Abstract

For Spinoza’s epistemology, an image is an idea that represents an external body as actually existent. This kind of knowledge is the only source of inadequate knowledge, falsity, and error. On the contrary, reason is adequate knowledge because it comprehends common notions, i.e, properties of different things. Intuition is also adequate knowledge because it conceives formal essences of singular things. The main example is the genetic definition of a sphere, an adequate knowledge form by the power of thinking of the mind, without regard to existing extramental spheres. From these differences, some scholars conclude that imagination is always negative and should not deal with reason and intuition. But this conclusion will ban Spinoza’s epistemology from having adequate knowledge of existing individuals, such as Moses and the Hebrew State. In front of this view, this paper defends three theses: firstly, that the difference between the three kinds of knowledge is of genus, not of degree. Secondly, that adequate knowledge for Spinoza is a generic knowledge, i.e., insofar as S knows P insofar S deduces the effects, consequences, or properties of P. Thirdly, that adequate knowledge can include imagination through the proper use of the geometric method. In this case, imagination offers data to reason and intuition for having adequate knowledge of singular things that actually existed.
