The Common Logic covers only the matters which come before us here as a portion of the third part of the whole system, together with the so-called Laws of Thought, which we have already met; and in the Applied Logic it adds a little about cognition. This is combined with psychological, metaphysical, and all sorts of empirical materials, which were introduced because, when all was done, those forms of thought could not be made to do all that was required of them. But with these additions the science lost its unity of aim. Then there was a further circumstance against the Common Logic. Those forms, which at least do belong to the proper domain of Logic, are supposed to be categories of conscious thought only, of thought too in the character of understanding, not of reason. The preceding logical categories, those viz. of Being and Essence, are, it is true, no mere logical modes or entities: they are proved to be notions in their transition or their dialectical element, and in their return into themselves and totality. But they are only in a modified form notions (cp. §§ 84 and 112), notions rudimentary, or, what is the same thing, notions for us. The antithetical term into which each category passes, or in which it shines, so producing correlation, is not characterised as a particular. The third, in which they return to unity, is not characterised as a subject or an individual: nor is there any explicit statement that the category: is identical in its antithesis,--in other words, its freedom is not expressly stated: and all this because the category is not universality.--What generally passes current under the name of a notion is a mode of understanding, or, even, a mere general representation, and therefore, in short, a finite mode of thought (cp. § 62). The Logic of the Notion is usually treated as a science of form only, and understood to deal with the form of notion, judgment, and syllogism as form, without in the least touching the question whether anything is true. The answer to that question is supposed to depend on the content only. If the logical forms of the notion were really dead and inert receptacles of conceptions and thoughts, careless of what they contained, knowledge about them would be an idle curiosity which the truth might dispense with. On the contrary they really are, as forms of the notion, the vital spirit of the actual world. That only is true of the actual which is true in virtue of these forms, through them and in them. As yet, however, the truth of these forms has never been considered or examined on their own account any more than their necessary interconnexion. A.--THE SUBJECTIVE NOTION.
