"This inhumanity of mercenary commerce is the more notable because it is a fulfilment of the law that the corruption of the best is the worst. … And this is the ultimate lesson which the leader of English intellect meant for us … in the tale of the "Merchant of Venice"; in which the true and incorrupt merchant,—kind and free, beyond every other Shakespearian conception of men,—is opposed to the corrupted merchant, or usurer; the lesson being deepened by the expression of the strange hatred which the corrupted merchant bears to the pure one, mixed with intense scorn."
