Any account of intentional action has to deal with the problem of how such actions are individuated. Medieval accounts, however, crucially differ from contemporary ones in at least three respects: for medieval authors, individuation is not a matter of description, as it is according to contemporary, ‘Anscombian’ views; rather, it is a metaphysical matter. Medieval authors discuss intentional action on the basis of faculty psychology, whereas contemporary accounts are not committed to this kind of psychology. Connected to the use of (...) faculty psychology is the distinction between interior and exterior acts. Roughly, interior acts are mental as opposed to physical acts, whereas exterior acts are acts of physical powers, such as of moving one’s body. Of course, contemporary accounts are not committed to this distinction between two ontologically different kinds of acts. Rather, they might be committed to views consistent with physicalist approaches to the mind. The main interpretative task in this paper is to clarify how Scotus and Ockham explain moral intentional action in terms of the role and involvement of these kinds of acts respectively. I argue that Scotus’s account is close to contemporary, ‘Anscombian’ accounts, whereas Ockham’s account is incompatible with them. (shrink)

Drawing on the findings of neuroscience, this text proposes and defends the hypothesis that the various modalities of sensation share a generic form that the author, Austen Clark, calls feature-placing.

Dans son article de 1944, « The Semantic Conception of Truth and the Foundations of Semantics », Alfred Tarski réfère en propres termes à la notion médiévale de « suppositio materialis ». L’interprétation qu’il en suggère, cependant, est historiquement trompeuse et l’inexactitude historique se double, en l’occurrence, de ce que l’on peut tenir pour une malencontreuse erreur philosophique. Dans « “la neige est blanche” est vraie », Tarski voit l’expression « la neige est blanche » comme le nom d’une certaine (...) phrase, alors que les médiévaux y auraient vu plutôt une occurrence de cette phrase elle-même prise dans un usage spécial, la suppositio materialis. L’article montre en quoi les deux approches diffèrent et soutient que la théorie médiévale est philosophiquement préférable, en ce que : 1) elle est descriptivement plus adéquate en ce qui concerne le fonctionnement réel des langues naturelles ; 2) elle est plus appropriée même pour les langages construits qu’elle rend plus fonctionnels et plus intelligibles ; 3) elle repose sur l’identification d’un phénomène important dont la généralité échappe aux sémantiques d’inspiration tarskienne, celui de la dualité de principe entre l’extension d’un terme pris en lui-même et celle qu’il reçoit dans un contexte propositionnel donné.In his 1944 paper “The Semantic Conception of Truth and the Foundations of Semantics”, Alfred Tarski refers in so many words to the medieval idea of “suppositio materialis”. The interpretation he suggests for it, however, is historically misleading, and this historical inaccuracy yields in this case what can be taken to be an unfortunate philosophical mistake. In “ ‘snow is white’ is true ”, Tarski sees the phrase “snow is white” as the name of a certain sentence, while the medieval philosophers would have seen it rather as an occurrence of that very sentence, but taken in a special use, the suppositio materialis . The paper shows how these two approaches differ exactly and argues that the medieval theory is philosophically preferable in that it is descriptively more adequate with respect to natural languages, it is more appropriate even for artificial languages, which it renders both more effective and more intelligible, and it rests upon the identification of an important phenomenon, the generality of which is missed by the Tarskian type semantics, namely the duality of principle between the extension of a term in itself and the extension it receives within a given propositional context.
