*132* Motus autem animorum duplices sunt, alteri cogitationis, alteri appetitus; cogitatio in vero exquirendo maxime versatur, appetitus impellit ad agendum. Curandum est igitur, ut cogitatione ad res quam optimas utamur, appetitum rationi oboedientem praebeamus. [129] _ineptiis non vacant_ A B H a b; _inepti non vacant offensione_ L c p.

Again, there are two orders of beauty: in the one, loveliness predominates; in the other, dignity; of these, we ought to regard loveliness as the attribute of woman, and dignity as the attribute of man. Therefore, let all finery not suitable to a man's dignity be kept off his person, and let him guard against the like fault in gesture and action. The manners taught in the palaestra,[AC] for example, are often rather objectionable, and the gestures of actors on the stage are not always free from affectation; but simple, unaffected manners are commendable in both instances. Now dignity of mien is also to be enhanced by a good complexion; the complexion is the result of physical exercise. We must besides present an appearance of neatness--not too punctilious or exquisite, but just enough to avoid boorish and ill-bred slovenliness. We must follow the same principle in regard to dress. In this, as in most things, the best rule is the golden mean. #(2) in inward self-control.# *131* We must be careful, too, not to fall into a habit of listless sauntering in our gait, so as to look like carriers in festal processions, or of hurrying too fast, when time presses. If we do this, it puts us out of breath, our looks are changed, our features distorted; and all this is clear evidence of a lack of poise. But it is much more important that we succeed in keeping our mental operations in harmony with nature's laws. And we shall not fail in this if we guard against violent excitement or depression, and if we keep our minds intent on the observance of propriety. *132* Our mental operations, moreover, are of two kinds: some have to do with thought, others with impulse. Thought is occupied chiefly with the discovery of truth; impulse prompts to action. We must be careful, therefore, to employ our thoughts on themes as elevating as possible and to keep our impulses under the control of reason. [AC] The Greek palaestra, a public school of wrestling and athletics, adopted by the Romans became a place of exercise where the youth were trained in gestures and attitudes, a nursery of foppish manners.
