BEHAVIOR, n.
Conduct, as determined, not by principle, but by breeding. The word seems to be somewhat loosely used in Dr. Jamrach Holobom's translation of the following lines from the _Dies Irae_:
Recordare, Jesu pie, Quod sum causa tuae viae. Ne me perdas illa die.
Pray remember, sacred Savior, Whose the thoughtless hand that gave your Death-blow. Pardon such behavior.
--Ambrose Bierce - The Devil's Dictionary
