Ammianus Marcellinus

No wild beasts are so deadly to humans as most Christians are to each other.

Anger is defined by philosophers as a long-standing and sometimes incurable mental ulcer, usually arising from weakness of intellect. In support of this they argue with some plausibility that this tendency occurs more in invalids than in the healthy, more in women than in men, more in the old than the young, more in those in trouble than in the prosperous.
