After Neo-Platonism and all that is associated with it is left behind, it is not until Descartes is arrived at that we really enter upon a philosophy which is, properly speaking, independent, which knows that it comes forth from reason as independent, and that self-consciousness is an essential moment in the truth. Philosophy in its own proper soil separates itself entirely from the philosophizing theology, in accordance with its principle, and places it on quite another side. Here, we may say, we are at home, and like the mariner after a long voyage in a tempestuous sea, we may now hail the sight of land; with Descartes the culture of modern times, the thought of modern Philosophy, really begins to appear, after a long and tedious journey on the way which has led so far. It is specially characteristic of the German that the more servile he on the one hand is, the more uncontrolled is he on the other; restraint and want of restraint—originality, is the angel of darkness that buffets us. In this new period the universal principle by means of which everything in the world is regulated, is the thought that proceeds from itself; it is a certain inwardness, which is above all evidenced in respect to Christianity, and which is the Protestant principle in accordance with which thought has come to the consciousness of the world at large as that to which every man has a claim. Thus because the independently existent thought, this culminating point of inwardness, is now set forth and firmly grasped as such, the dead externality of authority is set aside and regarded as out of place. It is only through my own free thought within that thought can however be recognized and ratified by me. This likewise signifies that such free thought is the universal business of the world and of individuals; it is indeed the duty of every man, since everything is based upon it; thus what claims to rank as established in the world man must scrutinize in his own thoughts. Philosophy is thus become a matter of universal interest, and one respecting which each can judge for himself; for everyone is a thinker from the beginning.
