"Don Quixote made himself ridiculous; but did he know the most tragic ridicule of all, the inward ridicule, the ridiculousness of a man's self to himself, in the eyes of his own soul? Imagine Don Quixote's battlefield to be his own soul; imagine him to be fighting in his soul to save the Middle Ages from the Renaissance, to preserve the treasure of his infancy; imagine him an inward Don Quixote, with a Sancho at his side, inward and heroic too — and tell me if you find anything comic in the tragedy."
