In Locke, the inconsistency is still in the theory. We saw in an earlier chapter that Locke says, on the one hand: “Since the mind, in all its thoughts and reasonings, hath no other immediate object but its own ideas, which it alone does or can contemplate, it is evident that our knowledge is only conversant about them.” And: “Knowledge is the perception of the agreement or disagreement of two ideas.” Nevertheless, he maintains that we have three kinds of knowledge of real existence: intuitive, of our own; demonstrative, of God’s; and sensitive, of things present to sense.
