Necessity of the historical element in philosophy.

The necessity of philosophy as a condition of history has been made evident from the preceding considerations. It is now necessary to affirm with no less clearness the necessity of history for philosophy. If history is impossible without the logical, that is, the philosophical, element, philosophy is not possible without the intuitive, or historical element.

For a philosophic proposition, or definition, or system (as we have called it), appears in the soul of a definite individual at a definite point of time and space and in definite conditions. It is therefore historically conditioned. Without the historical conditions that demand it, the system would not be what it is. The Kantian philosophy was impossible at the time of Pericles, because it presupposes, for instance, exact natural science, which developed from the Renaissance onward. And this presupposes geographical discoveries, industry, capitalist or civil society, and so on. It presupposes the scepticism of David Hume, which in its turn presupposes the deism of the beginning of the eighteenth century, which in its turn is connected with the religious struggles in England and in all Europe in the sixteenth and seventeenth centuries, and so on. On the other hand, if Kant were to live again in our time, he could not write the Critique of Pure Reason without modifications so profound as to make of it, not only a new book, but an altogether new philosophy, though containing within itself his old philosophy. Stiff with old age, he was even capable of ignoring the interpretations and developments of Fichte, and of ignoring Schelling. But to-day he could not ignore either of these, nor Hegel, nor Herbart, nor Schopenhauer. He could not even ignore the representatives of the mediæval philosophy, which followed the classical period of modern philosophy; the authors of positivist myths, Kantian and Hegelian scholastics, the new combinations of Platonism and Aristotelianism, that is, of pre-Kantian with post-Kantian philosophy, the new sophists and sceptics, the new Plotinians and Mystics, nor the states of soul and the facts, which condition all these things. For the rest, Kant truly lives again in our days, with a different name (and what is individuality, countersigned with the name, save a juxtaposition of syllables?) He is the philosopher of our times, in whom is continued that philosophic thought, which once took, among others, the Scoto-German name of Kant. And the philosopher of our day, whether he will it or no, cannot abandon the historical conditions in which he lives, or so act as to make that not to have happened which happened before his time. Those events are in his bones, in his flesh and blood, and it is impossible to drive them out. He must therefore take account of them, that is, know them historically. The breadth of his philosophy will depend upon the breadth of his historical knowledge. If he did not know them, but merely carried them in him as facts of life, his condition would not differ from that of any animal (or of ourselves in so far as we are animals or beings that are, or rather seem to be, completely immersed in will and practice). For the animal is precisely conditioned by the whole of nature and the whole of history, but does not know it. The meaning of the demand must therefore be understood that a truthful answer may be obtained. History must be known in order to obtain the truth of philosophy.

Historical quality of the culture required in the philosopher.

This demand is usually expressed in the formula that the philosopher must be cultured, though it is not clear what is the quality of this culture that is said to be requisite. Some, especially in our own days, would wish the philosopher to be a physiologist, a physicist, a mathematician, that is, that his brain should be full of abstractions, which are certainly not useless (everything is worth knowing, even the triviality of girls, for even that is a part of life and of reality), but which are in no direct relation to that form of knowledge which must be the condition of philosophy. This form of knowledge is, on the contrary, history; or, as it is said (with an a potiori intention), the history of philosophy, which of necessity as the history of a moment of the spirit, includes all history in itself, as we have shown above, when criticizing the divisions of history. That is to say, it is necessary to know the meaning of the problems of our own time, and this implies knowing also those of the past, in order not to take the former for the latter and so cause inextricable confusion. And to the extent that they can be of use according to the requirements of the problem, we must know also the natural, physical, and mathematical sciences. But we must not know them as stick and develop them as such, but rather as historical knowledge concerning the state of the natural sciences, of physics, and of mathematics, in order to understand the problems that they help to raise for philosophy.

Apparent objections.

It is vain to set against this the example of great philosophers without historical culture, as it is vain in the case of the necessity of historical knowledge for æsthetic criticism to bring forward instances of those who, although without any historical knowledge, have yet given far more true and more profound judgments upon art than the historically learned. If those judgments are true, then the critic supposed to be ignorant of history is not ignorant of it. He has somehow absorbed, scented in the air, divined with rapid perception those actual facts that were applicable to the given case. And, on the other hand, the so-called learned man will not be cultured, because his erudition is not lively and synthetic. The same happens in the case of those acute philosophers, who are said to be ignorant of the world and of history and of the thoughts of other philosophers. It cannot be denied that much or little history may be learned outside the usual course of teaching by manuals and by orderly mnemonic methods. But here, too, the exceptional mode of learning confirms the rule and does not obviate the usefulness for the majority of the customary modes of learning. On the other hand, if he who is said empirically to be without historical knowledge, but is not so in a given instance, should nevertheless prove really ignorant in other instances, where his unusual way of learning is not open to him, his philosophy also suffers. For this reason, those philosophers who are ignorant of history exhibit deficiencies that have often been deplored. They burst open doors already opened, they do not avail themselves of important results, they ignore grave difficulties and objections, they fail to probe certain problems sufficiently deeply, and show themselves too insecure and too superficial in others, and so on. Thus is the customary learning of history avenged upon them: and Herbert Spencer, who would never read Plato or Kant, is rejected, while Schelling and Hegel are again in the hands of students.

Communication of history as changing of history.

Philosophy also changes with the change of history, and since history changes at every moment, philosophy at every moment is new. This can be observed even in the fact of the communication of philosophy from one individual to another by means of speech or writing. Change at once takes place in that transmission. When we have simply created again in ourselves the thought of a philosopher, we are in the same condition as he who has enjoyed a sonnet or a melody, by suiting his spirit to that of the poet or composer. But this does not suffice in philosophy. We may attain to ecstasy by the recitation of a poem or the execution of a piece of music, just as it is, without altering it anywhere. But it does not seem possible to possess a philosophic proposition, save when we have translated it, as we say, into our own language, when in reality, relying upon its results, we formulate new philosophic propositions and solve new problems that have presented themselves in our souls. For this reason no book ever completely satisfies us. Every book quenches one thirst, only to give us a new one. So true is this, that when we have finished reading or are in course of reading, we often regret that it is impossible to speak with the author. We are led to say, like Socrates in the Phædrus,[1] that written discourses are like pictures and do not answer questions, but always repeat what has already been said. Or we lose patience, like that Paduan professor of the fifteenth century, who, commenting on the jurist Paolo, and annoyed at the difficulties, exclaimed at a certain point: "Iste maledictus Paulus tam obscure loquitur ut, si haberem eum in manibus, eum per capillos interrogarem!" But if instead of the dumb book, we had before us a living man, a Paolo obliged to be clear, the process would still be the same: his speech would be translated into our speech, his problem would arouse in our spirit our own problem.

The perpetuity of change.
