Let the man who speaks evil of Alexander not merely bring forward those passages of Alexander’s life which were really evil, but let him collect and review all the actions of Alexander, and then let him thoroughly consider first who and what manner of man he himself is, and what has been his own career; and then let him consider who and what manner of man Alexander was, and to what an eminence of human grandeur he arrived. Let him consider that Alexander was a king, and the undisputed lord of the two continents, and that his name is renowned throughout the whole earth. Let the evil-speaker against Alexander bear all this in mind, and then let him reflect on his own insignificance, the pettiness of his own circumstances and affairs, and the blunders that he makes about these, paltry and trifling as they are. Let him then ask himself whether he is a fit person to censure and revile such a man as Alexander.
