4. But as there are two things (duo quædam), the mind and the love of it, when it loves itself; so there are two things, the mind and the knowledge of it, when it knows itself. Therefore the mind itself, and the love of it, and the knowledge of it, are three things (tria quædam), and these three are one; and when they are perfect they are equal. For if one loves himself less than as he is,—as for example, suppose that the mind of a man only loves itself as much as the body of a man ought to be loved, whereas the mind is more than the body,—then it is in fault, and its love is not perfect. Again, if it loves itself more than as it is,—as if, for instance, it loves itself as much as God is to be loved, whereas the mind is incomparably less than God,—here also it is exceedingly in fault, and its love of self is not perfect. But it is in fault more perversely and wrongly still, when it loves the body as much as God is to be loved. Also, if knowledge is less than that thing which is known, and which can be fully known, then knowledge is not perfect; but if it is greater, then the nature which knows is above that which is known, as the knowledge of the body is greater than the body itself, which is known by that knowledge. For knowledge is a kind of life in the reason of the knower, but the body is not life; and any life is greater than any body, not in bulk, but in power. But when the mind knows itself, its own knowledge does not rise above itself, because itself knows, and itself is known. When, therefore, it knows itself entirely, and no other thing with itself, then its knowledge is equal to itself; because its knowledge is not from another nature, since it knows itself. And when it perceives itself entirely, and nothing more, then it is neither less nor greater. We said therefore rightly, that these three things, [mind, love, and knowledge], when they are perfect, are by consequence equal.
