Moreover, we ought to retire a great deal into ourselves: for association with persons unlike ourselves upsets all that we had arranged, rouses the passions which were at rest, and rubs into a sore any weak or imperfectly healed place in our minds. Nevertheless we ought to mix up these two things, and to pass our lives alternately in solitude and among throngs of people; for the former will make us long for the society of mankind, the latter for that of ourselves, and the one will counteract the other: solitude will cure us when we are sick of crowds, and crowds will cure us when we are sick of solitude. Neither ought we always to keep the mind strained to the same pitch, but it ought sometimes to be relaxed by amusement. Socrates did not blush to play with little boys, Cato used to refresh his mind with wine after he had wearied it with application to affairs of state, and Scipio would move his triumphal and soldierly limbs to the sound of music, not with a feeble and halting gait, as is the fashion nowadays, when we sway in our very walk with more than womanly weakness, but dancing as men were wont in the days of old on sportive and festal occasions, with manly bounds, thinking it no harm to be seen so doing even by their enemies.
