The idea of the mind, I repeat, and the mind itself are in God by the same necessity and follow from him from the same power of thinking.

Strictly speaking, the idea of the mind, that is, the idea of an idea, is nothing but the distinctive quality (forma) of the idea in so far as it is conceived as a mode of thought without reference to the object; if a man knows anything, he, by that very fact, knows that he knows it, and at the same time knows that he knows that he knows it, and so on to infinity.

But I will treat of this hereafter.
PROP.XXII.

The human mind perceives not only the modifications of the body, but also the ideas of such modifications.
Proof .-- The ideas of the ideas of modifications follow in God in the same manner, and are referred to God in the same manner, as the ideas of the said modifications.

This is proved in the same way as II.xx.
