In proclaiming this, their-adversaries, the relativists, are perfectly right, and effect an advance upon them. However, the initial rationality of their thesis in its turn becomes converted into a false theory. Repeating the ancient adage that there is no accounting for tastes, they believe that æsthetic expression is of the same nature as the pleasant and the unpleasant, which every one feels in his own way, and about which there is no dispute. But we know that the pleasant and the unpleasant are utilitarian, practical facts. Thus the relativists deny the specific character of the æsthetic fact, and again confound expression with impression, the theoretic with the practical.

The true solution lies in rejecting alike relativism or psychologism and false absolutism; and in recognizing that the criterion of taste is absolute, but absolute in a different way from that of the intellect, which expresses itself in ratiocination. The criterion of taste is absolute, with the intuitive absoluteness of the imagination. Thus any act of expressive activity, which is so really, is to be recognized as beautiful, and any fact as ugly in which expressive activity and passivity are found engaged with one another in an unfinished struggle.

Criticism of relative relativism.

Between absolutists and relativists is a third class, which may be called that of the relative relativists. These affirm the existence of absolute values in other fields, such as Logic and Ethic, but deny it in the field of Æsthetic. To dispute about science or morals seems to them to be rational and justifiable, because science depends upon the universal, common to all men, and morality upon duty, which is also a law of human nature; but how dispute about art, which depends upon imagination? Not only, however, is the imaginative activity universal and no less inherent in human nature than the logical concept and practical duty; but there is a preliminary objection to the thesis in question. If the absoluteness of the imagination be denied, we must also deny intellectual or conceptual truth and implicitly morality. Does not morality presuppose logical distinctions? How could these be known, otherwise than in expressions and words, that is to say, in imaginative form? If the absoluteness of the imagination were removed, the life of the spirit would tremble to its foundations. One individual would no longer understand another, nor indeed his own self of a moment before, which is already another individual considered a moment after.

Objection founded on the variation of the stimulus and of psychic disposition.

Nevertheless, variety of judgements is an indubitable fact. Men disagree as to logical, ethical, and economical valuations; and they disagree equally or even more as to the æsthetic. If certain reasons recorded by us above, such as haste, prejudices, passions, etc., may lessen the importance of this disagreement, they do not on that account annul it. When speaking of the stimuli of reproduction we have added a caution, for we said that reproduction takes place, if all the other conditions remain equal. Do they remain equal? Does the hypothesis correspond to reality?

It would appear not. In order to reproduce an impression several times by means of a suitable physical stimulus it is necessary that this stimulus be not changed, and that the organism remain in the same psychical conditions as those in which was experienced the impression that it is desired to reproduce. Now it is a fact that the physical stimulus is continually changing, and in like manner the psychological conditions.

Oil-paintings grow dark, frescoes fade, statues lose noses, hands and legs, architecture becomes totally or partially a ruin, the tradition of the execution of a piece of music is lost, the text of a poem is corrupted by bad copyists or bad printing. These are obvious instances of I the changes which daily occur in objects or physical stimuli. As regards psychological conditions, we will not dwell upon the cases of deafness or blindness, that is to say, upon the loss of entire orders of psychical impressions; these cases are secondary and of less importance compared with the fundamental, daily, inevitable and perpetual changes of the society around us and of the internal conditions of our individual life. The phonetic manifestations or words and verses of Dante's Commedia must produce a very different impression on an Italian citizen engaged in the politics of the third Rome, from that experienced by a well-informed and intimate contemporary of the poet. The Madonna of Cimabue is still in the Church of Santa Maria Novella; but does she speak to the visitor of to-day as to the Florentines of the thirteenth century? Even though she were not also darkened by time, must we not suppose that the impression which she now produces is altogether different from that of former times? And even in the case of the same individual poet, will a poem composed by him in youth make the same impression upon him when he re-reads it in his old age, with psychic conditions altogether changed?

Criticism of the distinction of signs into natural and conventional.

It is true that certain æstheticians have attempted a distinction between stimuli and stimuli, between natural and conventional signs. The former are held to have a constant effect upon all; the latter only upon a limited circle. In their belief, signs employed in painting are natural, those used in poetry conventional. But the difference between them is at the most only one of degree. It has often been said that painting is a language understood by all, while with poetry it is otherwise. Here, for example, Leonardo found one of the prerogatives of his art, "which hath not need of interpreters of different tongues as have letters," and it pleases man and beast. He relates the anecdote of that portrait of the father of a family "which the little grandchildren were wont to caress while they were still in swaddling-clothes, and the dogs and cats of the house in like manner." But other anecdotes, such as those of the savages who took the portrait of a soldier for a boat, or considered the portrait of a man on horseback to be furnished with only one leg, are apt to shake one's faith in the understanding of painting by sucklings, dogs and cats. Fortunately, no arduous researches are necessary to convince oneself that pictures, poetry and all works of art only produce effects upon souls prepared to receive them. Natural signs do not exist; because all are equally conventional, or, to speak with greater exactness, historically conditioned.
