10. For this χατόρθωμα, which is duty carried out entirely and in perfection, starts from the true source of virtue. Cic. de Off. III. 3, § 13. On this follows another, or ordinary duty. This shows by its name that no hard or extraordinary practice of virtue is involved, for it can be common to very many. The desire to save money is the usual practice with many. To enjoy a well-prepared banquet and a pleasant meal is a general habit; but to fast or to use self-restraint is the practice of but few, and not to be desirous of another’s goods is a virtue rarely found. On the other hand, to wish to deprive another of his property—and not to be content with one’s due—here one will find many to keep company with one. Those (the philosopher would say) are primary duties—these ordinary. Cic. de Off. III. 3, § 14. The primary are found but with few, the ordinary with the many.
