Logic as the Science of the Pure Concept

by Benedetto Croce

On this unity and homogeneity is based the demand so often made (especially in the second half of the nineteenth century) for the extension of the method of the natural sciences to the sciences of the spirit or moral sciences, the orbis intellectualis, for a naturalistic treatment of the productions of language and of art, or of political, social, and religious life. Thus were originated or prophesied a Psychology, an Æsthetic, an Ethic, a Sociology, methodo naturali demonstratae. It was necessary to draw the attention of those makers of programmes and advisers (apart from the evil philosophic intentions, positivist or materialistic, which they nourished in their bosoms) to the superfluity of their demand, and gently to reprove them with the old phrase: Quod petis in manu habes. Since man was man and constructed pseudoconcepts and empirical sciences, these naturalistic classifications have never been limited to animals, plants, and minerals, nor to physical, chemical, and biological phenomena, but have been extended to all the manifestations of reality. Naturalistic Logic, Psychology, Linguistic Sociology and Ethics have not awaited the nineteenth century ere they should open to the sun. And (without going too far back in time, or leaving Europe) they already bore flower and fruit in the Sociology (Politics) of Aristotle, in the Grammatics of the Alexandrians, in the Poetics and Rhetoric of Aristotle himself, or of Hermagoras, of Cicero, or of Quintilian, and so on. The novelty of the nineteenth century has principally consisted in giving the names social Physics, or the physico-acoustic science of language to what was once more simply, and perhaps in better taste, called otherwise. But in saying this we do not wish to deny that certain naturalistic work has been far more copious in the nineteenth century than in Greece, and that naturalistic methods have not been applied with singular acumen and exactitude in those fields of study. Linguistic affords a case in point, with its phonetic laws, by reason of which it moves so proudly among its companions.

Historical basis of the natural sciences.

The natural sciences and the empirical concepts which compose them appear therefore like a tachygraphic transcription upon living and mutable reality, capable of complete transcription only in terms of individual representations. But upon what reality? Upon the reality of the poet, or upon the clarified and existentialized reality of—the historian? The constructions of the natural sciences take history for their presupposition, just as judgments of classification take individual judgments. Were this not so, their economic function would have no way of expressing itself, from lack of matter whereon to work. To employ the easy example already given, it would be of no use to the zoologist to construct types and classes of animals that were certainly conceivable, but non-existent. For while those types and classes would distract the attention from the useful and urgent task of summarizing reality historically given and known, they would not exhaust the possibilities, which are infinite And if it appear that imaginary animals are sometimes classified, as for example griffins centaurs, Pegasi, and sirens, it is easy to see that this is not done in Zoology, but in another naturalistic science,—comparative Mythology, in which not animals but the imaginings of men are really classified. These too are historical facts, because they are imaginings or fancies historically given. They are not combinations of images which no people has ever dreamed of, nor any poet represented, for such, as has already been said, would be infinite in number and food for mere diversion.

The question as to whether history is the foundation or the crown of thought.

History, which has philosophy for its foundation, becomes in its turn foundation in the natural sciences. This explains why, with the controversy as to whether history be a science or an art, there has always been inextricably connected the other question as to whether history be the foundation of science or science the foundation of history. The question finds a solution in the solution of the ambiguity of the term "science," which is used indifferently, sometimes in the sense of philosophy, sometimes in that of the natural sciences. If science is understood as philosophy, history is not its foundation, indeed philosophy is the foundation of history. Both mingle and are identified in the sense already explained. If science is understood as naturalistic science, then history is its necessary foundation or precedent. Certainly, naturalistic classifications are also reflected in historical narrative; but, as we have seen, they do not perform a constitutive function in it; they are of merely subsidiary assistance.

Naturalists and historical research.

But since history is the foundation of the natural sciences, and the special treatment of perceptive material or historical data by these sciences does not possess theoretic value, but is valuable merely as a convenient classification, it is clear that the whole content of truth of the natural sciences (the measure of truth and reality that at bottom they contribute) is history. Therefore it is not without reason that the natural sciences or some of them have been called in the past natural history. History is the hot and fluid mass, which the naturalist cools and solidifies by pouring it into formal classes and types. Previous to this manipulation, the naturalist must have thought as a historian. The matter thus cooled and solidified for preservation and for transport has no theoretic value, save in so far as it can again be rendered hot and fluid. Similarly, on the other hand, it is necessary to revise continually the classifications adopted, returning to the observation of facts, to simple intuitions and perceptions, to the historical consideration of reality. The naturalist who makes a discovery, in so far as he is a discoverer of truth, is a historical discoverer; and revolutions in the natural sciences represent progress in historical knowledge. Lamarckianism and Darwinism may serve as an example of this. Naturalists (and we use the word in its ordinary meaning, applying it to those who explore this "fair family of plants and animals," and what is called in general the physical world) feel themselves somewhat humiliated when described as classifiers careless of truth. But if such classification is exactly what the natural sciences accomplish from the gnoseological point of view, yet naturalists as individuals and as corporations of students exercise a far more substantial and fruitful function. The historical foundation of the life of the natural sciences is also found in the fact that a change of historical conditions sometimes renders, if not wholly useless, at least less useful, certain classifications made with the object of controlling conditions of life remote from us, or perceptions concerning life that have now been abandoned. This has occurred with regard to the classifications of alchemy and of astrology, and also (passing on to examples from other empirical sciences) to the descriptive and casuistic portions of feudal law. When the book is no longer read, the index also falls into disuse.

The prejudice as to the non-historicity of nature.

The strangest of statements, that nature has no history, comes from forgetting the historical foundation of the natural sciences, from ignorance that it constitutes their sole truth, and from attributing theoretic importance to classifications which have merely practical importance. In this case, nature signifies that reality, from man downwards, which is empirically called inferior reality. But how, if it is reality, is it without history? How, if it is reality, is it not becoming? And further, the thesis is confuted by all the most attentive studies of so-called inferior reality. To limit ourselves to the animal kingdom, a century before Darwin the acute intellect of the Abbé Galiani shook itself free of this prejudice as to the immobility of animals. He remarks in certain places about cats: "A-t-on des naturalistes bien exacts qui nous disent que les chats, il y a trois mille ans, prenaient les souris, préservaient leurs petits, connaissaient la vertu médicinale de quelques herbes, ou, pour mieux dire, de l'herbe, comme ils font à présent? ... Mes recherches sur les mœurs des chattes m'ont donné des soupçons très forts qu'elles sont perfectibles; mais au bout d'une longue traînée de siècles, je crois que tous que les cliats savent est l'ouvrage de quarante à cinquante mille ans. Nous n'avons que quelques siècles d'histoire naturelle: ainsi le changement qu'ils auront subi dans ce temps, est imperceptible."[3] This slight perceptibility of the relative changes of what is called nature or inferior reality has contributed to that prejudice (not to mention the confusion between the fixity that belongs to naturalistic classifications and reality, which is always in motion). Nature appears to be motionless, just because of the slight interest that we take in the shadings of its phenomena and in their continuous variation. But not only is nature not motionless, but it is not even true that it proceeds (as the poet says) "with steps so slow that it seems to stand still." The movement of nature or inferior reality is fast or slow, neither in less nor greater degree than human reality, according to the various arbitrary constructions of empirical concepts which are adopted, and according to the variable and arbitrary standards of measurement which are applied to them. We watch with vigilant eye every social movement that can cause a variation in the price of grain or the value of Stock Exchange securities; but we do not surprise with equally vigilant eye the revolutions that are prepared in the bosom of the earth or among the green-clad herbs of the field.

The philosophic foundation of the natural sciences, and the efficacy of the philosophy that they contain.
