But if among the common people, the devout, and occasionally also among people of culture, this highest art is not divested of its mythical environment, which still persists, although in a more ideal form, yet it has followed and still follows the general evolution of human ideas. The art of music was identified with song and with the mythical personality ascribed to it, of which these instruments were the extrinsic and harmonious echo; at first, like the other arts, it, was a religious conception and entity pertaining to the Church, but it gradually assumed a character of its own, was dissociated from the Church, and became a secular art, diverging more and more from the mythical ideas with which it had before been filled. When instruments increased in number, and became more perfect in quality; when harmony, strictly so called, was developed and became more efficient, instrumental music still continued to be the servant of vocal music, and was employed to give emphasis, relief, warmth, and colour to the art of song, which continued to be supreme. Song had its peculiar musical character, and the human voice, alone or in a chorus, might be regarded as the type of instrumental music, rendered more effective by the words which expressed the ideas and sentiments of such songs by harmonizing the various vocal instruments in accordance with their tones and varying timbre. Instrumental music, by the melodious harmony of artificial sounds, had however a vast field peculiar to itself, and an existence independent of the human voice. This was and is, in addition to its release from the bonds of myth, the necessary result of the evolution of this highest art.

Instrumental music, considered in itself, with the symphony as its highest expression, has been declared by a learned writer to be the grandest artistic creation, and the ultimate form of art in which the vast cycle of all things human will find its development. A symphony is an architectural construction of sounds, mobile in form, and not absolutely devoid of a literary meaning. Yet we must not seek in instrumental music for that which it cannot afford, such as the ideas contained in words. Any one must admit the futility of the attempt to give a dramatic interpretation or language to instrumental music, who reads the description attempted by Lenz and other writers of some of Beethoven's sonatas. Instrumental music does not lend itself to these interpretations, since it is an art with an independent existence. We have observed that in its first development it was used as an accompaniment to the voice, or associated with the movements of the body, or with the dance, and consequently had not the independence which was gradually achieved, until it culminated in the symphony. Instrumental music adds nothing to literature, nor to the expression of ideas and sentiments, but in it pure music consists, and it is the very essence of the art. Literature and poetry belong to a definite order of ideas and emotions; music is only able to afford musical ideas and sentiments. Instrumental music has its peculiar province as the supreme art which composes its own poems by means of the order, succession, and harmony of sounds; it delights, ravishes, and moves us by exciting the emotional part of our nature, and thus arouses a world of ideas which may be modified at pleasure, and which may, by the powerful means at its disposal, produce effects of which instruments merely used for accompanying the voice are incapable. When instrumental music was released from all servitude to other arts, as well as from all positive sense of religious emotions or mythical and symbolic prejudice, thought was able to create the art of sounds, which contains in itself a special aim and meaning.

We have thus reached the term of our arduous and fatiguing journey. We flatter ourselves that a truth has been gleaned from it, and this conviction is not, due to a presumptuous reliance on our powers, but on the conscientious honesty of our researches, combined with a great yet humble love of truth. Others, who are better endowed with genius and learning will judge of our success, and we shall willingly submit to their criticism and correction, so long as they are fair and unprejudiced and only aim at the truth. From animal perception, and the mental and physical fact into which it is to be resolved, we have traced the root which in man's case grows into a mighty tree; the first germ of all the mythical ideas of every people upon earth. The subjectivity of which animals and man are spontaneously conscious in every internal and external phenomenon, the subsequent entification of ideas, even after thought has attained to these more rational forms, are the great factors of myth in all its forms, of superstitions, of religions, and also of science. We have reduced all the normal and abnormal sources of these fanciful ideas to that single source which we have just indicated. Penetrating below the kingdom of man into that of animals, we have there discovered where the germ was formed, and this completes the doctrine of evolution and bears witness to its truth. The evolution of myth went through the regular process, by which it was formulated and simplified, until it was resolved into all the sciences and rational arts, and was thus transformed into a positive science, passing through an ulterior stage of myth and science before it took the definitive form of a purely intellectual conception.

We have seen that the source of myth is the same as that of science, since perception is the condition of both, and the process pursued is identical, although the subject on which the faculty of thought is exercised is changed. Therefore the problem of myth, which includes every achievement of the human understanding, and fills all sociology, is transformed into the problem of civilization. Thought has run its course in the vast evolution from myth to science, which is rendered possible by the permanence and duration of a powerful and vigorous race, and hence came the gradual transition from the illusions which involve the ignorance and servitude of the majority of the people to truth and liberty, since these are released from their earlier wrappings, and the human race rises to a sense of its nobility and highest good. We have considered this evolution as a whole and in its details, and have seen that every achievement of the human understanding passes through the same phases, and reaches the same goal. We have adduced witnesses to confirm our own observation from history and ethnography in general, apart from any bias for a religious and scientific system. We believe that in this way alone there can be any true progress in the science which we have undertaken to consider in this essay.

The result of the inquiry shows that by a slow yet inevitable evolution man rose from his primeval condition of error, illusion, and servitude to his fellow man, to that degree of truth and liberty of which he is capable: he was so made that he necessarily advanced to the grand height which has been attained by the most laborious and intelligent of the human race. He rises higher, and is more sensible of his own dignity, in proportion as he becomes, within the limits of his nature, the artificer of his own greatness and civilization. While many peoples have become extinct, others have, owing to their natural incapacity, remained in a savage and barbarous condition, while others again have attained to a certain amount of civilization, but their mental evolution has stopped short. Our own race, originally, as I believe, Aryo-Semitic, for it is possible that these two powerful branches were derived from a common stock, has persisted without interruption in spite of many adversities and revolutions, and has displayed in successive generations the progress of general civilization, and the goal which man is able to reach in his highest perfection of mind and body, favoured by the physical and biological conditions of climate. In this race, whether with respect to myth and science or to civilization, the theory of evolution has practically been carried out in all its phases and degrees.

Science and freedom were the great factors of civilization, or of progress in every kind of conceptions, sentiments, and social conditions: the first dissolved and destroyed the matrix of myth in which the intelligence was at first enveloped, and liberty, which was wholly due to science, made steady progress a matter of certainty. So that it may be said that the whole web of human history, so far as it consists in civilization or the progress of all good things, of the arts, and of every intellectual and material achievement, was the conflict of science, and her offspring freedom, against ignorance, and the despotism which results from ignorance, under all the social forms in which they are manifested. So that all good and wise men, sincere lovers of the dignity of mankind and of the welfare of society and of the individual, ought to feel a deep reverence and love for these two powers, and to be ready to give up their lives to them. For if—which in the present condition of the world is an impossible hypothesis—they were to fail, the human race would be irretrievably lost, since these are our real liberators from barbarism, which have upheld mankind in the struggle against it, under whatever name these principles have appeared.

I am aware that my theory will meet with many obstinate and zealous opponents in Italy, since I use the simple terms of reason and science, unqualified by other arguments, and I maintain the absolute independence of free thought. Opposition is the more likely since science and freedom have been held responsible for sectarian intemperance, for the disturbances of the lower orders, for the inevitable disasters, the social and intellectual aberrations both of the learned and of the common peoples: science and freedom are held to have repeated the wiles of the serpent in Eden. But I am not uneasy at the thought of such opposition, since the progress of the human race has been owing to the fact that men convinced of the truth took no heed of the superstitious and interested war waged against them, sometimes from ignorance of things in general and of the law which governs civilization, sometimes from honest conviction.

The falsity of the accusation so generally made against science and freedom will appear if we consider that all the benefits we now enjoy, civil, scientific, and material, and which are especially enjoyed by the men who inveigh most strongly against these two factors, are solely derived from science and freedom. Without them we should be in the civil, intellectual, and material condition of the kingdom of Dahomey, and in the savage and barbarous state of all primitive peoples. If the misunderstanding of truth or an imperfect science is injurious, it must not therefore be rejected. Science is the constant and vigilant generator of all social improvement, and the most formidable enemy of the tyranny of a despot, of an oligarchy, or of the multitude, whether it take a religious or secular form. Since sharp instruments are powerful aids to civilization and material prosperity, they are not to be altogether set aside because some persons die miserably by them. As I have always maintained, and now repeat with still stronger conviction, science and freedom, the ever watchful guardians of the human race, are and must always remain the sole remedies for the evils which threaten us. I do not dispute the beneficent influence of other factors combined with these, but, taken alone, they would be powerless, and if science were eclipsed they would be transformed into fresh causes of servitude and ignorance, as it has often appeared in past times when the laws of science and of freedom have been set at nought. I therefore declare science and freedom to be the portion of all, and they should be as widely diffused as possible, since the way to knowledge and a worthy life is open to all men. It is a blasphemy against heaven and earth to presume, in the so-called interest of civil order, to keep the majority of the people in the ignoble servitude of ignorance, and men do not perceive that they thus become ready for any disturbance, and the tools of rogues and agitators.

I hope and pray that reverence for science and freedom may ever increase in Italy. It will be an evil day for her if such reverence be lost, and she will become with every other people in like case a wretched spectacle, and will fall into such abject misery as to become the laughing-stock of every civilized nation. It will be understood that I do not erect science and liberty into fetishes to be generally adored: they are only sacred means to a more sacred end, namely, to enable men to practise and not merely to apprehend the truth, which in other words is goodness. Science and freedom are valuable only so far as they teach, persuade, and enable us to improve ourselves and others; to exercise every private and public virtue; to claim only what is due to ourselves, while making the needful sacrifice to the common good; to have a respect for humanity, and to venerate knowledge only so far as it is combined with virtue; to attempt in every way to alleviate the miseries of others, to deliver their minds from ignorance and error; to do right for its own sake without coveting rewards in heaven or on earth; to submit to no dictation but that of truth and goodness.

With these sacred objects in view, whatever may be said to the contrary, we shall, in addition to the ineffable fruition of truth for its own sake, ever draw nearer to the ideal of the human race, and the time will come when an apparent Utopia shall be actually realized, in accordance with the mode and process of growing civilization. Not by excesses, tumults, and folly, but by unshaken firmness and tenacity we shall promote science and freedom. If this modest essay has done anything to show the necessity of such culture, and in what way science and freedom, and these two factors only, have brought forth fruit throughout the history of the human race, my labour will be richly rewarded, and I may say with satisfaction—dies non perdidi!
