Ancient & Medieval Philosophy -- David L. Rouse
Their persuasions by means of fictions are innumerable; for if everyone had recollection of the past, knowledge of the present, and foreknowledge of the future, the power of speech would not be so great. But as it is, when men can neither remember the past nor observe the present nor prophesy the future, deception is easy; so that most men offer opinion as advice to the soul. But opinion, being unreliable, involves those who accept it in equally uncertain fortunes.
Thus, persuasion by speech is equivalent to abduction by force, as she was compelled to agree to what was said, and consent to what was done. It was therefore the persuader, not Helen, who did wrong and should be blamed.
