In the "Ethics",Spinoza discusses his beliefs about what he considers to be the three kinds of knowledge that come with perceptions. The first kind of knowledge he writes about is the knowledge of experiences. More precisely, this first type of knowledge can be known as the knowledge of things that could be "mutilated, confused, and without order."Spinoza’s second knowledge involves reasoning plus emotions.Spinoza defines the third and final knowledge as the knowledge of God, which requires rationality and reason of the mind. In more detail, Spinoza uses this type of knowledge to join together the essence of God with the individual essence.
I. By that which is self-caused, I mean that of which the essence involves existence, or that of which the nature is only conceivable as existent.II. A thing is called finite after its kind, when it can be limited by another thing of the same nature; for instance, a body is called finite because we always conceive another greater body. So, also, a thought is limited by another thought, but a body is not limited by thought, nor a thought by body.
