hearts are as open as faces; in manners, in virtue, even in vice, one detects always a certain artlessness.

Context

“in that slavery of heart and mind, it is only fear that utters a dull routine of words, very different from the language of nature which expresses itself so variously. Dissimulation, that art so practised and so necessary with us, is here unknown: they say everything, see everything, and hear everything; hearts are as open as faces; in manners, in virtue, even in vice, one detects always a certain artlessness. In order to gratify women a talent is necessary different from that other gift which pleases them still more; it consists in a sort of playfulness of mind, which entertains them, as it seems to promise them every moment what one cannot perform except occasionally.” source
