couldn't have put Humpty-Dumpty back together. The integral and unified egg had no business sitting on a wall, anyway. Walls are made of uniformly fragmented bricks that arise with specialisms and bureaucracies. They are the deadly enemies of integral beings like eggs. Humpty-Dumpty met the challenge of the wall with a spectacular collapse. The same nursery rhyme comments on the consequences of the fall of Humpty-Dumpty. That is the point about the King's horses and men. They, too, are fragmented and specialized. Having no unified vision of the whole, they are helpless. Humpty-Dumpty is an obvious example of integral wholeness. The mere existence of the wall already spelt his fall. James Joyce in Finnegans Wake never ceases to interlace these themes, and the title of the work indicates his awareness that "a stone-aging" as it may be, the electric age is recovering the unity of plastic and iconic space, and is putting Humpty-Dumpty back together again. The potter’s wheel, like all other technologies, was the acceleration of an existing process. After nomad food-gathering had shifted to sedentary plowing and seeding, the need for storage increased. Pots were needed for more and more purposes. Men turned their powers to changing the forms of things by cultivation. Change to special production in local areas created the need for exchange and for transport. For this purpose sledges were used in Northern Europe before 5000 B.C., and human porters and pack-bearing animals preceded sledges naturally. The wheel under the sledge was an accelerator of feet, not of hand. With this acceleration of the feet came the need for road, just as with the extension of our backsides in the form of chair, came the need for table. The wheel is an ablative absolute of feet, as chair is the ablative absolute of backside. But when such ablatives intrude, they alter the syntax of society. There is no ceteris paribus in the world of media and technology. Every extension or acceleration effects new configurations in the over-all situation at once.
