“Letter 101 Rica to the Same I told you the other day of the extra-ordinary inconstancy of the French in their fashions. Yet it is inconceivable to what an extent they are infatuated about them; everything is swayed by them: fashion is the rule by which they judge what is done in other nations; whatever is foreign always seems to them ridiculous. I confess that I hardly know how to reconcile this bigoted devotion to their customs with the inconstancy which changes them every day. When I say that they despise everything foreign, I mean only trifles;” source
