It would, however, be a mistake to suppose that this process is an intensification of modesty. It is, on the contrary, an attenuation of it. The observances of modesty become merely a part of a vast body of rules of social etiquette, though a somewhat stringent part on account of the vague sense still persisting of a deep-lying natural basis. It is a significant coincidence that the eighteenth century, which was marked by this new extension of the social ritual of modesty, also saw the first appearance of a new philosophic impulse not merely to analyze, but to dissolve the conception of modesty. This took place more especially in France. The swift rise to supremacy, during the seventeenth century, of logical and rational methods of thinking, in conjunction with the new development of geometrical and mathematical science, led in the eighteenth century to a widespread belief in France that human customs and human society ought to be founded on a strictly logical and rational basis. It was a belief which ignored those legitimate claims of the emotional nature which the nineteenth century afterwards investigated and developed, but it was of immense service to mankind in clearing away useless prejudices and superstitions, and it culminated in the reforms of the great Revolution which most other nations have since been painfully struggling to attain. Modesty offered a tempting field for the eighteenth century philosophic spirit to explore. The manner in which the most distinguished and adventurous minds of the century approached it, can scarcely be better illustrated than by a conversation, reported by Madame d'Epinay, which took place in 1750 at the table of Mlle. Quinault, the eminent actress. "A fine virtue," Duclos remarked, "which one fastens on in the morning with pins." He proceeded to argue that "a moral law must hold good always and everywhere, which modesty does not." Saint-Lambert, the poet, observed that "it must be acknowledged that one can say nothing good about innocence without being a little corrupted," and Duclos added "or of modesty without being impudent." Saint-Lambert finally held forth with much poetic enthusiasm concerning the desirability of consummating marriages in public.[59] This view of modesty, combined with the introduction of Greek fashions, gained ground to such an extent that towards the end of the century women, to the detriment of their health, were sometimes content to dress in transparent gauze, and even to walk abroad in the Champs Elysées without any clothing; that, however, was too much for the public.[60] The final outcome of the eighteenth century spirit in this direction was, as we know, by no means the dissolution of modesty. But it led to a clearer realization of what is permanent in its organic foundations and what is merely temporary in its shifting manifestations. That is a realization which is no mean task to achieve, and is difficult for many, even yet. So intelligent a traveler as Mrs.
