The decay of authority is one of the most marked features of our time. Religion, politics, art, manners, speech, even morality, considered in its widest sense, have all felt the waning of traditional authority, and the substitution for it of individual opinion and taste, and of the wavering and contradictory utterances of publications ostensibly occupied with criticism and supposed to be pronouncing serious judgments. By authority I do not mean the delivery of dogmatic decisions, analogous to those issued by a legal tribunal from which there is no appeal, that have to be accepted and obeyed, but the existence of a body of opinion of long standing, arrived at after due investigation and experience during many generations, and reposing on fixed principles or fundamentals of thought.
