A symbol loses its magical or, if you prefer, its redeeming power as soon as its liability to dissolve is recognized. To be effective, a symbol must be by its very nature unassailable. It must be the best possible expression of the prevailing world-view, an unsurpassed container of meaning; it must also be sufficiently remote from comprehension to resist all attempts of the critical intellect to break it down; and finally, its aesthetic form must appeal so convincingly to our feelings that no argument can be raised against it on that score.
