The feeling of this age of ours, of this our moment in eternity, is different in its conception of life from that of our ancestors. Only eternal earth has changed not nor grown older, that field, gloomed by the Unknown, on which the monotonous light of the seasons divides, in a rhythmic round, the time of blossoms and of their withering; changeless only are the action of the elements and the restless alternation of night and day.
