Also, Philo doesn't directly compare the Therapeutae to the Essenes. I can discover no statement of Therapeutae pacifism. Quite the contrary, Philo implicitly acknowledges their willingness to defend themselves by force.
Subtle polemics are pervasive throughout.
They apparently preferred poverty, hunger, isolation and the abandonment of all their worldly possessions to the very real dangers of city life. The Therapeutae were clearly concerned with being attacked, robbed and slain in a repeat of the earlier pogroms their life of isolation was necessitated by the grievous violence they had come to expect from the cities. Philo are just brilliant.
