Dans cet article, je présenterai la stratégie adoptée par J. B. Callicott pour ancrer l’écocentrisme dans les sciences biologiques et écologiques tout en restant en accord avec la méta-éthique humienne selon laquelle on ne peut directement inférer un jugement portant sur le devoir-être à partir d'un jugement portant sur l'être. Je le ferai en rappelant d’abord quelques caractéristiques importantes de la méta-éthique humienne quant à la relation entre la raison, les émotions et les jugements de valeur. Je montrerai ensuite comment cette méta-éthique, revisitée en relation avec l’explication évolutionnaire de l’éthique, permet de concevoir l’écocentrisme comme une évolution morale. Finalement, ces caractérisations méta-éthiques me permettront de montrer comment Callicott parvient à justifier la supériorité de l’écocentrisme sur les conceptions rivales en s'appuyant sur des considérations scientifiques, mais sans toutefois commettre le sophisme humien consistant à inférer directement des jugements portant sur le devoir-être à partir de jugements portant sur l'être.

Christopher Boorse’s Biostatistical Theory of Health has been the main contender among naturalistic accounts of health for the last 40 years. Yet, a recent criticism of this theory, presented by Elselijn Kingma, identifies a dilemma resulting from the BST’s conceptual linking of health and statistical typicality. Kingma argues that the BST either cannot accommodate the situation- specificity of many normal functions or cannot account for many situation-specific diseases. In this article, we expand upon with Daniel Hausman’s response to Kingma’s dilemma. We propose that recalling Boorse’s specification that health is an intrinsic property of its bearers and explicating this intrinsic property in relation to the concept of homeostasis can illuminate how proponents of naturalistic accounts of health should deal with the situation- specificity of normal functions. We argue that beyond what Boorse and Hausman have delineated, the situation- specificity of normal function cannot be fully captured in a simple dichotomy between normal and abnormal environment or between relevant and irrelevant situations. By bringing homeostasis to the fore of the analysis of health, we set out a richer picture of what the various situations that affect living organisms’ functional performance can be. Accordingly, we provide a broader classification of these various situations which, we contend, better accounts for the main intuitions that philosophers of medicine have sought to accommodate than previous naturalistic theories of health.

One aspect of J. Baird Callicott’s foundational project for ecocentrism consists in explaining how moral consideration for ecological wholes can be grounded in moral sentiments. Some critics of Callicott have objected that moral consideration for ecological wholes is impossible under a sentimentalist conception of ethics because, on both Hume and Smith’s views, sympathy is our main moral sentiment and it cannot be elicited by holistic entities. This conclusion is premature. The relevant question is not whether such moral consideration is compatible with the moral psychologies elaborated by Hume and Smith themselves, but, rather, whether it is possible given the moral psychology human beings actually possess. To answer this question, we must turn to empirical moral psychology and consider the possibility of a sentimentalist ecocentrism based on the community, autonomy, diversity model, a very promising model of human moral psychology developed by psychologists Richard Shweder, Paul Rozin, and Jonathan Haidt. This model can be used to assess the possibility of grounding ecocentrism in human moral sentiments. In light of this assessment, ecocentrism should be understood as a new form of naturalistic ethics informed by the moral emotions of disgust, shame, awe, and wonder.
