Spinoza is in a potentially untenable position. On the one hand, he argues that those who claim to see harmony in the universe are badly mistaken; they are falsely imagining rather than properly reasoning. On the other hand, harmony is positively discussed in his ethical writings and even serves as the basis for his vision of society. How can both be maintained? In this chapter l argue that this prima facie conflict between the two treatments of harmony is resolvable, but (...) that in resolving it, a new set of questions for Spinoza is raised. In doing so, I explore how harmony was used in the sixteenth through eighteenth centuries, which will help us better situate Spinoza. In doing so, we can recognize new possibilities and new connections between Spinoza and philosophers who are not often discussed in connection with him. (shrink)

Although Spinoza disagrees with Descartes's claim that animals are mindless, he holds that we may nevertheless treat them as we please because their natures are different from human nature. Margaret Wilson has questioned the validity of Spinoza's argument, since it is not clear why differences in nature should imply differences in ethical status. In this paper, I propose a new interpretation of Spinoza's argument that responds to Wilson's challenge. We have ethical commitments to other humans only because we share the (...) same nature, for this implies that in helping them become more perfect, we also make them more useful to us. However, since animals have different natures than we do, helping them perfect themselves may make them less useful to us. Reason dictates only what it can dictate unconditionally, so it does not guide us to pursue the good of lower animals. Though Spinoza's argument is valid, there is little reason to think it sound; I conclude with a brief criticism of Spinoza's doctrine of human nature, which plays a central role in the argument.
