The apologia for the previous super-controversial Worlds in Collision does away with all literary and mythological evidence and gets down to the bare bones and stones of the earth's history. The contention is boldly, inflexibly, the same; vast global catastrophes, the last of which surely flooded this world a mere few thousands of years before the current era, did the violent work which the Agassiz-Lyell-Darwin hypotheses sought to account for. If the ice Age is not an outright fraud, if uniform change is not the blissful dream of a peace-loving scientist, if evolution is not an outdated euphemism, these concepts are certainly at hopeless odds with the facts adduced by Velikovsky. He cites incredibly large graveyards where no enemy other than global flood could cause such havoc; sand deposits, monster boulders and resurrections of mountains which no known geological forces could have created; remains of an Andean city well developed culturally and of very recent date which was founded so high up that corn will not ripen there. The approach is essentially negative, punching every possible hole in the traditions of geology, paleontology, archaeology, biology, astronomy. The evidence is nevertheless torrential, embracing an immense variety of sources. The tone is often needlessly defiant and antagonistic. But for the science-minded, or even actively curious reader, it is a sensation-monger with a potential perhaps greater than the earlier book.
