

This paper traces the intellectual trajectories of the first stand-alone theories of action, understood as both axiologically neutral and quasi-scientific from a methodological point of view. I argue that the rise of action theory of this kind corresponds to a particular moment of dissatisfaction within Western thought, and as such, it tells us far more about the history of philosophy than the subject itself. I conclude by explaining why subsequent failures to provide an acceptable theory of action are not accidental. (...) On the contrary, such failures owe themselves probably to the fact that formulating a theory of action is neither propitious nor useful. Thus, the most valuable lesson we can learn from philosophical desires for a theory of action is that we should take co-action as the starting point in our normative investigations, rather than positing action simpliciter as a problem to solve. That is, we should move away from propounding a theory of action, and instead focus on a paradigm shift, whereby we move away from a representational, towards a co-actional, model of action.

In this paper I will introduce a practical explication for the notion of expertise. At first, I motivate this attempt by taking a look on recent debates which display great disagreement about whether and how to define expertise in the first place. After that I will introduce the methodology of practical explications in the spirit of Edward Craig’s Knowledge and the state of nature along with some conditions of adequacy taken from ordinary and scientific language. This eventually culminates in the (...) respective explication of expertise according to which this term essentially refers to a certain kind of service-relation. This is why expertise should be considered as a predominantly social kind. This article will end up with a discussion of advantages and prima facie plausible objections against my account of expertise. (shrink)

Much has been said about the logical difference between rules and principles, yet few authors have focused on the distinct logical connectives linking the normative conditions of both norms. I intend to demonstrate that principles, unlike rules, are norms whose antecedents are linguistically formulated in a generic fashion, and thus logically described as inclusive disjunctions. This core feature incorporates the relevance criteria of normative antecedents into the world of principles and also explains their aptitude to conflict with opposing norms, namely (...) that their consequents are fulfilled to varying extents more frequently than those of rules. I conclude that the property of genericity should be predicated to the norm antecedent of principles, more precisely to the hypothetical action. This is of paramount importance to explain, in terms of logical implication and exclusion, the expansibility of competing principles, in contrast with the exclusive character of conflicting rules.

Speech and thought about what the law is commonly function in practical ways, to guide or assess behavior. These functions have often been seen as problematic for legal positivism in the tradition of H.L.A. Hart. One recent response is to advance an expressivist analysis of legal statements (Toh), which faces its own, familiar problems. This paper advances a rival, positivist-friendly account of legal statements which we call “quasi-expressivist”, explicitly modeled after Finlay’s metaethical theory of moral statements. This consists in a (...) descriptivist, “rule-relational” semantics combined with a pragmatic account of the expressive and practical functions of legal discourse. We argue that this approach is at least as well-equipped as expressivism to explain the motivational and prescriptive features of “internal” legal statements, as well as a fundamental kind of legal disagreement, while being better positioned to account for various “external” uses of the same language. We develop this theory in a Hartian framework, and in the final part of the paper argue (particularly against Toh’s expressivist interpretation) that Hart’s own views in The Concept of Law are best reconstructed along such quasi-expressivist lines.

This paper builds on a previous discussion of Stephen Mumford’s rejection of what he takes to be David Best’s argument for a distinction between purposive and aesthetic sports. That discussion concluded that Mumford’s argument misses its target, but closed by introducing a possible alternative argument, not made by Mumford, that might be thought to have the potential to secure Mumford’s conclusion. This paper considers that alternative argument, namely, the thought that the ascription of psychological predicates conceived of in terms of (...) defeasible criteria that constitute logically good evidence could preserve Best’s claim to be making a logical point while allowing a place for intention in relation to aims and purposes in sport. It is argued that the relationship between rules and intention is such that this alternative argument cannot secure Mumford’s conclusion. (shrink)

In Law's Empire Prof. Ronald Dworkin has advanced a new theory of law, complex and intriguing. He calls it law as integrity. But in some ways the more radical and surprising claim he makes is that not only were previous legal philosophers mistaken about the nature of law, they were also mistaken about the nature of the philosophy of law or jurisprudence. Perhaps it is possible to summarize his main contentions on the nature of jurisprudence in three theses: First, jurisprudence (...) is interpretive: “General theories of law… aim to interpret the main point and structure of legal practice”. Second, legal philosophy cannot be a semantic account of the word “law.” Legal philosophers “cannot produce useful semantic theories of law”. Third, legal philosophy or jurisprudence “is the general part of adjudication, silent prologue to any decision at law”. (shrink)

This paper discusses the first incarnation of what came to be known as the “Frege-Geach” point. The point was made by Peter Geach in his 1960 essay “Ascriptivism”, and developed in “Assertion”, a 1965 piece. Geach’s articles launch a wholesale attack on theories of non-descriptive performances advanced by “some Oxford philosophers” whom he accuses of ignoring “the distinction between calling a thing ‘P’ and predicating ‘P’ of a thing”. One view that Geach specifically targets is H. L. A. Hart’s claim (...) that sentences of the form “X φ-ed” are not primarily descriptive but ascriptive of responsibility for actions. Hart explicitly accepted Geach’s criticism, and disowned his essay. I argue that he was wrong to do so. Perhaps the essay was worth retracting, but not because of Geach’s objections. I begin by restating and refining Geach’s arguments, in order to bring out the flaw he claimed to have detected in the “pattern of philosophising” that he took Hart’s essay to exemplify. I go on to argue that Geach’s original point poses no obstacle either to non-descriptivism in general, or to Hart’s sui generis non-descriptivist claim in particular. (shrink)

In this article I argue for rule-based, non-monotonic theories of common law judicial reasoning and improve upon one such theory offered by Horty and Bench-Capon. The improvements reveal some of the interconnections between formal theories of judicial reasoning and traditional issues within jurisprudence regarding the notions of the ratio decidendi and obiter dicta. Though I do not purport to resolve the long-standing jurisprudential issues here, it is beneficial for theorists both of legal philosophy and formalizing legal reasoning to see where (...) the two projects interact.

Suppose two persons disagree over whether an act is right, justifying their judgments by appealing to divergent higher-level moral principles. These principles function as backing and rebuttals in their argumentation. To justify these principles, we may argue either that they would be accepted in some ideal model or that they are in reflective equilibrium with our considered moral judgments. Disagreement over the model indicates difference in philosophical anthropology but does not preclude resolution through argument.

In response to critique by Godden and Walton, this essay delineates the role of moral motivation in the commitment structure of ordinary presumptive inferences. It defends the capacity of ordinary presumptions to support discursive structures within which everyday argumentation can address defeasible claims and enable alignments and realignments in probative obligations, i.e., burdens of proof.

This paper discusses the parameters of an arguer's duties on the "dialectical tier of argument appraisal." Argumentative burdens incurred in making proposals will be compared with probative obligations which may be taken on in advising. The burdens t ypically incurred in these two kinds of illocutionary acts are strikingly different; accordingly, the arguer's obligation to response to objections would be circumscribed differently depending on which speech acts initiates the dialogue. This claim has i mplications for how we delimit a "good (...) case" for deliberative propositions. It also casts light on "manifest rationality" and the role of rhetorical art in argumentation.

It has often and correctly been remarked that the Hart-Fuller debate of 1956–1969 set the agenda for Anglo-American jurisprudence in the last half of the twentieth century. The nature of law, of legal obligation, of legal authority, and of law's relation to morality were the questions that debate made central to jurisprudence as we have since practiced it.

Like being able to drive a car, being autonomous is a socially attributed, claimed, and contested status. Normative debates about criteria for autonomy (and what autonomy entitles one to) are best understood, not as debates about what autonomy, at core, really is, but rather as debates about the relative merits of various possible packages of thresholds, entitlements, regulations, values, and institutions. Within different “regimes” of autonomy, different criteria for (degrees of) autonomy become authoritative. Neoliberal, solidaristic, and perfectionist regimes entail conflicting (...) understandings of what gets you autonomy and what autonomy gets you—for example, in relation to policies regarding physician-assisted suicide or financial support for senior citizens. In light of this, justifying a particular understanding of autonomy is inseparable from the task of arguing for the context-specific merits of a regime of autonomy as a whole and in relation to other ethical and political commitments.

The applicability of Bayesian conditionalization in setting one’s posterior probability for a proposition, α, is limited to cases where the value of a corresponding prior probability, PPRI(α|∧E), is available, where ∧E represents one’s complete body of evidence. In order to extend probability updating to cases where the prior probabilities needed for Bayesian conditionalization are unavailable, I introduce an inference schema, defeasible conditionalization, which allows one to update one’s personal probability in a proposition by conditioning on a proposition that represents a (...) proper subset of one’s complete body of evidence. While defeasible conditionalization has wider applicability than standard Bayesian conditionalization (since it may be used when the value of a relevant prior probability, PPRI(α|∧E), is unavailable), there are circumstances under which some instances of defeasible conditionalization are unreasonable. To address this difficulty, I outline the conditions under which instances of defeasible conditionalization are defeated. To conclude the article, I suggest that the prescriptions of direct inference and statistical induction can be encoded within the proposed system of probability updating, by the selection of intuitively reasonable prior probabilities.

The paper is a critical discussion of Sneddon’s recent proposal to revive ascriptivism in philosophy of action. Despite his declarations, Sneddon fails in his central task of giving an account of the distinction between actions and mre happenings. His failure is due to three major problems. First, the account is based on a misconceived methodology of “type” necessary and “token” sufficient conditions. Second, the “type” necessary condition he proposed is so weak that the connection that obtains between action and responsibility (...) also obtains between action and lack of responsibility. Third, neither the idea of responsibility nor the idea of defeating conditions is elucidated sufficiently to play any role in understanding what it is to be an action. (shrink)

Le concept de responsabilité vient généralement et spontanément à l'esprit de la plupart d'entre nous quand il est question d'action humaine. Il est surprenant pour cette raison que dans l'histoire de la philosophie de l'action, particulièrement l'histoire récente, la responsabilité ait été tenue autant à l'écart des discussions. En effet, après avoir joué chez les philosophes de la première génération suivant Wittgenstein, comme Hart, Melden, Chisholm et Rayfield, un rôle important, le concept de responsabilité a été, semble-t-il, progressivement évacué des (...) débats en philosophie analytique de l'action. Évidemment, l'action est encore affaire de responsabilité, puisque toute action peut être en principe sujette à une évaluation normative. Mais c'est le processus par lequel on en vient à évaluer la responsabilité d'une action qui ne semble plus faire partie des préoccupations des philosophes de l'action. Ceux-ci considèrent en général que de telles attributions devraient rester du resort de l'éthique ou du droit et n'ont rien à voir avec l'entreprise de la philosophie de l'action contemporaine qui, a bien des egards, se definit tout d'abord comme une extension de la philosophie de l'esprit.

En quoi les directives anticipées sont-elles normatives? En quoi ces écrits censés exprimer la volonté d’une personne à t1, devraient-ils être respectés par les soignants à t2?

There is an extensive body of philosophical, educational, and popular literature explaining Socratic pedagogy’s epistemological and educational ambitions. However, there is virtually no literature clarifying the relationship between Socratic method and doxastic responsibility. This article fills that gap in the literature by arguing that the Socratic method models many of the features of an ideally doxastically responsible agent. It ties a robust notion of doxastic responsibility to the Socratic method by showing how using defeaters to undermine participants’ knowledge claims can (...) facilitate responsible belief. It then argues that more robust notions of doxastic responsibility can be augmented by constructs found in the American Philosophical Association’s Delphi Report. Finally, it shows how considering challenges and modifying beliefs accordingly are objectives of the Socratic method and crucial elements of what it means to be a responsible believer. (shrink)

Realism has been a central object of attention among analytical philosophers for some decades. Starting from analytical philosophy, the return of realism has spread into other contemporary philosophical traditions and given birth to new trends in current discussions, as for example in the debates about “new realism.” Discussions about realism focused on linguistic meaning, epistemology, metaphysics, theory of action and ethics. The implications for politics of discussion about realism in action theory and in ethics, however, are not much discussed.

La philosophie analytique de l'action se réclame du langage ordinaire de l'action comme une des sources de ses data philosophiques.

The rule that a patient should give a free, fully-informed consent to any therapeutic intervention is traditionally thought to express merely a right of the patient against the physician, and a duty of the physician towards the patient. On this view, the patient may waive that right with impugnity, a fact sometimes expressed in the notion of a right not to know. This paper argues that the rule also expresses a duty of the patient towards the physician and a right (...) of the physician against the patient. The argument turns, first, on the truism that a physician has no obligation to commit a battery, or unauthorized touching, and, second, on the thesis that a patient necessarily cannot consent to something that is unknown to him. The conclusion is drawn that a patient is not free to receive treatment voluntarily without knowledgeably authorizing it. CiteULike Connotea Del.icio.us What's this? (shrink)

Abstract. The paper begins by challenging Hart's argument aimed to show that sanctions are not part of the concept of law. It shows that in the "minimal" legal system as understood by Hart, sanctions may be required for keeping the legal system efficacious. I then draw a methodological conclusion from this argument, which challenges the view of Hart (and his followers) that legal philosophy should aim at discovering some general, politically neutral, conceptual truths about law. Instead, the aim should be (...) to discover the values because of which certain things in the world are classified as law and others as non-law. Focusing on those would give us a more insight to the roles law plays in society, as well as more illuminating answers to traditional jurisprudential questions like the status of law in evil regimes.

The article considers two different interpretations of the reason model of precedent pioneered by John Horty. On a plausible interpretation of the reason model, past cases provide reasons to prioritize reasons favouring the same outcome as a past case over reasons favouring the opposing outcome. Here I consider the merits of this approach to the role of precedent in legal reasoning in comparison with a closely related view favoured by some legal theorists, according to which past cases provide reasons for (...) undercutting (or ‘excluding’) reasons favouring the opposing outcome. After embedding both accounts within a general default logic, I note some important differences between the two approaches that emerge as a result of plausible distinctions between rebutting and undercutting defeat in formal models of legal reasoning. These differences stem from the ‘preference independence’ of undercutting defeat. Undercutting reasons succeed in defeating opposing reasons irrespective of their relative strength. As a result, the two accounts differ in their account of the way in which precedents constrain judicial reasoning. I conclude by suggesting that the two approaches can be integrated within a single model, in which the distinction between undercutting and rebutting defeat is used to account for the distinction between strict and persuasive forms of precedential constraint.
