Seemingly indifferent to pleasure or pain.
The Stoics were members of a philosophical movement
that first appeared in ancient Greece and lasted well into
the Roman era. Stoicism taught that humans should seek
to free themselves from joy, grief, and passions of all kinds
in order to attain wisdom; its teachings thus have much in
common with Buddhism. The great Stoics include the
statesman Cicero, the playwright Seneca, and the emperor
Marcus Aurelius, whose Meditations is the most famous
book of Stoic philosophy. Today we admire the kind of
stoicism that enables some people (who may never have
even heard of Marcus Aurelius) to endure both mental and
physical pain without complaint.
