Among the more notorious of Cartesian doctrines is the bête machine doctrine – the view that brute animals lack not only reason, but any form of consciousness (having no mind or soul). Recent English commentaries have served to obscure, rather than to clarify, the historical Descartes' views. Standard interpretations have it that insofar as Descartes intends to establish the bête machine doctrine his arguments are palpably flawed. One camp of interpreters thus disputes that he even holds the doctrine. As I (...) shall attempt to show, not only does Descartes affirm the doctrine, his supporting arguments are not palpably flawed – even if they ultimately come up short. It will indeed emerge that, in making his case, Descartes employs interesting argumentative strategies that have not been duly appreciated. (shrink)

While it is widely agreed that the infliction upon innocents of needless pain is immoral, many have argued that, even though nonhuman animals act as if they feel pain, there is no reason to think that they actually suffer painful experiences. And if our actions only appear to cause nonhuman animals pain, then such actions are not immoral. On the basis of the claim that certain behavioural responses to organismic harm are maladaptive, whereas the ability to feel pain is itself (...) adaptive, this article argues that the experience of pain should be viewed as the proximate cause of such occasionally maladaptive behaviour. But as nonhuman animals also display such maladaptive traits, we have reason to conclude that they feel pain. Hence, we have reason to hold that it is indeed possible to inflict needless pain on nonhuman animals, which would be immoral. (shrink)

In contrast to rigid conceptions of nonhuman animals, several philosophers have put forth ideas that suggest a more flexible and extended vision of other animals. In articulating the condition of humans in the world, philosophers have referenced ideas that necessarily bring other beings in common with humanity. Significantly, conceptions of movement and biological transformation have played a central role in these ruminations, thereby suggesting the importance of geographical variables in human/nonhuman relations. By drawing out the connections between these perspectives, this (...) paper outlines an ethics of extension. (shrink)

O artigo propõe, a partir de uma análise da célebre tese das “bestas-máquinas” de Descartes, uma discussão acerca da possibilidade de os animais, segundo esta doutrina, possuírem sensações, sendo assim capazes ou não de sentir dor; de sua recepção nos círculos científicos ingleses do século XVII em vista das práticas de vivissecção a sangue frio, correntes à época; de como os processos de mecanomorfose do pensamento afetam atualmente a vida dos animais.

RésuméCet article explore les liens entre le recours à la véracité de Dieu et les notions de certitude «métaphysique» et «morale» chez Descartes. Pour cela, je montre le rôle qu'elles jouent dans sa preuve de l'existence du monde extérieur, sa position sur l'existence d'autres esprits et celle sur l'«animal-machine». Descartes se sert de la véracité de Dieu dans le premier cas, maispas dans le deuxième ni le troisième. Je suggere que c'est parce que faire à nouveau appel à la véracité (...) de Dieu dans le cas des autres esprits aurait mis en péril sa doctrine de l'animal-machine. Je conclus en me penchant sur des passages de Descartes qui pourraient sembler incompatibles avec l'inter prétation que je fais du rôle important quejoue la certitude morale dans sa philosophic.
