 What is responsible for this singular place of intuition? Commentators are divided. Some (e.g. Soyarslan 2016) propose that it allows us to know truths that reason doesn’t. Others (e.g. Nadler 2003) think intuition is superior to reason as an epistemic method alone. This latter interpretation is a natural way to understand Spinoza’s own mathematical illustration of the ways all kinds of cognition, from imagination to intuition, can achieve the same correct result (E2p40s2). Likewise, as many of Spinoza’s predecessors have also held, intuition is an immediate knowledge, an insight “in one glance” (E2p40s2) into essences. The principal superiority of intuition seems to stem from the fact that it is in the business of cognizing essences directly, without the mediation of ideas of mere properties of things, whether “common” properties or other “adequate ideas of properties”, which form, as we have seen, the foundations of reason (3.2.3).
