With the waning of Sir Kenelm Digby's philosophic reputation his name has not become obscure. It stands, vaguely perhaps, but permanently, for something versatile and brilliant and romantic. He remains a perpetual type of the hero of romance, the double hero, in the field of action and the realm of the spirit. Had he lived in an earlier age he would now be a mythological personage; and even without the looming exaggeration and glamour of myth he still imposes. The men of to-day seem all of little stature, and less consequence, beside the gigantic creature who made his way with equal address and audacity in courts and councils, laboratories and ladies' bowers.
