Famous quotes containing the word merge:
“Popular art is normally decried as vulgar by the cultivated people of its time; then it loses favor with its original audience as a new generation grows up; then it begins to merge into the softer lighting of “quaint,” and cultivated people become interested in it, and finally it begins to take on the archaic dignity of the primitive.”
—Northrop Frye (b. 1912)
