 As to the fact that there can be nothing in the mind, in so far as it is a thinking thing, of which it is not aware [conscius], this seems to me to be self-evident. For there is nothing that we can understand to be in the mind, regarded in this way, that is not a thought or dependent on a thought. If it were not a thought or dependent on a thought it would not belong to the mind qua thinking thing; and we cannot have any thought of which we are not aware [conscius] at the very moment when it is in us. In view of this I do not doubt that the mind begins to think as soon as it is implanted in the body of an infant, and that it is immediately aware [conscius] of its thoughts, even though it does not remember this afterwards because the impressions of these thoughts do not remain in the memory. (CSM II 171–172 / AT VII 246)
