Demetrius, upon the taking of Megara, asked Stilpo, the philosopher, what he had lost. “Nothing,” said he, “for I had all that I could call my own about me.” And yet the enemy had then made himself master of his patrimony, his children, and his country; but these he looked upon as only adventitious goods, and under the command of fortune. Now, he that neither lost any thing nor feared any thing in a public ruin, but was safe and at peace in the middle of the flames, and in the heat of a military intemperance and fury—what violence or provocation imaginable can put such a man as this out of the possession of himself? Walls and castles may be mined and battered, but there is no art or engine that can subvert a steady mind. “I have made my way,” says Stilpo, “through fire and blood—what has become of my children I know not; but these are transitory blessings, and servants that are bound to change their masters; what was my own before is my own still. Some have lost their estates, others their dear-bought mistresses, their commissions and offices: the usurers have lost their bonds and securities: but, Demetrius, for my part I have saved all, and do not imagine after all this, either that Demetrius is a conqueror, or that Stilpo is overcome—it is only thy fortune has been too hard for mine.”
