Brother André Marie posted the Code of a Gentleman over at his blog. The following is an excerpt:
Without a strict observance of the fundamental Code of Honor [cf., that a gentleman does not lie, cheat, steal, nor tolerate those who do], no man, no matter how ‘polished’, can be considered a gentleman. The honor of a gentleman demands the inviolability of his word, and the incorruptibility of his principles. He is the descendant of the knight, the crusader; he is the defender of the defenseless and the champion of justice… or he is not a Gentleman.
…Does not discuss his family affairs in public or with acquaintances.
…Does not speak more than casually about his girlfriend.
…Does not go to a lady’s house if he is affected by alcohol. He is temperate in the use of alcohol.
…Does not lose his temper; nor exhibit anger, fear, hate, embarrassment, ardor, or hilarity in public...
