This method of approach to the logical problems, although unusual in our times, and antagonistic to the general tendencies of our culture, is not only, as its opponents assume, that of Kant and Hegel, but that of the whole tradition of European philosophy, beginning with Socrates, Plato, and Aristotle. It was only in epochs of philosophical decadence that logic reduced itself to a mere formalism or instrumentalism, ism, to a doctrine of the means of thought, as opposed to its proper function, which is that of inquiring into the nature of thought, and therefore, since there is no way by which we can reach reality except through thought, into the nature of reality itself. To Croce, as before him to Hegel, the philosophical tradition is not a capricious sequel of unrelated speculations, but a series of connected efforts through which the human mind becomes progressively conscious of its own functions and structure. Nothing is more alien from him than that type of philosophical criticism, which exhausts itself in an attempt at reducing under a common denominator apparently similar solutions of problems, which in fact are profoundly different in their historical determination: but this consciousness of the historical factor in philosophy, far from breeding in him a sense of scepticism and of the relativity of truth, impels him to consider every effective thought as a necessary moment of truth, and to represent therefore the succession of effective thoughts, critically separated from what in the various concrete philosophies is merely postulated or imagined, as a perpetual integration of truth. This attitude explains why the immediate foundations of Croce's logic should be Kant's a priori synthesis and Hegel's dialectic, that is, the highest stages of the development of European thought before the positivistic anti-metaphysical reaction which swept away for a time, not the last traces of transcendental metaphysics only, but philosophy and logic itself; and why also, among all the recent critics of Kant and Hegel, Croce should be one of the keenest and sharpest. His sure grasp of fundamentals made it easy for him to demolish all that is artificial and unessential in their systems; as is particularly evident in the case of Hegel, who emerged from Croce's criticism as the discoverer of one great principle and at the same time the creator, through the misapplication of the same principle, of many a false science.
