Now every medium starts off by exaggerating something that we all have before finally flipping into the opposite of itself. The motorcar flipped into an airplane, but first came the bicycle. The Wright brothers were bicycle men. The gyroscopic principle of the bicycle made possible the airplane. The hula hoop arrived just before the mini-skirt; the hula hoop was a tribal dance which preceded the tribal costume. The effects come first; the cause is later. The laws of the media I simply mention in passing; I could spend a long time on them because they are at least a hope that we can reduce this confusion to some sort of order.
