We could do for the classroom of our century what Erasmus did for the classroom of his time. We could make it the matrix of a cultural flowering much greater than that of the Elizabethan Age. For we possess, and to some degree we already experience, the facts of media cross-fertilization. The great eras of culture occur when a large area of oral or auditory experience is invaded by a visual medium. For the Elizabethans the whole folk wisdom of oral culture, centuries of oral disputation, and a huge backlog of vocal music were cross-fertilized by the printed page. A very rich auditory heritage was exposed via a visual medium with spectacular results.
