what the ugly? To what unions of tones, colours, sizes, mathematically determinable? Such inquiries are as if in Political Economy one were to seek for the laws of exchange in the physical nature of the objects exchanged. The persistent fruitlessness of the attempt should have given rise before long to some suspicion of its vanity. In our times, especially, necessity for an inductive Esthetic has been often proclaimed, of an Esthetic starting from below, proceeding like natural science and not jumping to its conclusions. Inductive? Inductive? But Esthetic has always been both inductive and deductive, like every philosophical science; induction and deduction cannot be separated, nor can they separately avail to characterize a true science. But the word "induction" was not pronounced here by chance. The intention was to imply that the aesthetic fact is really nothing but a physical fact, to be studied by the methods proper to the physical and natural sciences.

With such a presupposition and in such a faith did inductive Esthetic or Esthetic from below (what pride in this modesty!) begin its labours. It conscientiously began by making a collection of beautiful things, for example, a great number of envelopes of various shapes and sizes, and asked which of these give the impression of beauty and which of ugliness. As was to be expected, the inductive æstheticians speedily found themselves in a difficulty, for the same objects that appeared ugly in one aspect appeared beautiful in another. A coarse yellow envelope, which would be extremely ugly for the purpose of enclosing a love-letter, is just what is wanted for a writ served by process on stamped paper, which in its turn would look very bad, or seem at any rate an irony, enclosed in a square envelope of English paper. Such considerations of simple common sense should have sufficed to convince inductive æstheticians that the beautiful has no physical existence, and cause them to desist from their vain and ridiculous quest. But no: they had recourse to an expedient, as to which we should hardly like to say how far it belongs to the strict method of natural science. They sent their envelopes round

and opened a referendum, trying to settle in what beauty or ugliness consists by the votes of the majority.

We will not waste time over this subject, lest we should seem to be turning ourselves into tellers of comic tales rather than expositors of æsthetic science and of its problems. It is a matter of fact that the inductive æstheticians have not yet discovered one single law.

He who despairs of doctors is apt to abandon himself to charlatans. This has befallen those who have believed in the naturalistic laws of the beautiful. Artists sometimes adopt empirical canons, such as that of the proportions of the human body, or of the golden section, that is to say, of a line divided into two parts in such a manner that the less is to the greater as is the greater to the whole line (bc ac = ac: ab). Such canons easily become their superstitions, and they attribute to them the success of their works. Thus Michael Angelo left as a precept to his disciple Marco del Pino da Siena that "he should always make a pyramidal serpentine figure multiplied by one two and three," a precept which did not enable Marco da Siena to emerge from that mediocrity which we can yet observe in many of his paintings that exist here in Naples. Others took Michael Angelo's words as authority for the precept that serpentine undulating lines were the true lines of beauty. Whole volumes have been composed on these laws of beauty, on the golden section and on the undulating and serpentine lines. These should in our opinion be looked upon as the astrology of Esthetic.

THE ACTIVITY OF EXTERNALIZATION.

TECHNIQUE AND THE THEORY OF THE ARTS

activity of externalization.

THE fact of the production of physical beauty implies, as The practical has already been remarked, a vigilant will, which persists in not allowing certain visions, intuitions or representations to be lost. Such a will must be able to act with the utmost rapidity and as it were instinctively, and may also need long and laborious deliberations. In any case, thus and thus only does the practical activity enter into relations with the æsthetic, that is to say, no longer as its simple accompaniment, but as a really distinct moment of it. We cannot will or not will our æsthetic vision: we can however will or not will to externalize it, or rather, to preserve and communicate to others, or not, the externalization produced.

tion.

This volitional fact of externalization is preceded by a The technique complex of various kinds of knowledge. These are known of externalizaas technique, like all knowledge which precedes a practical activity. Thus we talk of an artistic technique in the same metaphorical and elliptic manner that we talk of the physically beautiful, that is to say (in more precise language), knowledge at the service of the practical activity directed to producing stimuli to aesthetic reproduction. In place of employing so lengthy a phrase, we shall here avail ourselves of ordinary terminology, whose meaning we now understand.

The possibility of this technical knowledge, at the service of artistic reproduction, is what has led minds astray to imagine the existence of an æsthetic technique of internal expression, which is tantamount to saying, a

doctrine of the means of internal expression, a thing that is altogether inconceivable. And we know well the reason of its inconceivability; expression, considered in itself, is a primary theoretic activity, and as such precedes practice and intellectual knowledge which illumines practice and is independent alike of both. It aids for its part to illumine practice, but is not illuminated by it. Expression does not possess means, because it has not an end; it has intuitions of things, but it does not will and is therefore unanalysable into the abstract components of volition, means and end. Sometimes a certain writer is said to have invented a new technique of fiction or of drama, or a painter is said to have discovered a new technique of distributing light. The word is used here at hazard; because the so-called new technique is really that romance itself, or that new picture itself and nothing else. The distribution of light belongs to the vision of the picture itself; as the technique of a dramatist is his dramatic conception itself. On other occasions, the word "technique" is used to designate certain merits or defects in a work that is a failure; and it is euphemistically said that the conception is bad but the technique good, or that the conception is good but the technique bad.

On the other hand, when we talk of the different ways of painting in oils, or of etching, or of sculpturing in alabaster, then the word "technique" is in its place; but in such a case the adjective "artistic" is used metaphorically. And if a dramatic technique in the æsthetic sense be impossible, a theatrical technique of processes of externalization of certain particular æsthetic works is not impossible. When, for instance, women were introduced on the stage in Italy in the second half of the sixteenth century, in place of men dressed as women, this was a true and real discovery in theatrical technique; such too was the perfecting in the following century of machines for the rapid changing of scenery by the impresarios of Venice.

The collection of technical knowledge at the service of artists desirous of externalizing their expressions, can

theories of the

be divided into groups, which may be entitled theories Technical of the arts. Thus arises a theory of Architecture, com- different arts. prising mechanical laws, information relating to the weight or resistance of the materials of construction or of fortification, manuals relating to the method of mixing lime or stucco; a theory of Sculpture, containing advice as to the instruments to be used for sculpturing the various sorts of stone, for obtaining a successful mixture of bronze, for working with the chisel, for the accurate casting of the clay or plaster model, for keeping clay damp; a theory of Painting, on the various techniques of tempera, of oil-painting, of water-colour, of pastel, on the proportions of the human body, on the laws of perspective; a theory of Oratory, with precepts as to the method of producing, of exercising and of strengthening the voice, of attitude in impersonation and gesture; a theory of Music, on the combinations and fusions of tones and sounds; and so on. Such collections of precepts abound in all literatures. And since it is impossible to say what is useful and what useless to know, books of this sort become very often a sort of encyclopædias or catalogues of desiderata. Vitruvius, in his treatise on Architecture, claims for the architect a knowledge of letters, of drawing, of geometry, of arithmetic, of optic, of history, of natural and moral philosophy, of jurisprudence, of medicine, of astrology, of music, and so on. Everything is worth knowing learn the art and have done with it.

It should be evident that such empirical collections are not reducible to science. They are composed of notions, taken from various sciences and disciplines, and their philosophical and scientific principles are to be found in the latter. To propose to construct a scientific theory of the different arts would be to wish to reduce to the single and homogeneous what is by nature multiple and heterogeneous; to wish to destroy the existence as a collection of what was put together precisely to form a collection. Were we to try to give scientific form to the manuals of the architect, the painter, or the musician, it is clear that nothing would remain in our hands but
