We are apt to form romantic and exaggerated notions about the moral innocence of our ancestors. Ages of ignorance and simplicity are thought to be ages of purity. The direct contrary, I believe, is the case... In the middle ages, not only the most flagrant violations of modesty were frequently practised and permitted, but the most infamous vices. Men are less ashamed as they are less polished.
