But even he failed to systematize his thought, and we may say that the true critique of Rhetoric can only be made from the point of view of the aesthetic activity, which is, as we know, _one_, and therefore does not give rise to divisions, and _cannot express the same content now in one form, now in another_. Thus only can we drive away the double monster of naked form deprived of imagination, and of decorated form, which would represent something more than imagination. The same remarks apply to artistic and literary styles, and to their various laws or rules. In modern times they have generally been comprised with rhetoric, and although now discredited, they cannot be said to have altogether disappeared. J.C. Scaliger may be entitled the protagonist of the unities in comparatively modern times: he it was who "laid the foundations of the classical Bastille," and supplied tyrants of literature, like Boileau, with some of their best weapons. Lessing opposed the French rules and restrictions with German rules and restrictions, giving as his opinion that Corneille and others had wrongly interpreted Aristotle, whose rules did not really prevent Shakespeare from being included among correct writers! Lessing undoubtedly believed in intellectual rules for poetry. Aristotle was the tyrant, father of tyrants, and we find Corneille saying "qu'il est aisé de s'accommoder avec Aristote," much in the same way as Tartuffe makes his "accommodements avec le ciel." In the next century, several additions were made to the admitted styles, as for instance the "tragédie bourgeoise." But these battles of the rules with one another are less interesting than the rebellion against all the rules, which began with Pietro Aretino in the sixteenth century, who makes mock of them in the prologues to his comedies. Giordano Bruno took sides against the makers of rules, saying that the rules came from the poetry, and "therefore there are as many genuses and species of true rules as there are genuses and species of true poets." When asked how the true poets are to be known, he replies, "by repeating their verses, which either cause delight, or profit, or both." Guarini, too, said that "the world judges poetry, and its sentence is without appeal."
