Primeiramente, oferecemos uma apresentação teórica da representação do pensamento prático, começando pela distinção entre silogismo dialético e silogismo demonstrativo. Fazemos referência à crítica de Toulmin contra o dedutivismo dominante de seu tempo. Em seguida, fornecemos argumentos para apoiar a relevância heurística do modelo de Toulmin para entender a discussão sobre a inclusão da lógica padrão na representação do pensamento comum. Afirmamos que o projeto analítico toulmaniano permite entender, com clareza metódica, a derrotabilidade dos argumentos do senso comum por meio da (...) investigação da noção modal de probabilidade na linguagem comum. First, we offer theoretical resemblance of the representation of practical reasoning, beginning with the distinction between demonstrative and dialectical syllogism. We make reference to the Toulmin’s critique against to the dominant deductivism in his time. Then we give arguments to sustain the heuristic relevance of Toulmin’s model to understand the discussion about the inclusion of default logics in the representation of ordinary reasoning. We assert that the Toulminian analytic design allows to understand, with methodical clarity, the defeasibility of common sense arguments by means of the investigation of the modal notion of probability in ordinary language.

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? Pour répondre, nous analysons les directives anticipées pour la fin de vie comme un acte de langage. Nous proposons d’y voir une ascription, au sens où H. L. A Hart a forgé le concept d’ ascription de responsabilité et de droits. Il se pourrait qu’une telle analyse aide à sortir de l’ornière du dilemme (...) entre paternalisme et autonomisme, et à contourner les questions métaphysiques sur l’identité personnelle. À la lumière des thèses de Hart et de ses principales critiques, nous considérons l’ascription d’un droit du patient, l’ascription de sa volonté et l’ascription des responsabilités pour l’acte effectué par les soignants d’après les directives.

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 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 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.

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.

Even given agreement on the totality of conditions that brought about an effect, there often is disagreement about the cause of the effect, for example, the disagreement about the cause of the Gulf oil spill. Different conditions’ being deemed responsible accounts for such disagreements. The defense of the act of deeming a condition responsible often depends on showing that the condition was the appropriate target of interference in order to have avoided the effect.

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.

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.
