These tropes thus form an effective weapon against the philosophy of the ordinary understanding, and the Sceptics directed them with great acuteness, sometimes against the common acceptation of things, and sometimes against principles of philosophic reflection. These sceptical tropes, in fact, concern that which is called a dogmatic philosophy—not in the sense of its having a positive content, but as asserting something determinate as the absolute; and in accordance with its nature, such a philosophy must display itself in all these forms. To the Sceptics, the Notion of dogmatic philosophy is in effect that something is asserted as the implicit; it is thus opposed to idealism by the fact of its maintaining that an existence is the absolute. But there is a misunderstanding or a formal understanding in considering that all philosophy that is not Scepticism is Dogmatism. Dogmatism, as the Sceptics quite correctly describe it, consists in the assertion that something determinate, such as ‘I’ or ‘Being,’ ‘Thought’ or ‘Sensation,’ is the truth. In the talk about idealism, to which dogmatism has been opposed, just as many mistakes have been made, and misunderstandings taken place. To the criticism which knows no implicit, nothing absolute, all knowledge of implicit existence as such is held to be dogmatism, while it is the most wanton dogmatism of all, because it maintains that the ‘I,’ the unity of self-consciousness, is opposed to Being, is in and for itself, and that the implicit in the outside world is likewise so, and therefore that the two absolutely cannot come together. By idealism that is likewise held to be dogmatism in which, as is the case in Plato and Spinoza, the absolute has been made the unity of self-consciousness and existence, and not self-consciousness opposed to existence. Speculative philosophy thus, indeed, asserts, but does not assert a determinate; or it cannot express its truth in the simple form of a proposition, although Philosophy is often falsely understood as pre-supposing an original principle from which all others are to be deduced. But though its principle can be given the form of a proposition, to the Idea what pertains to the proposition as such is not essential, and the content is of such a nature that it really abrogates this immediate existence, as we find with the Academicians. As a matter of fact, that which is now called a proposition, absolutely requires a mediation or a ground; for it is an immediate determinate that has another proposition in opposition to it, which last is again of a similar nature, and so on into infinitude. Consequently, each, as being a proposition, is the union of two moments between which there is an inherent difference, and whose union has to be mediated. Now dogmatic philosophy, which has this way of representing one principle in a determinate proposition as a fundamental principle, believes that it is therefore universal, and that the other is in subordination to it.
