1 This proposition is comprehended much more clearly from 2 what we have said in the note to II. vii. We there showed that 3 the idea of body and body, that is, mind and body (II. xiii.), 4 are one and the same individual conceived now under the attribute 5 of thought, now under the attribute of extension; wherefore the 6 idea of the mind and the mind itself are one and the same thing, 7 which is conceived under one and the same attribute, namely, 8 thought. The idea of the mind, I repeat, and the mind itself are 9 in God by the same necessity and follow from him from the same 10 power of thinking. Strictly speaking, the idea of the mind, that 11 is, the idea of an idea, is nothing but the distinctive quality 12 (forma) of the idea in so far as it is conceived as a mode of 13 thought without reference to the object; if a man knows 14 anything, he, by that very fact, knows that he knows it, and at 15 the same time knows that he knows that he knows it, and so on to 16 infinity. But I will treat of this hereafter. 17 18
