ABSTRACTIn ‘Freedom of the Will and the Concept of a Person,’ Harry Frankfurt argues that a successful analysis of the concept ‘human’ must reveal something that distinguishes humans from non-human...

The article proposes a new solution to the long-standing problem of the universality of essences in Spinoza's ontology. It argues that, according to Spinoza, particular things in nature possess unique essences, but that these essences coexist with more general, mind-dependent species-essences, constructed by finite minds on the basis of similarities that obtain among the properties of formally-real particulars. This account provides the best fit both with the textual evidence and with Spinoza's other metaphysical and epistemological commitments. The article offers new (...) readings of how Spinoza understands not just the nature of essence, but also the nature of being, reason, striving, definitions, and different kinds of knowledge.

Thirteen original essays by leading scholars explore aspects of Spinoza's ethical theory and, in doing so, deepen our understanding of it as the richly rewarding core of his system. They resolve interpretive difficulties, advance longstanding debates, and point the direction for future research.

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.
