Decorum

Modest Behavior or Decorum.—(a) The Virtue.—The movements and gestures of the body should be regulated by reason, both because they are indications of one’s own character and disposition, and because they express one’s disposition towards those with whom one lives. Hence, they are not a matter of indifference, but reason demands that they be suitable both to oneself (i.e., to one’s sex, age, position, etc.) and to one’s neighbor (i.e., to the requirements of good social usage in each business or affair of life). Thus, virtuous decorum employs both sincerity, which makes one honestly respectful in act (2403), and affability, which makes one agreeable in the company of others (2421). That this is an important virtue for individuals and society is declared both by sacred and human authority. Ecclesiasticus (xix. 26, 27) calls attention to the importance for himself of a man’s looks, laughter and gait; St. Augustine says that there should be nothing offensive to others in one’s movements; and Aristotle mentions among the qualities of the high-minded man that he is sedate and dignified in demeanor.

(b) The Opposite Vices.—Modest behavior is offended by various vices of excess and defect. Thus, sincerity is offended by bluntness and affectation, self-respect by stiffness and servility, and consideration for others by flattery and rudeness.
