The negative mean to these one-sided principles is the Notion, which, abrogating fixed extremes of determination such as these, moves them and sets them free from a mere state of opposition. This movement of the Notion, the revival of dialectic—directed as it is against these one-sided principles of abstract thinking and sensation—we now see in its negative aspect, both in the New Academy and in the Sceptics. Even the Stoics, as having their principle in thought, cultivated dialectic, though theirs was (pp. 254, 255) a common logic, in which the form of simplicity passes for the Notion, while the Notion, as such, represents the negative element in it, and dissolves the determinations, which are taken up into that simplicity. There is a higher form of the Notion of dialectic reality, which not only applies itself to sensuous existence, but also to determinate Notions, and which brings to consciousness the opposition between thought and existence; not expressing the Universal as simple Idea, but as a universality in which all comes back into consciousness as an essential moment of existence. In Scepticism we now really have an abrogation of the two one-sided systems that we have hitherto dealt with; but this negative remains negative only, and is incapable of passing into an affirmative. C. THE NEW ACADEMY. As opposed to the Stoic and Epicurean Dogmatism, we first of all have the New Academy, which is a continuation of Plato’s Academy in as far as the followers of Plato are divided into the Old, Middle, and New Academies; some indeed allow of a fourth Academy and even a fifth.[168] The most noteworthy figures here are those of Arcesilaus and Carneades. The establishment of the Middle Academy is ascribed to Arcesilaus, and the New Academy is said to contain the philosophy of Carneades; but this distinction has no signification. Both of these are closely connected with Scepticism, and the Sceptics themselves have often trouble in distinguishing their standpoint from the Academic principle. Both have been claimed by Scepticism as Sceptics, but between the Academics and pure Scepticism a distinction has been drawn, which is certainly very formal, and has but little signification, but to which the Sceptics in their subtlety undoubtedly attached some meaning. The distinction often consists in the meanings of words only, and in quite external differences.
