If a person were to try stripping the disguises from actors while they play a scene upon stage, showing to the audience their real looks and the faces they were born with, would not such a one spoil the whole play ? And would not the spectators think he deserved to be driven out of the theatre with brickbats, as a drunken disturber ?... Now what else is the whole life of mortals but a sort of comedy, in which the various actors, disguised by various costumes and masks, walk on and play each one his part, until the manager waves them off the stage ? Moreover, this manager frequently bids the same actor to go back in a different costume, so that he who has but lately played the king in scarlet now acts the flunkey in patched clothes. Thus all things are presented by shadows.
