How natural is natural deduction?– Gentzen's system of natural deduction intends to fit logical rules to the effective mathematical reasoning in order to overcome the artificiality of deductions in axiomatic systems (¶ 2). In spite of this reform some of Gentzen's rules for natural deduction are criticised by psychologists and natural language philosophers for remaining unnatural. The criticism focuses on the principle of extensionality and on formalism of logic (¶ 3). After sketching the criticism relatively to the main rules, I (...) argue that the criteria of economy, simplicity, pertinence etc., on which the objections are based, transcend the strict domain of logic and apply to arguments in general (¶ 4). (¶ 5) deals with Frege's critique of the concept of naturalness as regards logic. It is shown that this concept means a regression into psychologism and is exposed to the same difficulties as are: relativity, lack of precision, the error of arguing from `is' to `ought' (the naturalistic fallacy). Despite of these, the concept of naturalness plays the role of a diffuse ideal which favours the construction of alternative deductive systems in contrast to the platonic conception of logic (¶ 6).

Die Zusammenhänge die zwischen G. Freges und R. H. Lotzes logischen Lehren bestehen, sind, wie die gemeinsame Beurteilung der Gebrauchssprache zeigt, noch tiefer als allgemein angenommen. Insbesondere die von Frege konzipierte logische Sprachkritik ist in drei Punkten von Lotze beeinflußt. Lotze fordert nämlich die strenge Trennung von Logik und Gebrauchssprache. Daneben spielt der Begriff des Logischeinfachen eine zentrale Rolle in seiner Logik. Schließlich unterscheidet er den objektiven Gedanken von seiner Färbung. The connexions that exist between the logical doctrines of G. (...) Frege and R. H. Lotze are, as shows their common treatment of natural language, deeper than is generally admitted. In particular, the logical criticism of language conceived by Frege is influenced in three points by Lotze. Firstly, Lotze postulates the strict separation of logic and natural language. Furthermore, the idea of logical simplicity plays an important role in his logic. Finally, he distinguishes objective thought from its tone. (shrink)

In der Wissenschaftslehre Bolzanos (1837) spielt der Begriff der Auslegung eine nicht unwesentliche Rolle. Seine Hauptfunktion besteht in der Explikation der logischen Elemente im Satz und in der Reduktion der sprachlichen Sätze auf das Grundmuster,,A hat b". Die Herausbildung und die Behandlung der Auslegungsproblematik bei Bolzano sind stark vom neuzeitlichen Gedankengut, aber auch von der mittelalterlichen Philosophie und Logik beeinflußt. Obwohl sein Auslegungsbegriff der logischen Tradition weitgehend verpflichtet bleibt, weist er doch andererseits tiefgehende Parallelen mit der von Frege und Wittgenstein (...) entwickelten Methode der logischen Analyse auf, sodaß Bolzano auch in diesem Punkt als ein Vorläufer der analytischen Philosophie gelten kann.

En 1869, le jeune Brentano (1838-1917) consacre une étude à Auguste Comte (1798-1857), dans laquelle il rend un vibrant hommage au fondateur du positivisme. La question de la métaphysique mise à part, l’étude fait apparaître des affinités profondes entre le positivisme comtien et la philosophie de Franz Brentano : chez les deux penseurs on rencontre en fait le même refus de séparer la philosophie de la science. Au-delà de ces affinités qui existent au départ, la lecture de Comte aura durablement (...) marqué la pensée de Brentano. Tout ceci explique pourquoi l’héritage de Brentano a pu jouer un rôle certain dans l’avènement du néo-positivisme dans la Vienne des premières décennies du XX e siècle. La position particulière que Brentano occupe aussi bien par rapport au positivisme ancien qu’au néo-positivisme soulève deux problèmes majeurs. Le premier a trait au rôle que Brentano a pu jouer dans la transmission de l’idéal positiviste. Le second, plus fondamental, se rapporte aux liens généralement sous-estimés qui existent entre le néo-positivisme et la philosophie positiviste de Comte. (shrink)

Sowohl in seiner Habilitationsschrift Das Wesen der Wahrheit nach der modernen Logik (1910) als auch in Allgemeine Erkenntnislehre (1918) setzt Moritz Schhck sich kritisch mit der Phänomenologie Husserls auseinander. Im Zentrum der Kritik steht neben dem Anschauungsbegriff die Hypostasierung der logischen Bedeutungen. Es läßt sich zeigen, daß die Auseinandersetzung mit Husserl eine wesentliche Rolle in der Herausbildung der lingualistischen Bedeutungstheorie Schlicks spielt.

Alfred Tarski a joué un rôle déterminant dans la déconstruction du clivage classique de l’analytique et du synthétique alors même que les ouvrages consacrés à ce chapitre de la philosophie restent, en général, relativement discrets au sujet de son rôle au profit de W. V. O. Quine. La critique de Tarski, qui s’articule dès 1930, s’organise le long de deux axes principaux. Le premier a trait à la difficulté de définir objectivement la notion de logicité ; le second, qui s’appuie (...) sur une conception holiste de la science, admet la possibilité d’une rectification des principes logiques au nom de l’expérience. Sur ce point, les objections ponctuelles de Tarski anticipent la critique plus systématique que Quine adressera à la notion de l’analyticité. L’analyse des principales étapes de la critique de Tarski révèle toutefois que sa pensée n’est pas toujours exempte de tensions internes. Alfred Tarski has played a decisive role in the refutation of the classic cleavage between analytic and synthetic truths, though the studies which deal with this chapter of philosophy generally stress the role of W. V. O. Quine in this question and omit to mention Tarski’s name. Tarski’s critique, which has been expressing itself since 1930, is developed along two main lines. The first concerns the difficulty of giving an objective definition of logical notions ; the second, based on a holistic conception of science, maintains the possibility of the refutation of logical principles by experience. In this question the selective objections of Tarski anticipate the more systematic critique of analyticity by Quine. However, the analysis of the different steps in Tarski’s critique shows that his way of thinking is not free of inner tensions. (shrink)

L’A. revient, dans le prolongement de son ouvrage L’anthropologie logique de Quine (qui plaçait l’accent sur la traduction, la logique et le principe de charité chez Quine) sur un élément souvent négligé de la thèse d’indétermination de la traduction, à savoir la reconstruction/identification des connecteurs logiques par l’assentiment et le dissentiment. Après avoir examiné diverses objections à l’utilisation par Quine des « fonctions de verdict » dans la traduction, l’A. en vient à la véritable motivation de Quine dans son recours (...) à l’assentiment, qui émerge dans l’ouvrage méconnu the roots of reference. Quine revient, par cet usage de l’assentiment, à la question de l’analyticité et à sa critique des « Deux dogmes », qu’il nuance, dans son oeuvre tardive, par la suggestion d’une analyticité non seulement naturalisée, mais socialisée.

This book tackles the question of why the brain is so difficult to fully understand. In neuroscience, data are acquired and analyzed with astonishing techniques and accumulate rapidly. Nevertheless, try to explain how a person can think or why there is such a condition as schizophrenia, and it appears that we really know little. To approach these difficulties, the authors first present a number of case studies in which the operation of a neural circuit is worked out in some detail (...) and, at the same time, the functional significance of the operation is also understood. These examples are complicated in their biologic specifics but are conceptually straightforward. The examples are hoped to provoke an appreciation for what neuroscience can accomplish. The authors then develop some thoughts on how these issues can be addressed----instead of considering cognition in general, taking instead a subset of cognition that does lend itself to formal description.

It is notoriously difficult to spell out the norms of inductive reasoning in a neat set of rules. I explore the idea that explanatory considerations are the key to sorting out the good inductive inferences from the bad. After defending the crucial explanatory virtue of stability, I apply this approach to a range of inductive inferences, puzzles, and principles such as the Raven and Grue problems, and the significance of varied data and random sampling.

In everyday parlance, "inhibition" suggests repression, tight control, the opposite of freedom. In medicine and psychotherapy the term is commonplace, its definition understood. Relating how inhibition—the word and the concept—became a bridge between society at large and the natural sciences of mind and brain, Smith constructs an engagingly original history of our view of ourselves. Not until the late nineteenth century did the term "inhibition" become common in English, connoting the dependency of reason and of civilization itself on the repression (...) of "the beast within." This usage followed a century of Enlightenment thought about human nature and the nature of the human mind. Smith traces theories of inhibitory control from the moralistic psychologies of the early nineteenth century to the famous twentieth-century schools of Sherrington, Pavlov, and Freud. He finds that the meanings of "inhibition" cross disciplinary boundaries and outline the growth of our belief in the self-regulated person. (shrink)

This is a three-part exchange on the relationship between belief and credence. It begins with an opening essay by Roger Clarke that argues for the claim that the notion of credence generalizes the notion of belief. Julia Staffel argues in her reply that we need to distinguish between mental states and models representing them, and that this helps us explain what it could mean that belief is a special case of credence. Roger Clarke's final essay reflects on the (...) compatibility of the previously discussed views with dualist and monist interpretations of our mental states and our ways of modeling them. (shrink)

Among other interesting proposals, Juan Comesaña’s _Being Rational and Being Right_ makes a challenging case that one’s evidence can include falsehoods. I explore some ways in which we might have to rethink the roles that evidence can play in inquiry if we accept this claim. It turns out that Comesaña’s position lends itself to the conclusion that while false evidence is possible and not even terribly uncommon, I can be rationally sure that I don’t currently have any and perhaps also (...) that I won’t get any, and (absent certain evidence to the contrary) you are not afflicted with any either. This conclusion might seem too good to be true. I finish by raising a puzzle about one of the main motivations for Comesaña’s view. (shrink)

Historians of the Victorian period have begun to re-evaluate the general background and impact of Darwin's theory of the origin of species by means of natural selection. An emerging picture suggests that the Darwinian theory of evolution was only one aspect of a more general change in intellectual positions. It is possible to summarize two correlated developments in the second half of the nineteenth century: the seculariszation of majors areas of thought, and the increasing breakdown of a common intellectual milieu. (...) Studies in linguistics, historical criticism, socio-political theory, theologys, and anthropology, besides evolutionary theory, contributed to these developments. It has also been argued that the background of evolutionary thought lay within a relatively unified early Victorian intellectual context with shared religious, moral, and scientific concepts. Evolutionary theory contributed to the disintegration of this shared context, but it did not intrinsically assume a clear demarcation between value-laden ideas and scientific ideas. On the one hand, in the later Victorian period, religious and scientific intellectuals found it increasingly hard to share common ground. On the other hand, they did sometimes share an enthusiasm for applying biological models to social and ethical theory. It is necessary to look closely before ascribing any increased differentiation of positions to the impact of evolutionary biology. (shrink)

Now that it has become so commonplace, we rarely blink an eye at camera footage framed by the crosshairs of a sniper’s gun or from the perspective of a descending smart bomb. But how did this weaponized gaze become the norm for depicting war, and how has it influenced public perceptions? _Through the Crosshairs _traces the genealogy of this weapon’s-eye view across a wide range of genres, including news reports, military public relations images, action movies, video games, and social media (...) posts. As he tracks how gun-camera footage has spilled from the battlefield onto the screens of everyday civilian life, Roger Stahl exposes how this raw video is carefully curated and edited to promote identification with military weaponry, rather than with the targeted victims. He reveals how the weaponized gaze is not only a powerful propagandistic frame, but also a prime site of struggle over the representation of state violence. (shrink)

It is possible to draw upon Marx’s thinking without emphasizing an automatic relationship between an economic ‘base’ and a political ‘superstructure’. The development of capitalism must then be understood as resulting from the ‘conceptual separation’ of the economic and political issues. However, the research that favours this approach fails to provide the tools for a precise and systematic study of the political work which makes this separation possible. For his part, through the development of field theory and the emphasis on (...) the notion of symbolic power, Pierre Bourdieu offers the means to analyse the political work of multiple agents, but he does not formulate a theory of capitalism tailored to his findings. It seems worthwhile to take up and extend some of his proposals to open up avenues of thought in this direction. It is then about considering that different fields coexist, each of which lends itself to a political struggle based on the assertion of symbolic power; each field contributes to a ‘conceptual separation’ of the economic and political issues, which is itself constitutive of capitalism. As a result, production and trade operations seem to be part of a natural and autonomous process. Capital can thus be accumulated without necessitating the direct use of force. The combination of fields can lend itself to certain variations. It always shapes the political structures of accumulation. (shrink)

School effectiveness research together with what is now described as the 'school improvement movement' has captured both the Conservative and New Labour imaginations as a basis for educational planning and policy making in the UK. Internationally school effectiveness enjoys and expanding and enthusiastic audience. This book provides a critique of this research genre, particularly in the light of the recent calls for teaching to go 'back to the basics'. The editors argue that this school effectiveness research is simplistic in its (...) analysis of educational problems. Far from getting to the bottom of the problem of failing students and schools, they argue, these 'movements' are merely scratching at the surface of the problems and coming up with notions for superficial improvements.

Can we lose our concepts? A case like ‘phlogiston’ invites a positive answer, though the sensefulness of ‘There is no phlogiston’ gives us pause. But concepts are about more than just ‘extension-determination’; hence Diamond’s examination of putative loss of moral concepts does point to a possible phenomenon. That loss of concepts could be regrettable seems to make room for the thought that having certain concepts could likewise be regrettable. Anscombe’s critique of the concept of ‘moral obligation’ appears to be suggesting (...) this, but it presents a dilemma: do the relevant words and phrases have a ‘special sense’ or are they senseless? Either answer is acceptable, I argue; roughly speaking, confused use makes for confused meaning. Objections coming from a certain picture of the autonomy of grammar fail. A diagnosis of ‘confused use’ can lead naturally to our seeing speakers as caught up in a species of dishonesty or inauthenticity, and also to our referring to the ‘kind of nonsense’ being talked. This last phrase seems to fall foul of the sort of consideration Diamond raised when discussing nonsense in the Tractatus. However, the case of ‘secondary sense’ shows us how we can understand this reference to ‘kinds of nonsense’. (shrink)

While it is impossible to transfigurephilosophical and Judaic thought of EmmanuelLevinas into a moral agenda for education orthe programmatic regularities of a pedagogicalmethodology, this paper argues for theimportance of his work for re-openingeducational questions. These questions engagethe problem of what it could mean to livehistorically, to live within an uprightattentiveness to traces of those who haveinhabited times and places other than one'sown. In this sense, I address the problem ofremembrance as a question of and for history,as a force of inhabitation, (...) as an inheritance weare obligated to live within, that intertwineswith our sense of limits and possibilities,hopes and fears, identities and distinctions.Substantively, this problem is manifest in howone attends to the experiences of others: howone reads, how one views, and how one listens,always historically specific normalizedpractices that in any given epoch are ingrainedin what it means to live in consort withothers, to live as though the lives of otherpeople mattered. The paper seeks to display thefecundity of the thought of Levinas forre-thinking such issues. (shrink)

. Prospects for uniting religion and science are brightened by recently changed views of consciousness and mind‐brain interaction. Mental, vital, and spiritual forces, long excluded and denounced by materialist philosophy, are reinstated in nonmystical form. A revised scientific cosmology emerges in which reductive materialist interpretations emphasizing causal control from below upward are replaced by revised concepts that emphasize the reciprocal control exerted by higher emergent forces from above downward. Scientific views of ourselves and the world and the kinds of values (...) upheld by scientific belief undergo basic transformations, making them more compatible with religious motivation and moral responsibility.
