She looks unfalteringly on while tortures are being prepared for her; she makes no change of countenance, whether misery or pleasure be offered to her. The wise man therefore can lose nothing of whose loss he will be sensible, for he is the property of virtue alone, from whom he never can be taken away. He enjoys all other things at the good pleasure of Fortune; but who is grieved at the loss of what is not his own? If injury can hurt none of those things which are the peculiar property of the wise man, because while his virtue is safe they are safe, then it is impossible that an injury should be done to a wise man. Demetrius, who was surnamed Poliorcetes, took Megara, and the philosopher Stilbo, when asked by him whether he had lost anything, answered, “No, I carry all my property about me.” Yet his inheritance had been given up to pillage, his daughters had been outraged by the enemy, his country had fallen under a foreign dominion, and it was the king, enthroned on high, surrounded by the spears of his victorious troops, who put this question to him; yet he struck the victory out of the king’s hands, and proved that, though the city was taken, he himself was not only unconquered but unharmed, for he bore with him those true goods which no one can lay hands upon.
