Newton, Descartes, Galileo, and the Enlightenment
Very briefly, they advocated the notion that the natural world (which they regarded
as a distal manifestation of the power of their deity) could be understood by rational and
experimental means. This was in considerable contrast to the then-prevailing Western view
that all natural phenomena were proximal manifestations of the deity and could only be
understood, if at all, by mystical and spiritual means. They had some remarkable company
for this view, which begins in late medieval times and continues into the Renaissance:
Roger Bacon, Desiderius Erasmus, Leonardo daVinci and Galileo Galilei. But Galileo, Descartes, and
Newton showed most convincingly the feasibility of this idea by doing it: and their
work, together with that of thousands of scientists, writers, explorers, philosophers,
engineers, artists, and musicians, coalesced into a new way of looking at the universe we
now call the Enlightenment. Any intellectual history will treat this topic: one could do
worse than start with
Boorstin
,
which treats mostly Western scientific history.
