The talkative person therefore is merely as regards words a white line,[603] but he that is especially inclined to certain subjects should be especially on his guard against talking about them, and should avoid such topics, since from the pleasure they give him they may entice him to be very prolix and tedious. The same is the case with people in regard to such subjects as they think they are more experienced in and acquainted with than others. For such a one, being self-appreciative and fond of fame, "spends most of the day in that particular branch of study in which he chances to be proficient."[604] Thus he that is fond of reading will give his time to research; the grammarian his to syntax; and the traveller, who has wandered over many countries, his to geography. We must therefore be on our guard against our favourite topics, for they are an enticement to talkativeness, as its wonted haunts are to an animal. Admirable therefore was the behaviour of Cyrus in challenging his companions, not to those contests in which he was superior to them, but to those in which he was inferior, partly that he might not give them pain through his superiority, partly for his own benefit by learning from them. But the talkative person acts just contrary, for if any subject is introduced from which he might learn something he did not know, this he rejects and refuses, not being able to earn a good deal by a short silence,[605] but he rambles round the subject and babbles out stale and commonplace rhapsodies. As one amongst us, who by chance had read two or three of the books of Ephorus,[606] bored everybody, and dispersed every social party, by always narrating the particulars of the battle of Leuctra and its consequences, so that he got nicknamed Epaminondas.
