The classical past, for Plutarch, offered a huge reservoir of history, art, and traditions, from which he drew examples of virtue for inspiration and encouragement. He expected that his readers should do the same. But he also insisted that the examples that we draw from that reservoir must be carefully strained and tested, using investigative acumen and skeptical discussion and evaluation, to remove the inevitable debris, the inescapable outcome of human ambition, competition, greed, and desire. Internecine war and personal rivalries polluted those great times even as they did his own day, and still do the present world. The best qualities of the classical past could be reacquired only by the constant exercise of prudent reason and controlled passion. Plutarch dared his readers to accept this challenge.
