In the preface to the Phenomenology of Mind Hegel makes an assertion which serves as a clue to his theory of substance: "everything depends on grasping and expressing the ultimate truth not as Substance but as Subject as well." ¹ While the concepts of ultimate truth, substance, subject are not translucent enough to permit an easy interpretation of the Hegelian intention, it is, nevertheless, clear that the Hegelian enterprise, for Hegel at least, is inextricably bound up with a move from a mere philosophy of substance to a philosophy of the subject, provided that subject is understood not in its logical sense, but in its metaphysical sense, meaning thereby a self or mind.
