Have nothing to do with disreputable occupations and have still less to do with fads that bring more notoriety than good reputation. There are many fanciful sects, and the prudent person flees from them all. There are people with bizarre tastes that always take to heart everything that wise people repudiate. They live in love with eccentricity, and this may make them well known indeed but more as an object of ridicule than of good reputation. A cautious person does not make public his pursuit of wisdom, still less those matters that make him or his followers seem ridiculous. These need not be specified—common contempt has sufficiently singled them out.
