Value, Time, and Existence: Debates in The Ethics of Killing Animals

In this article, I review The Ethics of Killing Animals, discussing its relevance in the contemporary debate and critiquing its authors' discussion of time. The book covers a multitude of topics, including value theory, identity, the replaceability argument, a Kantian deontological approach to animal rights, and the political rights of nonhuman animals. In particular, the work focuses on three debates: Whether or not happiness and suffering should be symmetrically or asymmetrically weighted in moral considerations; whether or not nonhuman animals conceive of themselves as existing through time; and whether or not existence may be legitimately compared with nonexistence.
