 But this is just to say that, ultimately, we strive for a knowledge of God. The concept of any body involves the concept of extension; and the concept of any idea or mind involves the concept of thought. But thought and extension just are God’s attributes. So the proper and adequate conception of any body or mind necessarily involves the concept or knowledge of God. “The third kind of knowledge proceeds from an adequate idea of certain attributes of God to an adequate knowledge of the essence of things, and the more we understand things in this way, the more we understand God” (Vp25d). Knowledge of God is, thus, the mind’s greatest good and its greatest virtue.
