The concept does not exist outside its verbal expression, but the relation between logical thought and language, because of the purely æsthetic or intuitive nature of language, is not of the rigorous character which is postulated by the Aristotelian logician, and, in more recent times, by the student of symbolic logic, who both assume language to be an essentially logical function. It would be impossible for Croce to fall into that extreme of idealism which is the common vice of the verbal realist, for whom propositions, judgments, or syllogisms have a kind of absolute reality of their own, independent of the mind that thinks them. It may seem paradoxical to assert that nowhere is Croce's realism more apparent than in his treatment of the verbal forms of the concept; and yet his criticism of the old logical principles and forms, running parallel to that of the rhetorical categories and genres in the field of æsthetics, allows him to reach the actual workings of the logical activity with much greater intimacy than is possible through any kind of formalistic logic. The logical judgment, or concept, appears in two main forms: the definition, and the individual judgment. In the definition, the subject is one with the predicate, both being universal; in the individual judgment, the subject is an individual, the predicate a universal. "The intuition is the æsthetic form of the spirit," is a definition; "The _Divine Comedy_ is poetry," is an individual judgment. The individual judgment is one with the perception, or perceptive judgment, with the historical judgment, and, for the reason given before, with the positive judgment of value; it is the last and most perfect form of knowledge. But the distinction between the definition and the individual judgment is not an ultimate and irreducible one. The concrete logical act is always an individual judgment, that is, the affirmation of the unity of the individual and the universal in relation to a particular subject; and every definition is an individual judgment inasmuch as it cannot be but the solution of a particular problem, individually and historically determined. The particular problem, the group of facts, from which a particular definition arises, is the individual subject of which the definition predicates the concept. This identification of the definition and the individual judgment disposes of the familiar distinctions of formal and material truths, of truths of reason and of fact, and of analytical and synthetical judgments; which all are reduced to mere abstractions, partial aspects of the only logical act, consisting in the thinking of the pure concept, as a concrete universal.
