In defining those proofs as the grasping in thought of what we have called the elevation of the soul to God, we declared that in criticism we must directly reach an affirmative content.
And so, too, our treatment of the subject is not to be historical. Since time will not permit of me doing otherwise, I must partly refer you to histories of philosophy for the literary portion of the subject, and, indeed, the range of the historical element in these proofs may be held to be of the greatest possible extent, to be universal in fact, since every philosophy has a close connection with the primary question or with subjects which are most intimately related to it.

Besides, the historical element in anything which is a substantial
