The Logic of Hegel. The concrete concept or Idea.

Neglecting the particular differences between these thinkers and the genetic process by which we pass from one to the other, and taking the result of that speculative movement in its most mature form, which is the philosophy of Hegel, we see in it (like a new, securely established society after the frequent changes of a revolution) the establishment of the new doctrine of the concept. Kant's unconsciousness of the consequences of the a priori synthesis had been such that he had not hesitated to affirm that Logic, since the time of Aristotle, had possessed so just and secure a form as not to need to take one single step backward, and to be unable to take one forward.[15] But Hegel insisted that this was rather a sign that that science demanded complete re-elaboration, since an application of two thousand years should have endowed the spirit with a more lofty consciousness of its own thought and of its own essential nature.[16] What was the concept for Hegel? It was not that of the empirical sciences, which consists in a simple general representation and therefore always in something finite; it is barbaric to give the name concepts to intellectual formations, like "blue," "house," or "animal." Nor was it the mathematical concept, which is an arbitrary construction. All the logical rationality that there is in mathematics is what is called irrational. These so-called concepts are the products of the abstract intellect; the true concept is the product of the concrete intellect, or reason. It has therefore nothing to do with the immediate knowledge of the sentimentalists and of the mystics, and with the intuition of the æstheticists; such formulae as these express the necessity for the concept, but give only a negative determination of it. They assert what it is not in relation to the empirical sciences and then misstate what it is in philosophy. For the rest, the shortcomings of the abstract intellect, generating the pure void or thing in itself(which far from being, as Kant believed, unknowable, is indeed the best known thing of all, the abstraction from everything and from thought itself) prepare the environment for the phantasms and caprices of mysticism and intuitionism. The true concept is the idea, and the idea is the absolute unity of the concept and of its objectivity.

Identity of the Hegelian Idea with the Kantian a priori synthesis.

This definition has sometimes seemed whimsical, sometimes most obscure; yet it presents nothing but the elaboration in a more rigorous form of the Kantian a priori synthesis, so that these two terms could without further difficulty be regarded as equivalent; the a priori logical synthesis is the Idea and the Idea is the a priori logical synthesis. If Hegel has not been understood, that is due to the fact that Kant himself has not been understood. Those who assert that they understand what Kant meant to say, but not what Hegel meant to say, deceive themselves. For Kant and Hegel say the same thing, though the latter says it with greater consciousness and clearness, that is to say, better.[17]

The Idea and the Antinomies. The Dialectic.

The idea, the concrete universal, the pure concept, rebels against the mechanical divisions employed for the empirical concepts. For it has its own division, its own proper and intimate rhythm, by means of which it divides and unifies, and unifies itself when dividing and divides itself when unifying. The concept thinks reality, which is not immobile but in motion, not abstract being, but becoming; and therefore in it distinctions are generated one from another and oppositions reconciled. Hegel not only gives the true meaning of the Kantian a priori synthesis, recognizing it as the concrete concept, but replaces the antinomies in its bosom. The contradiction is not due to the limitation of thought before a non-contradictory reality, which thought is unable to attain; it is the character of reality itself, which contradicts itself in itself, and is opposition, coincidentia oppositorum, the synthesis of opposites, or dialectic. A new doctrine of opposites and the outlines of a new doctrine of distinction accompanies the new doctrine of the pure concept. In this philosophy is truly summarized all the previous history of thought. The concept of Socrates has acquired the reality of the idea of Plato, the concreteness of the substance of Aristotle, the unity-in-opposition of Cusanus and Bruno, the Vichian reconciliation of philosophy and philology, the unity-in-distinction of the Kantian synthesis and the æsthetic suppleness of Schelling's intellectual intuition.

The lacunæ and errors of the Hegelian Logic. Their consequences.

Nevertheless, the history of thought does not stop at Hegel. In Hegel himself are found the points to which later history must attach itself; the lacunæ which he left and the errors into which he fell. The fundamental error was the abuse of the dialectic method, which originated for the philosophic solution of the problem of opposites, but was extended by Hegel to the distinct concepts, so that he interpreted even the Kantian synthesis itself as nothing but the unity of opposites. Hence arises his incapacity to attribute their true value and function to the alogical forms of the spirit, such as art, and to the atheoretic, such as the natural sciences and mathematics; and even to logical thought itself, which, violating the laws of the synthesis, ended by imposing itself upon history and the natural sciences, attempting to resolve them into itself by dialectizing them, as the philosophy of history and the philosophy of nature. To this, therefore, is due the philosophism or panlogism which is characteristic of the system. This error was assisted by Hegel's want of clearness as to the nature of the empirical sciences. For him as for Kant, these remained sciences, that is to say, knowledge of truth, although imperfect knowledge of it. They therefore constituted even for him the material or the first step in philosophy. It is true that he also had other more acute and profound thoughts upon this subject. Amid a number of incidental observations, he emphasized the arbitrariness (Willkurlichkeit), with which those forms are affected; and this is tantamount to declaring their practical and atheoretic character. But instead of respecting this character, he decided upon surpassing it by means of a philosophic transformation of those sciences, which was not so much their death as pretended philosophies (a most true conclusion), as their elevation to the rank of particular philosophies by means of a mixture of empirical concepts and pure concepts, of abstract intellect and of reason. The erroneous tendency found nourishment and took concrete form in the idea of a Philosophy of nature, which Schelling had obtained, partly from Kant himself and partly had found in his own at first latent and then manifest theosophism. In this way, the system of Hegel became divided into three parts, a Logic-metaphysic, a Philosophy of nature and a Philosophy of Spirit, whereas it should on the contrary have unified Logic and the Philosophy of Spirit, and expelled the Philosophy of nature. By its internal dialectic, panlogism or philosophism was converted, even in Hegel himself, and still more among his disciples, into mythologism, and from the system of the Idea and of absolute immanence, because of the imperfections which they contained, there reappeared theism and transcendence (the Hegelian right wing).[18]
