Spinoza's theory of attributes

Abstract Any account of Spinoza's understanding of attribute must be able to satisfy his definition criterion; that is, it must coherently accommodate the elements involved in his definition of attribute as “what the intellect perceives of a substance as constituting its essence” (E1d4). But this is not enough. There are several available readings that satisfy this criterion and are mutually incompatible. To know what Spinoza means we must supplement his definition criterion with a criterion aiming at consistency with other principles in his system. With the definition and consistency criteria in the backdrop, the aim of this paper is to offer a critical overview of the current state of the debate on Spinoza's theory of attributes.
