Depth awareness is created by parallel suggestion, not by connected statement. Yeats´s observation [regarding “emotion of multitude”] can also be found in Bacon, who writes on the modes of aphorism as contrasted with "writing in Method," in his Advancement of Learning: "Aphorisms, representing a knowledge broken, do invite men to inquire farther; whereas Methods, carrying the show of a total, do secure men, as if they were at farthest." Even the ad agencies know that to sell a car or a coat they must present the satisfactions in figure-ground relationship that will create the desired psychic effects.
