Cogito, Ergo Sum
The Life of Rene Descartes
RENE DESCARTES is the philosophical architect
of our modern world. In metaphysics, he estab-
lished the view that mind and body are distinct
substances, a position foundational for any belief
that the human soul is immortal. In mathemat-
ics, he invented analytic geometry — the basis of
calculus — which makes physics as we know it
possible. Descartes perfected the method of pro-
posing and testing hypotheses with experiments
that anyone can repeat, which forms the basis of
modern science. In optics, he discovered and
described laws of refraction and reflection. In
medicine, he was a pioneer in vivisection and
anatomical description for understanding the
human body. In physiology, his analysis of the
relations among the sense organs, nerves, and the
brain is still taught today. In psychology, he dis-
covered conditioned reflexes and investigated the
role of the emotions in human behavior. Des-
cartes said there was no point in trying to refute
Aristotelian Scholasticism; rather, he would sim-
ply show a better way. Some 350 years after his
death, our twenty-first-century world — from
mind-body dualism to heart pumps, from pop
psychology to personal computers — is thor-
oughly Cartesian. Nothing in the modern world
would alarm or surprise him were he alive today.
Descartes’s motto was that a life well hidden is
a life well lived. Much of his own life is obscure to
us now, which has led to tales of the great philoso-
pher lying in bed meditating each morning until
eleven, piously following the dictates of a cardinal,
writing verses for a queen, and so on. Many of
these myths are exploded in Cogito, Ergo Sum, the
