Honorable, adj.: Afflicted with an impediment in one's reach. In legislative bodies, it is customary to mention all members as honorable; as, "the honorable gentleman is a scurvy cur.".
I never cheat or steal. Also, I never wear a top-hat with a sack coat or munch bananas in public on the streets, because a gentleman does not do those things either. I would as soon do the one as the other sort of thing--it is all a matter of harmony and good taste.
As a general rule, do not kick the shins of the opposite gentleman under the table, if personally unaquainted with him; your pleasantry is liable to be misunderstood--a circumstance at all times unpleasant.
The Master said, “A true gentleman is one who has set his heart upon the Way. A fellow who is ashamed merely of shabby clothing or modest meals is not even worth conversing with.” (Analects 4.9)
The gentleman is a man of truth, lord of his own actions, and expressing that lordship in his behavior, not in any manner dependent and servile either on persons, or opinions, or possessions.
