[Sidenote: His ethical views.] On the passions which move men and make history he seems to have thought much like other people. He knew that avarice is the cause of many crimes, and that love is the source both of great happiness and of great misery. Yet he appears to have held that the mischief wrought by the passion of love outweighs the good it brings; for after telling how, by washing in the river Selemnus, men and women were supposed to forget their love, he adds that if there is any truth in this story great riches are less precious to mankind than the water of the Selemnus. Again, he has a sincere admiration for the heroic virtues, and a genuine detestation of baseness and depravity of all sorts. Treason he stigmatises as the foulest of crimes. He considers that the bold and disinterested patriot Thrasybulus, who freed his country and healed her dissensions, was the best of all the famous men of Athens, and that the deed of Leonidas and his Spartans at Thermopylae was the most splendid feat of arms in Grecian history. He praises his Spartan namesake for his courteous treatment of the captive Coan lady and for rejecting the base proposal of the wretch who would have had him mutilate the corpse of the gallant Mardonius. He speaks with sympathy of the brave men worthy of a happier fate who fell on the tyrant Lachares, of those who would have wrested Piraeus from the Macedonians had they not been done by their confederates to death, and of those others whom on the great day Cimon led to victory by sea and land. He tells how in the last fight with the Romans, before the day was lost, the Achaean general fled, leaving his men to shift for themselves, and he contrasts his selfish cowardice with the soldierly devotion of an Athenian cavalry officer who on the disastrous retreat from Syracuse brought off his regiment safe, then wheeled about and, riding back alone, found the death he sought in the midst of the enemy.
