【正文】 and virtue was never so beholding to human nature, as it received his due at the second hand. Neither had the fame of Cicero, Seneca, Plinius Secundus, borne her age so well, if it had not been joined with some vanity in themselves: like unto varnish, that makes sealings not only shine, but last But all this while, when I speak of vainglory, I mean not of that property, that Tacitus doth attribute to Mucianus。 and those mat are of solid and sober natures have more of the ballast, than of the sail. In fame of learning, the flight w ill be slow, without some feathers of ostentation. Q ui de contenm enda gloria libros scribunt, nomen suum inscribunt. Socrates, Aristotle, Galen, were men firil of ostentation. Certainly vainglory helpeth to perpetuate a man\39。 as if a man that negotiates between two princes, to draw them to join in a war against the third, doth extol the forces of either of them above measure, the one to the other: and sometimes, he that deals between man and man, raiseth his own credit with both by pretending greater interest than he hath in either. And in these, and the like kinds, it often falls out that somew hat is produced of nothing: for lies are sufficient to breed opinion, and opinion brings on substance. In military manders and soldiers, vainglory is an essential point。 beaucoup de bruit, peu de fruit: much bruit, little fruit Yet certainly there is use of this quality, in civil affairs. Where there is an opinion, and fame to be created, either of virtue, or greatness, these men are good trumpeters. Again, as Titus Livius noteth, in the case of Antiochus, and the Aetolians。 for all bravery stands upon parisons. They must needs be violent, to make good their own vaunts. Neither can they be secret, and therefore not effectual。 but we have a wild journey, also which is national and modern, and that is the journey to Amack on the night of the New Year. All indifferent poets and poetesses, musicians, newspaper writers, and artistic notabilities, I mean those who are no good, ride in the New Year39。t know what that is! The journey of the witches on broomsticks is well enough known that journey is taken on St. John39。s eve I was reading the book, and had lost myself in it so pletely, that I fot my usual New Year39。 the fly sat upon the axletree of the chariot wheel, and said.
