Accordingly, Metaphysics and Logic tend to form one body. For the distant and transcendent Absolute, which was the object of older Metaphysics, was substituted an Absolute, self-revealing in the terms of thought. Being is deposed from its absoluteness, and made the first postulate of thought. Former Metaphysics had dashed itself in vain against the reefs that girdle the island of the supersensible and noümenal, the supposed world of true Being: and the struggle at last grew so disastrous that Kant gave the signal to retreat, and to leave the world of true Being, the impregnable Thing-in-itself, to its repose. His advice to metaphysicians[4] was that, while scientific research continued to concentrate the attack of analysis upon single experiences conforming to certain conditions, they should investigate these' conditions of possible experience or foundations of objectivity. In other words, he turned observation to what he called Transcendental Logic. It was by means of this suggestion, understood in the widest sense, that Hegel was led to treat Logic as the science of ultimate reality. He had to show how these conditions when carried out in full gave the Unconditioned. He attacked the Absolute, if we may say so, in detail. The Absolute, as the totality, universe or system of Relativity, lays itself open to observation by deposing itself to a Relative. It possesses the differentiating power of separating itself as an object in passivity, from itself as a subject in action,--of deposing itself to appearance, of being _for_ itself, and also _in_ and _for_ itself. And thus Thought is the active universal,--which actualises itself more and more out of abstraction into concreteness. Hegel, then, solved the problem of Metaphysics by turning it into Logic. The same principle, Thought, appeared in both: in the former as a fixed and passive result, showing no traces of spontaneity,--in the latter as an activity, with a mere power of passing from object to object, discovering and establishing connexions and relations. The two sciences were fragments, unintelligible and untenable, when taken in abstract isolation. This is the justification, if justification be required, for Hegel's unification of Logic and Metaphysics. The Hegelian Logic falls into three parts: the theory of Transitory Being: the theory of Relative Being: and the theory of the Notion. The first and second of these in his Science of Logic are called Objective Logic; they also might be described as Metaphysics. The third part is more strictly on Logical ground. Or perhaps it is best to describe the whole as the Metaphysics of Logic.
