Spinoza: Categorizations of Cognition

In this dissertation, I explore the distinction between reason (ratio) and intuitive knowledge (scientia intuitiva) in Spinoza’s Ethics in order to explain the superior affective power of the latter over the former. In addressing this fundamental but relatively unexplored issue in Spinoza scholarship, I suggest that these two kinds of adequate knowledge differ not only in terms of their method, but also with respect to their content. I hold that unlike reason, which is a universal knowledge, intuitive knowledge descends to (...) a level of particularity, including the adequate knowledge of one’s own essence as it follows directly from God, which is a superior form of self-knowledge. Since, for Spinoza, there is an intrinsic relationship between the pursuit of knowledge and how we live our lives, my interpretation of these two ways of knowing is that they are at the same time two ways of living.

While both intuitive knowledge and reason are adequate ways of knowing for Spinoza, they are not equal. Intuitive knowledge, which Spinoza describes as the ‘greatest virtue of mind’, is superior to reason. The nature of this superiority has been the subject of some controversy due to Spinoza's notoriously parsimonious treatment of the distinction between reason and intuitive knowledge in the Ethics. In this paper, I argue that intuitive knowledge differs from reason not only in terms of its method of cognition—but (...) also in terms of its content. More specifically, I maintain that there is something that is known by intuition, namely the unique essences of things, that is not known by reason. My argument is supported by an examination of Spinoza's account of essences in the Ethics, which reveals that he is committed to both unique and shared essences. Based on this dual commitment, I argue that whereas for Spinoza both reason and intuition can be said to reach adequate knowledge of the shared essence of a thing, the unique essence of a singular thing, which is nothing but its actual essence, can only be known through intuitive knowledge.
