The two main directions of modern thought, or rather of all human thought, are thus represented in the naturalism of Bruno and in the spiritualism of Campanella, at the conclusion of the Renaissance, respectively prefiguring the pantheism of Spinoza and the rationalism of Descartes, that is, the two systems through which similar conceptions became active and effective in all subsequent developments of European philosophy. And it is useful to recall their names as an introduction to the exposition of the ideas of a modern Italian philosopher, because we are to-day only too prone to identify certain forms of common European thought, originating from Greece and from Italy, with what was only their last expression in the great idealistic movement in Germany in the nineteenth century; where Bruno and Spinoza reappear in Schelling, and Campanella and Descartes, through the intermediary of the English thinkers of the eighteenth century, in Kant and Hegel.

I am not trying to establish an Italian pedigree for the kind of philosophy to which Croce belongs: nowhere are national distinctions so futile as in the history of thought. But the Italy of the Renaissance shares with India and with Greece the purely material privilege of having given birth to a vision of the world and its problems, which is national only in the sense that it was elaborated for a certain time at least by minds belonging to a single nation. The value of that vision, however, does not reside in any tribal or national characteristic, but in those elements of universality, which made of the Italian culture of the Renaissance, and of its inherent logic, the basis of all modern European culture. What can still be recognized as peculiarly Italian, or French, or English, or German in the thought of modern philosophers, is not that phase of truth, which may be present in it, but the element of prejudice, of crowd-mindedness, of spiritual inertia, which even the greatest among them have in common with their weaker brothers.

In Bruno and Campanella we find an interest in certain problems of thought, which we may call either religious or, more technically, ontological: the problems of the relations of being and knowing. In Vico, who is infinitely nearer to Croce in intellectual temper, the centre of interest is shifted. Vico is apparently satisfied with Catholicism as a religion; and he spends all his efforts in creating a philosophy out of the purely humanistic and historical side of Renaissance culture. And yet, long before Kant's Prolegomena, he foresees the necessity of the new metaphysics being the metaphysics, as he says, of human ideas, and his theory of knowledge is founded on a principle which bears an external resemblance to certain aspects of pragmatism, but is in reality of a quite different, and much deeper, character: that of the interchangeability of the factum with the verum, of that which we make with that which we know. It was a commonplace of the schools that perfect science is to be found in God only who is the author of all things: Vico transfers this logical formula from God to man, and applies it, in the first stage of his thought, to mathematics, which appears to him as of man's own making, in a narrow and abstract sense, and later to the whole world of history and human thought and action, which, in a much truer and broader sense, is made by man.

Vico was brought to this second and final form of his theory of knowledge by his studies on the history of law, of religion, of language and poetry: his philosophy is essentially a philosophy of the moral sciences, of philology in its widest meaning. And the whole of his speculation, in his Scienza Nuova takes the shape of an enquiry into the origins and development of human society: not essentially of a sociology, an empirical and inductive science of man (though this aspect is undoubtedly also present in his mind), but rather, through "the unity of the human spirit that informs and gives life to this world of nations," of an ideal and eternal history of mankind, a philosophy of the human mind.

A contemporary and an antagonist of Descartes, Vico is one of the last among European philosophers to embrace practically the whole range of contemporary culture. But while Descartes lays the foundations of his theory of knowledge on the certainty of mathematical method, mistrusting the imperfection and vagueness of any other form of science, Vico is enabled by his intimate contact with rhetoric and history, with that philology which had been the soul of the intellectual life of the Renaissance, and which through the erudition of his century was preparing the historical consciousness of the following one, to anticipate the general principles of idealistic philosophy and, on the theories of art, of language, of law, of religion, as well as on a large number of particular historical problems, the general development of subsequent European thought.

At a later stage in our exposition, we shall examine in greater detail the indebtedness of Croce to Vico, especially as regards the theory of art and language; but the similarities of circumstance and of temperament between the two philosophers are already apparent. Both Vico and Croce came to philosophy through erudition and philology; and in Croce as well as in Vico, the fundamental philosophic attitude, their theory of knowledge, their idealism (what in the case of Croce has been called his Hegelism), is the intrinsic and necessary logic of the same humanistic tradition, the natural outcome of the centering of their intellectual interests on the history of the human spirit rather than on the mathematical or natural sciences. It is only after Descartes and Vico, and through the independent progress of scientific thought in the last two centuries (during the Renaissance, science is constantly in contact with philology, and there is no scientist who is not also a humanist)—that the two divergent attitudes of mind which we have seen exemplified in Bruno and Campanella, naturalism and spiritualism, are finally divorced from each other, and respectively linked with the scientific or with the historical aspect of modern European culture. Rationalism, intellectualism, positivism, pragmatism, on one side, are the more and more rarefied logics of science, in its progressive estrangement from the humanities; and because of the increasing prestige of scientific thought, we see them making constant inroads even in the fields of the historical and philological disciplines. Idealism, on the other side, represents in its many forms the central tradition of European culture, and is heir to the religious thought of the Middle Ages as well as to the humanism of the Renaissance; but in many of its exponents, and to my mind, even in some aspects of Croce's philosophy, it suffers from that same condition of things which is the cause of the poverty and narrowness of the so-called scientific philosophies: from that inability to grasp both nature and the spirit of man, the world of science and the world of history, which is a characteristic of our times. The recurrence of the realistic position, after every great affirmation of idealistic philosophy, is certainly not the mere recurrence of error, the obstinate permanence of human folly after the pronouncements of wisdom, but rather the restatement of a logical exigency which cannot be entirely satisfied and disposed of by any of the idealistic solutions of the problem of reality. Idealism and realism in modern philosophy are two distinct and divergent elaborations of different fields of modern culture: that unity of the intellectual vision, which is perfect, within its accepted limitations, in mediæval philosophy, and which is never entirely lost sight of in the thought of the Renaissance, is the goal towards which both realism and idealism continually tend, but which will not be reached by either, until the disiecta membra of our intellectual consciousness will be brought together through a higher synthesis than the one from which they fell apart at the end of the Renaissance.

We are now in a position to understand why it would be vain to look in the work of Croce for either an organized synthesis of scientific thought, understood as a means through which the mind of man grasps the reality of nature, or a system of metaphysics attempting to explain the facts of our human life by reference to an order of superhuman and supernatural realities. These are two types of philosophy, a criticism of which is implicit in every step of Croce's philosophical career, as well as in the quality of his philosophical ancestry. But in their place we shall find a series of meditations on the problems of the human spirit in its actual historical development; on the distinctions and inter-relations of the various forms of spiritual activity, not as they appear, in a purely abstract and external consideration, to the eye of the psychologist, but as they reveal themselves in the intimacy of those spiritual and historical processes, in which man creates at the same time his own being and his own truth. As we have stated already, the philosophy of Croce is essentially a philosophy of the humanistic tradition, of that Italian and European tradition the consciousness of which seems to be fast disappearing even among those who consider themselves as its exponents and defenders; and which in his thought not only justifies and understands itself, but brings that justification and that understanding to a greater depth, to a more comprehensive clarity, than it ever reached during the many centuries of its existence.
