" 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 in the Dies Iræ:
Recordare, Jesu pie,
Quod sum causa tuæ viæ.
Ne me perdas illa die.
Pray remember, sacred Savior,
Whose the thoughtless hand that gave your
Death-blow. Pardon such behavior. "
― Ambrose Bierce , The Unabridged Devil's Dictionary
