“Big words do not smite like war-clubs,
Boastful breath is not a bow-string,
Taunts are not so sharp as arrows,
Deeds are better things than words are,
Actions mightier than boastings.”
Pt. IX.
The Song of Hiawatha (1855)

Context: In private life there are few beings more obnoxious than the man who is always loudly boasting; and if the boaster is not prepared to back up his words his position becomes absolutely contemptible. So it is with the nation. It is both foolish and undignified to indulge in undue self-glorification, and, above all, in loose-tongued denunciation of other peoples. Whenever on any point we come in contact with a foreign power, I hope that we shall always strive to speak courteously and respectfully of that foreign power.

Live longer down the years than deeds.”

Context: My tutor I have already mentioned, Marcus Porcius Cato who was, in his own estimation at least, a living embodiment of that ancient Roman virtue which his ancestors had one after the other shown. He was always boasting of his ancestors, as stupid people do who are aware that they have done nothing themselves to boast about. He boasted particularly of Cato the Censor, who of all characters in Roman history is to me perhaps the most hateful, as having persistently championed the cause of "ancient virtue" and made it identical in the popular mind with churlishness, pedantry and harshness.
