Epistemic Argument For Distinction Between Essence and Existence
Feser gives three arguments for the distinction between essence and existence in the objects of our everyday experience (dogs, trees, planets, grass, humans, etc.) The first argument, the one examined in this post, is what I will call the Epistemic Argument (EA). It seems that we can grasp the essence of a tiger, a T-rex, and a centaur. We can know what each one is. Our grasping of these essences does not seem to include a grasp of the existence of any instance of them. In other words, we can know the essence of something without knowing whether it exists. Put differently, we can know what a thing most fundamentally is, without knowing that it exists. So, essence and existence are distinct. Put a bit more formally, here is the argument Feser provides: EA1. S can know that the essence of x is E without knowing that x exists EA2. Knowing that p without knowing that q, implies that p and q are distinct EA3. Hence, the essence of x is distinct from the existence of x A pro...
