Summary:
Yuval Noah Harari’s best-selling book “Sapiens” is subtitled
“A Brief History of Humankind.” While
this may seem to bespeak a bit of hubris—it would seem that 414 pages might be,
despite the modifying adjective of the subtitle, a little too condensed to cover
2.5 million years (albeit only the last 70,000 or so in any kind of detail)—the
impression after finishing is that he may have done it, or at least, done the
effort proud. Mustering a combination of
data and insights from the domains of history, archeology, genetics, biology,
paleobiology, economics, and sociology, among others, Harari weaves an
organized narrative that attempts to answer the questions of who we are and how
we got here.
He divides the story into four assigned landmark periods in
human history: The Cognitive Revolution
(the earliest organization of humans into groups which evidence the use of
tools and the beginnings of culture), The Agricultural Revolution (the impact
of the learned ability to cultivate the land, with its shift from hunters and
gatherers to farmers, and by necessity, from nomadic to settled tribes, and the
beginnings of towns), The Unification of Humankind (the aggregation of people
into larger groups and the emergence of money (and the earliest capitalism),
religion, social expansion and conquest), and The Scientific Revolution (the development
of science and the incredibly rapid acceleration of knowledge in the last five
or six hundred years). The titles of the
periods are, however, only guideposts, for the sections are broader in scope
than simply farming or science. The
section on the scientific revolution, for example, interweaves scientific
progress with economics and imperialism (which are themselves interwoven, after
all), religion, and philosophy. And that
same section leads Harari to speculate, at the end, as to where the digital revolution
and the development of artificial intelligence might be leading us and what we
might say about our future as a species.
