This principle, and so characterised manifests itself in the SUM or I AM; which I shall hereafter indiscriminately express by the words spirit, self, and self-consciousness. In this, and in this alone, object and subject, being and knowing, are identical, each involving and supposing the other. In other words, it is a subject which becomes a subject by the act of constructing itself objectively to itself; but which never is an object except for itself, and only so far as by the very same act it becomes a subject. It may be described therefore as a perpetual self-duplication of one and the same power into object and subject, which presuppose each other, and can exist only as antitheses. SCHOLIUM. If a man be asked how he knows that he is? he can only answer, sum quia sum. But if (the absoluteness of this certainty having been admitted) he be again asked, how he, the individual person, came to be, then in relation to the ground of his existence, not to the ground of his knowledge of that existence, he might reply, sum quia Deus est, or still more philosophically, sum quia in Deo sum. But if we elevate our conception to the absolute self, the great eternal I AM, then the principle of being, and of knowledge, of idea, and of reality; the ground of existence, and the ground of the knowledge of existence, are absolutely identical, Sum quia sum [53]; I am, because I affirm myself to be; I affirm myself to be, because I am. THESIS VII If then I know myself only through myself, it is contradictory to require any other predicate of self, but that of self-consciousness. Only in the self-consciousness of a spirit is there the required identity of object and of representation; for herein consists the essence of a spirit, that it is self-representative. If therefore this be the one only immediate truth, in the certainty of which the reality of our collective knowledge is grounded, it must follow that the spirit in all the objects which it views, views only itself. If this could be proved, the immediate reality of all intuitive knowledge would be assured. It has been shown, that a spirit is that, which is its own object, yet not originally an object, but an absolute subject for which all, itself included, may become an object. It must therefore be an ACT; for every object is, as an object, dead, fixed, incapable in itself of any action, and necessarily finite. Again the spirit (originally the identity of object and subject) must in some sense dissolve this identity, in order to be conscious of it; fit alter et idem. But this implies an act, and it follows therefore that intelligence or self-consciousness is impossible, except by and in a will. The self-conscious spirit therefore is a will; and freedom must be assumed as a ground of philosophy, and can never be deduced from it. THESIS VIII
