Whatever in its origin is objective, is likewise as such necessarily finite. Therefore, since the spirit is not originally an object, and as the subject exists in antithesis to an object, the spirit cannot originally be finite. But neither can it be a subject without becoming an object, and, as it is originally the identity of both, it can be conceived neither as infinite nor finite exclusively, but as the most original union of both. In the existence, in the reconciling, and the recurrence of this contradiction consists the process and mystery of production and life. THESIS IX This principium commune essendi et cognoscendi, as subsisting in a WILL, or primary ACT of self-duplication, is the mediate or indirect principle of every science; but it is the immediate and direct principle of the ultimate science alone, i.e. of transcendental philosophy alone. For it must be remembered, that all these Theses refer solely to one of the two Polar Sciences, namely, to that which commences with, and rigidly confines itself within, the subjective, leaving the objective (as far as it is exclusively objective) to natural philosophy, which is its opposite pole. In its very idea therefore as a systematic knowledge of our collective KNOWING, (scientia scientiae) it involves the necessity of some one highest principle of knowing, as at once the source and accompanying form in all particular acts of intellect and perception. This, it has been shown, can be found only in the act and evolution of self-consciousness. We are not investigating an absolute principium essendi; for then, I admit, many valid objections might be started against our theory; but an absolute principium cognoscendi. The result of both the sciences, or their equatorial point, would be the principle of a total and undivided philosophy, as, for prudential reasons, I have chosen to anticipate in the Scholium to Thesis VI and the note subjoined. In other words, philosophy would pass into religion, and religion become inclusive of philosophy. We begin with the I KNOW MYSELF, in order to end with the absolute I AM. We proceed from the SELF, in order to lose and find all self in GOD. THESIS X The transcendental philosopher does not inquire, what ultimate ground of our knowledge there may lie out of our knowing, but what is the last in our knowing itself, beyond which we cannot pass. The principle of our knowing is sought within the sphere of our knowing. It must be some thing therefore, which can itself be known. It is asserted only, that the act of self-consciousness is for us the source and principle of all our possible knowledge. Whether abstracted from us there exists any thing higher and beyond this primary self-knowing, which is for us the form of all our knowing must be decided by the result.
