Even with the advantage of a certain degree of historical perspective,
such as we might expect to enjoy from our standpoint a few decades later, it is by no means easy to define the reasons why late twentieth-century society underwent so violent a process of fragmentation following a relatively long period of consolidation and homogenization. Two factors render the analysis especially difficult: first, the human mind is not particularly well adapted to reconciling information from disparate sources (e.g. personal experience with the content of a school history-lesson, data from a printed page with those from a vuset), and the alleged simplistic linearity of the Gutenberg era — if it ever existed — came to an end before it had affected more than a minuscule proportion of the species; and second, the process is not merely still going on — it’s still accelerating.
“However, one can tentatively point to three major causes which, like tectonic events in the deep strata of the Earth’s crust, not only produce reverberations over enormous areas but actually create discontinuities sharp enough to be uniquely attributed: what one might call psychological landslides.
“By far the most striking of these three is the unforeseen rejection of rationality which has overtaken us. Perhaps one might argue that it was foreshadowed in such phenomena as the adoption by that technically brilliant sub-culture, the Nazis, of Rassenwissenschaft, Hoerbiger’s prescientific Welteislehre, and similar incongruous dogmas. However, it was not until about two generations later that the principle emerged in a fully rounded form, and it became clear that the dearest ambition of a very large number of our species was to abdicate the power of reason altogether: ideally, to enjoy the same kind of life as a laboratory rat with electrodes implanted in the pleasure centers of his brain, gladly starving within reach of food and water.

What third alternative?” Said Chang with the dream-like air of a man who finds himself doing the impossible.
“They gave it to us,” said the Machine.
