This likewise greatly obstructs the tranquillity of the mind, that our desires are immoderate and not suited to our abilities of attainment, which, like sails beyond the proportion of the vessel, help only to overset it; so that, being blown up with extravagant expectations, if ill success frustrates our attempts, we presently curse our stars and accuse Fortune, when we ought rather to lay the blame upon our enterprising folly.

The partial love of himself is chiefly in fault, which infuseth a vicious inclination to arrogate, and an insatiable ambition to attempt every thing. For they are not content with the affluence of riches and the accomplishments of the mind, that they are robust, have a complaisance of humor and strength of brain for company, that they are privadoes to princes and governors of cities, unless they have dogs of great sagacity and swiftness, horses of a generous strain, nay, unless their quails and cocks are better than other men’s. Old Dionysius, not being satisfied that he was the greatest potentate of his time, grew angry, even to a frenzy, that Philoxenus the poet exceeded him in the sweetness of his voice, and Plato in the subtleties of disputation; therefore he condemned one to the quarries, and sold the other into Aegina. But Alexander was of another temper; for when Criso the famous runner contended with him for swiftness, and seemed to be designedly lagging behind and yielding the race, he was in a great rage with him.
