Nor are the men of science and technology alone in these views. Sir Herbert Read, the philosopher of art, tells us that we are living through "a revolution so fundamental that we must search many past centuries for a parallel. Possibly the only comparable change is the one that took place between the Old and the New Stone Age ..." And Kurt W. Marek, who under the name C. W. Ceram is best-known as the author of Gods, Graves and Scholars, observes that "we, in the twentieth century, are concluding an era of mankind five thousand years in length ... We are not, as Spengler supposed, in the situation of Rome at the beginning of the Christian West, but in that of the year 3000 B.C. We open our eyes like prehistoric man, we see a world totally new."

One of the most striking statements of this theme has come from Kenneth Boulding, an eminent economist and imaginative social thinker. In justifying his view that the present moment represents a crucial turning point in human history, Boulding observes that "as far as many statistical series related to activities of mankind are concerned, the date that divides human history into two equal parts is well within living memory." In effect, our century represents The Great Median Strip running down the center of human history. Thus he asserts, "The world of today ... is as different from the world in which I was born as that world was from Julius Caesar's. I was born in the middle of human history, to date, roughly. Almost as much has happened since I was born as happened before."

This startling statement can be illustrated in a number of ways. It has been observed, for example, that if the last 50,000 years of man's existence were divided into lifetimes of approximately sixty-two years each, there have been about 800 such lifetimes. Of these 800, fully 650 were spent in caves.
