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.

The “black page” in Spinoza’s Political Treatise has been much discussed and interpreted. These can be roughly divided into three groups: Approaches that see the “black page” as an extension of Spinoza’s theory of the passions and imagination; approaches that maintain that Spinoza excluded women from politics not because of their innate weaknesses but because of their social conditions; approaches that maintain that he excluded women because he saw them as weaker beings, but this contradicts his certain accounts, especially in (...) the Ethics. In this paper, I take the latter view. My contribution is to argue that this contradiction is not unique to the Ethics. I pursue my reading along two lines, one ontological and one political. In the first, I focus on the continuity between the Ethics and the Political Treatise and show that the “black page” is also inconsistent with the ontology and methodology of the Political Treatise itself. In the second, I argue that the exclusion of women also contradicts the concept of the political absolute developed in this last work, since this concept problematizes any kind of exclusion and provides for political stability the strategic principle of increasing the number of decision-makers as much as possible.
