An imaginative system of cosmogony, baseless as the fabric of a dream, is the creation of a moment; to dissipate it the work of ages in study and investigation. Less than a century ago philosophic scepticism could only vent itself in a sneer at the credibility of a tradition, or the fidelity of a manuscript; and the folklore of peasants, encrusted with the hoar of antiquity, was accepted by erudite mystics as the solution of cosmogony and the proof of our communion with the supernatural. An illegible line, a misinterpreted phrase, a suspected interpolation, in some decaying document, the proof or the refutation, was often hailed triumphantly by ardent disputants as announcing the establishment or the overthrow of revelation.
