opposition between subjectivity and objectivity which had not yet come up in Plato’s age. The independence of the “I” within itself and its explicit existence was foreign to him; man had not yet gone back within himself, had not yet set himself forth as explicit. The subject was indeed the individual as free, but as yet he knew himself only as in unity with his Being. The Athenian knew himself to be free, as such, just as the Roman citizen would, as _ingenuus_. But the fact that man is in and for himself free, in his essence and as man, free born, was known neither by Plato, Aristotle, Cicero, nor the Roman legislators, even though it is this conception alone which forms the source of law. In Christianity the individual, personal mind for the first time becomes of real, infinite and absolute value; God wills that all men shall be saved. It was in the Christian religion that the doctrine was advanced that all men are equal before God, because Christ has set them free with the freedom of Christianity. These principles make freedom independent of any such things as birth, standing or culture. The progress made through them is enormous, but they still come short of this, that to be free constitutes the very idea of man. The sense of this existent principle has been an active force for centuries and centuries, and an impelling power which has brought about the most tremendous revolutions; but the conception and the knowledge of the natural freedom of man is a knowledge of himself which is not old. B THE RELATION OF PHILOSOPHY TO OTHER DEPARTMENTS OF KNOWLEDGE. The History of Philosophy has to represent this science in that form of time and individualities from which its outward form has resulted. Such a representation has, however, to shut out from itself the external history of the time, and to take into account only the general character of the people and time, and likewise their circumstances as a whole. But as a matter of fact, the history of Philosophy does present this character, and that indeed in the highest possible degree; its connection with it is of the closest kind, and the particular appearance presented by a philosophy belonging to one special period, is only a particular aspect or element in the character. Because of this inward correspondence we have partly to consider more closely the particular relation borne by a philosophy to its historical surroundings, and partly, but pre-eminently, what is proper to itself, from which alone, after separating everything related however closely, we can fix our standpoint. This connection, which is not merely external but essential, has thus two sides, which we must consider. The first is the distinctly historical side, the second is the connection with other matters—the connection of Philosophy with Religion, for instance, by which we at once obtain a deeper conception of Philosophy itself. 1. THE HISTORICAL SIDE OF THIS CONNECTION.
