Devant le constat du déclin toujours plus rapide de la diversité biologique et les limites des res- sources disponibles pour l’enrayer, il est nécessaire de déterminer quels moyens devraient être engagés dans sa protection. Pour ce faire, une méthode efficace serait d’évaluer les bénéfices tirés de la biodiversité afin d’estimer rationnellement les coûts légitimes de sa protection. L’évaluation économique, qui se présente d’emblée sur un mode quantitatif, serait alors un outil précieux. Dans ce texte, nous présentons différentes méthodes d’évaluation économique (...) de la biodiversité ainsi que certaines de leurs limites méthodologiques. Par la suite, nous montrons qu’en dépit de ses avantages pratiques, l’évaluation économique échoue à représenter l’ensemble des valeurs en jeu dans la protection de la biodiversité. Nous décrivons alors trois types de valeurs incommen- surables avec des bénéfices économiques : la valeur de legs, qui renvoie aux obligations de trans- mission du patrimoine naturel dont nous avons hérité ; la valeur d’existence, qui renvoie à la considération morale d’intérêts autres que ceux des êtres humains ; la valeur de transformation, qui renvoie à la capacité d’examiner et de critiquer nos préférences et inclinaisons afin d’inclure celles-ci dans une vision du monde rationnelle et cohérente. Pour conclure, nous plaidons en faveur de l’élaboration de méthodes de concertation et d’évaluation participatives et pluralistes permettant de rendre compte de la diversité et de l’hétérogénéité des valeurs de la biodiversité.

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

Gabriel Bonnot de Mably takes up the republican commonplace that the desire for esteem is what could motivate the fulfilment of duties of civic virtue. This commonplace, however, has become problematic through the discussion of the problem of human corruption in philosophers such as Blaise Pascal and Nicolas Malebranche. In this article, I will show that Mably takes this problem seriously. However, his critique of Malebranche’s solution to this problem and his critique of the economic reinterpretation of Malebranche’s concept (...) of natural order in the work of Le Mercier de la Rivière motivate his own republican defense of the moral value of the desire for esteem. What makes this defense plausible is his argument that distorted esteem derives from imagination that is distorted, not only as a result of natural factors, but in many cases rather as a result of misguided politics. If some cases of distorted esteem derive from misguided politics, Mably argues, then they can be modified by republican constitution building that modifies the imagination of citizens. (shrink)

In the 17th century the dissemination of philosophical ideas relied also on the critical summaries and reviews published by the journals. The focus of this paper is the reactions of two of these journals – the Journal de Trévoux, edited by the Jesuits of the Parisian Collège Louis Le Grand, and the Journal des Sçavans – to Condillac’s works. The Jesuit journal, under the direction of pére Berthier – probably himself the author of the reviews – had a precise plan (...) in presenting Condillac’s philosophy as an anti-empiricist and anti-materialist doctrine, sometime giving a misrepresentation of the author’s thought, which is also criticized on some points. The decision of the Journal de Trévoux to review the main works of Condillac is anyway worthy of attention, and probably betrays a certain interest toward the more up to date philosophical enquiry. The Journal des Sçavans was on the other hand more faithful in presenting Condillac’s works. (shrink)

This essay—part of a larger project of constructing a new, historically informed philosophy of dance, built on four phenomenological constructs that I call “Moves”—concerns the second Move, “gesture,” the etymology of which reveals its close connection to the Greek word “metaphor.” More specifically, I examine the treatments of gesture by the philosophers George Herbert Mead and Etienne Bonnot de Condillac, both of whom view it as the foundation of language. I conclude by showing how gesture can be used in (...) analyzing various types of dance, which in turn suggests transformational potential for philosophy, dance, and society as a whole. (shrink)

The present article proposes to study Condillac’s analysis of Spinoza’s Ethics, against the background of the more general criticism that the French abbot makes of the seventeenth-century logique de système. From the Essai sur l’origine des connaissances humaines to the Traité des systèmes to the later texts, Condillac’s theory and critique of systems are crossed by two components: on the one hand, the search for the sensory origin of ideas, that Condillac radicalizes in his Traité des sensations into a theory (...) of knowledge as a ‘transformed sensation’. On the other hand, an operative logic of signs, which from the Essai to the works subsequent to the Traité des sensations translates sensibility into a knowledge, or a ‘well-made language’, whose logic is calculation. My objective is to clarify how the new ‘systematic spirit’, repeatedly invoked by the abbot, departs from the ‘bad metaphysics’ that he claims to liquidate. The comparison with the Spinozist system will be illuminating: in his treatise on the metaphysical systems of the seventeenth century Condillac proposes a critical analysis of the ‘geometrical spirit’; in his latest work, La langue des calculs, he proposes a new logic to which he assigns the task of bringing together the abstract and the concrete, beyond the ruins of classical metaphysics. The ‘systematic spirit’ and ‘spirit of system’ will be revealed, in spite of Condillac’s efforts, as being much closer to what it appears at first sight. (shrink)

Cabanis’ enucleation of the notion of instinct in his Rapports du physique et du moral de l’homme articulates through a critique of the use of this notion by Étienne Bonnot de Condillac, who would not have recognised the founding role of physiology in human perceptive and intellectual activity. An analysis of Cabanis’ criticism to Condillac and an investigation of the meaning attributed to the notion of instinct by both philosophers allow to individuate in this notion the expression of two (...) different types of materialism. The different position of Cabanis and Condillac on this notion, in fact, reflects the divergence on a series of notions – e.g. reflexion, sensitivity, habitus – which can be traced back to the different aims of their investigations. In addition to highlighting this basic divergence, this paper aims to bring out – especially referring to Condillac’s Logique – some points of contact, of which Cabanis seems not to have considered, concerning the conception of the human body as ‘organisation physique’.
