The data for political studies are most commonly drawn from history, either in accounts of lives, events and institutions, or in the writings of earlier systematic students. But to probe the meaning and relationships of ultimate ends like justice and truth, no actual happenings are needed; imaginative fiction and drama can supply the food for thought. Why then should we not as reasonably and profitably look for lessons in political wisdom in the works of our greatest poet? In this essay I have sought to find and expound such a lesson in Shakespeare's tragedy, King Lear.
According to that profound student of Shakespeare, Abraham Lincoln, the most difficult task of statesmanship is that of providing, not for the foundation, but for the perpetuation, of political institutions. If the political institutions are the best, to perpetuate them is not only the most difficult, but also the greatest of all the tasks of the statesman.
