History is an account, mostly false, of events, mostly unimportant, which are brought about by rulers, mostly knaves, and soldiers, mostly fools.
Ambrose Bierce
truisms
Wherefore on no account suffer any evil habit to master thee; but, while it is yet young, pluck the evil root out of thine heart, lest it fasten on and strike root so deep that time and labor be required to uproot it. And the reason that greater sins assault us and get the mastery of our souls is that those which appear to be less, such as wicked thoughts, unseemly words and evil communications, fail to receive proper correction.
St. John Damascene, Barlaam and Ioasaph
"The devil does not hunt after those who are lost; he hunts after those who are aware, those who are close to God. He takes from them trust in God and begins to afflict them with self-assurance, logic, thinking, criticism. Therefore we should not trust our logical minds. Never believe your thoughts."
Elder Paisios
