Origen,
Ante-Nicene Fathers Vol. IV, Origen…
(1885)
“ Strife and prejudice are powerful instruments in leading men to disregard even those things which are abundantly clear; so that they who have somehow become familiar with certain opinions, which have deeply imbued their minds, and stamped them with a certain character, will not give them up. For a man will abandon his habits in respect to other things, although it may be difficult for him to tear himself from them, more easily than he will surrender his opinions. ”
