We need not point to the object of logic, or concept, as we did in a former chapter to the object of æsthetics, or intuition. The writing of this book implies a belief in its existence, and we could take practically any page of it as an example of what we mean by concept, or logical knowledge. We shall not therefore pause to confute logical scepticism, except by repeating the old argument that it is impossible to deny the existence of the concept except through the formulation of a concept. Such affirmations as that there is no other knowledge than the æsthetic one, or the one which is given by the ineffable intuition of the mystic, or by practical fictions, are in their turn neither æsthetic knowledge nor mystical intuitions, nor practical fictions, but affirmations, however contradictory in themselves, of a universal value and of an absolute character, that is, concepts. Through them, it is possible immediately to distinguish the logical form of knowledge, as represented by such affirmations, from the æsthetic or representative one, from the sentimental or practical state of mind of the mystic, and from those concepts which are mere empirical fictions. It is evident, in this last instance, that the theory of the fiction cannot be a new fiction, but must belong to an activity of a different kind, the logical activity, whose value is truth.
Of those three forms of logical scepticism, æstheticism, mysticism, and empiricism, the third one leads us to the distinction between the logical concept and the scientific concepts, or fictions. The logical or pure concept is beyond all individual representations, and must therefore not contain any particular representative element; but, on the other hand, being the universal as opposed to the individuality of representations, it must refer to all and each of them. If we think, for instance, of the concepts of beauty, truth, quality, development, and such like, it will be impossible for us to represent or imagine a sufficiently large fragment of reality that will exhaust them, or such an infinitesimal one as will not admit them. This is what is meant by saying that the concept is at the same time universal and concrete, or, in other words, that it is transcendent in respect to every single representation, and yet immanent in all of them. A third characteristic of the pure concept, besides those of universality and concreteness, is that of expressivity: being a product of knowledge, it must be expressed and spoken, and cannot be a dumb act of the mind, such as practical acts are.
The conceptual fictions, or, as Croce called them on account of their non-theoretical character, the pseudo-concepts differ from the pure concept in being either concrete and representative but not universal, or universal without any possible reference to individual representations, that is, without concreteness. The first class is that of empirical concepts, which contain some objects or fragments of reality, but not the whole of reality: such as the concepts of house, cat, rose. The second is that of abstract concepts, which contain no object or fragment of reality: such as those of triangle in geometry or of free movement in physics. The first are real, but not rigorous, the second rigorous, but unreal. Neither the ones nor the others can be considered as mistaken concepts or errors, since after having criticised them from a logical point of view, we still continue to use them for what they are; nor as imperfect concepts, and preparatory to the perfect ones, since their formation presupposes the existence of the perfect and rigorous ones: it would be impossible to conceive the house, the rose, the triangle, before conceiving quantity, quality, existence, and other pure concepts. It is true that in the actual development of thought, conceptual fictions have again and again given birth to true concepts; but in that case they have lost their intrinsic nature, and have assumed the characters of the genuine logical activity. In order to understand the proper function or nature of the conceptual fictions, it is necessary to fix our attention on the moment of their formation, which is practical and not logical. Their justification lies in their practical end and in their usefulness: they are instruments by the help of which we can recall with a single word vast groups of representations, or which indicate in a single word what kind of operation is required in order to find certain representations. The act of forming intellectual fictions is neither an act of knowledge nor of not-knowledge; logically, it is neither rational nor irrational (true or untrue); its rationality is of another order, practical and not logical. The activity which produces pure concepts, and that which produces empirical or abstract concepts, have been called respectively Reason and Abstract Intellect, or Intuition and Intellect; to which terminology Croce objects that the word intellect is certainly inappropriate to a non-theoretical activity. Croce himself is in no need of a new name for it, since he considers it one with the general practical activity, will or action.
The definition that we have given of the pure concept seems to clash against an insuperable difficulty arising from the multiplicity of concepts. If the concept is an elaboration of reality as a universal, how can we admit the existence of more than one concept? Beauty and truth are both concrete universals, and yet they are not the same universal: they have the same logical form, but they denote different aspects of reality. If this variety of the concepts, that is, of the aspects of reality, were insuperable, we should fall from the irreducible multiplicity of representations into a not less irreductible multiplicity of concepts, which would in the end justify a new logical scepticism and take us back to a mystical solution of the problem of the unity of reality. The passage from the multiple universals to the true universal would be logically impossible, and to be performed only by the help of some sort of mystical intuition.
The solution of this difficulty has already been hinted at in the discussion of the relations between intuition and concept, and between knowledge and will. The theory of the successive grades of reality, in their progressive implication, is the true form of the concept. Croce affirms the unity of reality, as a consequence of the unity of the concept, of the form through which only reality is known. But if we suppress the distinction, the unity that we reach is an empty and ineffable one: a whole is a whole only inasmuch as it has parts, as it is parts; a unity can be thought only through its distinctions. Therefore the unity and the distinctions are both necessary to the concept: the distinctions are not something outside the concept, but the concept itself, which is a unity of distinctions. The mind or spirit is one, but it is impossible to think of it as a pure and simple unity, outside of the forms in which it realizes itself, and of these forms in their necessary relations. Which is but a more comprehensive way of saying what we have already said speaking of one of those forms in particular, the æsthetic one, that it is impossible to conceive any of them except by determining its relations with the others.
It is necessary, however, not to convert these distinctions of the concept into abstractions: by approximation, and for a practical purpose, we can speak of a given action as a theoretical or practical one, an economic or moral one. In fact, in every fragment of reality we find the universal, and therefore all the forms of the universal. But on the other hand it is impossible to think any concrete datum, and to recognize it as an affirmation of the spirit as a whole, unless we distinguish each of its aspects in the most rigorous fashion. We shall then have a criticism of art and poetry, from the æsthetic point of view; or of philosophy, from the logical one; and a moral judgment which takes into account only the individual moral initiative. The distinctions of the concept are then used as directing principles of thought, but not, in the way empirical concepts are used, as criteria for a classification of objects; nor, again, as characteristics of epochs of actual historical development, which in the end reduce themselves to types of material classification.
Croce's theory of the unity and distinctions of the concept coincides with the old division of concepts into universal, particular, and singular ones. The true logical definition is reached only by determining the singularity of a distinction in relation with the other distinctions (particularity), and with the whole (universality). For instance, the concept of beauty is intuition (singularity), knowledge (particularity), and finally spirit or mind (universality). The symbol corresponding to this peculiar relation is not that of a fine or succession, but of a circle: there is not a first and a last term of the series, a beginning and an end, but a perpetual revolution, in which every distinction in turn may appear as the beginning and the end of the series. Art or philosophy, knowledge or action, may be postulated with equal reason as the end of the spirit: the true end, however, is not any of the particular forms, but only the spirit or mind or reality as a whole.
Readers who are familiar with Hegelian logic will at once perceive the difference between Croce's and Hegel's treatment of logical distinctions. There is no attempt on the part of Croce to apply to them the dialectic process, which pervades the whole of Hegel's philosophy, and which is retained by Croce only in its legitimate sphere which is not that of distinctions but of oppositions. The dialectic process, of which the remote ancestor is Plato, and the more immediate forbears those Renaissance philosophers, Cusanus and Bruno, who more or less obscurely affirmed the principium coincidentiæ oppositorum, only with Hegel reaches its rigorous logical expression. The most famous instance of its application is to be found in Hegel's formula of the opposition of being and non-being, and of their unity in the becoming: the pure being is identical with the pure non-being, or, to say the same thing in different words, we cannot think the one without the other, and we do actually think the one and the other when we think the actual reality, which is neither being nor non-being, but becoming. Being and non-being are a true couple of opposites, as ideal and real, positive and negative, value and non-value, activity and passivity, and so on. By the application of the dialectic process, all these couples are shown to be not couples of concepts, but single concepts, each couple containing the affirmation and the negation of a single concept. Croce's criticism of Hegel is founded on an interpretation of the dialectic process as logically valid for such couples only, and inapplicable to the distinctions of the concept, or to empirical and abstract concepts; and this criticism, while emphasizing the importance of Hegel's main contribution to philosophical thought, sweeps away at one stroke all that in his philosophy has generally been considered as most distinctly Hegelian both by his followers and by his adversaries.
Croce's interest in such couples of opposites as those that we have mentioned is very far from being as keen as Hegel's. Their dialectic solution into single concepts is implicit in every phase of Croce's philosophy. This can best be seen in the constant interchange of such words as spirit and reality; each of them, when taken by itself, a pure, formal spirit, and a pure, material reality, are meaningless, while, once they have been correlated, both indicate the same concept, the spirit perpetually realizing itself in the concreteness of life: a formula which contains the whole of Croce's immanentism. But within the distinctions of the concept, the dialectic process is constantly applied by Croce to such oppositions as those of good and evil, true and false, beautiful and ugly, which are nothing but the double aspect, affirmative and negative, respectively, of the concepts of goodness, and truth, and beauty. We need only recall what we have said of Croce's conception of æsthetic value, and of value in general. The dialectic process is the logical structure of Croce's concept of value. The positive element of each concept is the only real one, and a negative judgment of value is not a purely logical judgment, but a statement to which is added the expression of a desire or of an exigency. If we say: A is immoral, we mean: A follows his own immediate pleasure (a logical statement), and also: A ought to follow a higher end (the expression of a desire). A positive judgment of value, on the other hand, coincides entirely with a logical judgment, or a statement of fact. The opposition of value to fact is of the same kind as that of spirit to reality; verbal and apparent and not logical and real. The underlying reality of the opposition can be grasped only through the distinction; what in the opposition is a negative and therefore a mere abstraction can never be anything but a positive value of another order, a distinct form of activity. The action that we have judged as morally evil, if it is an action at all, belongs to the economic order, is economically rational, directed towards a particular end which confers on it its particular value; and the same applies to all the other categories of reality, in which error and evil cannot be introduced except by the substitution of one form for the other. It is impossible to distinguish a concept from its opposite as two concepts; but when a distinction is introduced, the opposition loses its negative character, and identifies itself with a distinct but positive value. Error and evil as such are never present except in the act that transcends them, in the conscience that, realizing itself in a higher sphere, turns against them and condemns them. It is superfluous to point to the importance that this process lends to the distinctions themselves, which are now seen at last not as mere logical instruments, but as the actual differentiations of reality, the necessary conditions of all life and progress.
