The antagonism to Rousseau is so strong that Bonald, for instance, writes page upon page of declamation against the philosopher's appeal to mothers to nurse their children themselves. One would imagine that, in this instance at least, Rousseau's theories would meet with the approval of the stern inculcators of duty. Not at all--the appeal in question shows that Jean-Jacques looked upon human beings as simply animals. "J. J. Rousseau declared in the name of nature that it was the duty of women to suckle their children, exactly as she-animals do, and for the same reason.... Fathers and mothers, regarded by the philosophers as simply males and females, in turn regarded their children simply as their young."[6] And why is Bonald so wrathful? Evidently because he fears that Rousseau may deprive religion of some of its credit by issuing a reasonable commandment not inscribed on the tables of its laws. "Rousseau," he goes on to say, "probably imagined that he had surprised religion in the neglect of a duty; but possibly religion, more far-sighted than he, feared anything which might serve young married people as a reason or excuse for living separated from each other, even momentarily." The motherly solicitude of the Catholic church for the happiness of spouses and the multiplication of the human race--this also is to be placed in the clearest light by means of an attack on Rousseau. We have seen to what misunderstanding of the idea of society the unhistoric, mathematical line of thought of the eighteenth century led. A kindred line of thought produced a very similar misunderstanding of poetry. In their admiration for mathematical reasonableness, and for the certainty with which general truths had been arrived at by mathematical inferences, men were eager to communicate to language, as far as possible, the quality of mathematically exact expression. Condillac defined science as _une langue bien faite, i.e._ a perfectly clear and perfectly exact language. The fact was not sufficiently appreciated that, when it is desired to reproduce impressions which are different in different persons, and which even in the same person may change from one moment to another, a flexible, impressionable language is required, a language which accepts its spirit and whole stamp from the person using it. Scientific men began to deride what they called poetry and style, and maintained that in writing thought was everything, form nothing. Barante, who, in a critical work published at the beginning of the new century, was the first to protest against these ideas of his age, argues cleverly: "When Chimène says to Rodrigue: 'Go! I do not hate thee,' it is plain, if we submit these words to calm investigation, that they mean the same as if she had said: 'Go! I love thee'; and yet, if she used the latter expression, she would be quite a different being; her consideration for her father would be gone, and so would her modesty and her charm."
