Virtues are standardly understood as (1) essentially dispositions to perform certain actions and (2) having only instrumental value as motives to fulfill moral duties which can be fulfilled by persons lacking the virtue because the duties mandate only certain act-types. The argument of this article is that the duties of beneficence, gratitude and self-respect cannot be stated in terms of obligatory act-types because they cannot be fulfilled (except in deficient form) by persons lacking the appropriate virtue; they are, rather, duties (...) to cultivate specific virtues which therefore cannot themselves be defined in terms of obligatory actions.

Species egalitarianism is the view that all species have equal moral standing. To have moral standing is, at a minimum, to command respect, to be something more than a mere thing. Is there any reason to believe that all species have moral standing in even this most minimal sense? If so — that is, if all species command respect — is there any reason to believe they all command equal respect. The article summarises critical responses to Paul Taylor’s argument for (...) species egalitarianism, then explains why other species command our respect but also why they do not command equal respect. The intuition that we should have respect for nature is part of what motivates people to embrace species egalitarianism, but one need not be a species egalitarian to have respect for nature. The article closes by questioning whether species egalitarianism is even compatible with respect for nature. (shrink)

A central thesis of biocentrism is that all living things have intrinsic value. But when conflicts arise between the interests of humans and other organisms, this claim often has counterintuitive consequences. It would be wrong, for example, to swat pesky flies. Some biocentrists have responded by positing a taxonomy of interests in which human interests justifiably supersede those of other living things. I express doubts about whether this maneuver can succeed, and suggest that even if it does, it then commits (...) biocentrists to the claim that it is wrong not to harm living things, when doing so is necessary to advance nonbasic human interests, a position which runs counter to the biocentric attitude of respect for nature. As a result, biocentrists must adopt either a highly counterintuitive position or one that is contrary to their general outlook. I show that the introduction of the supererogatory may resolve not only this biocentric dilemma but other quandaries in environmental ethics. (shrink)
