Marcus Aurelius, for one (5)

I believe the answer is:

stoic

(Other definitions for stoic that I've seen before include "Someone seemingly indifferent to pleasure or pain" , "Uncomplaining person" , "Long-suffering type; follower of Zeno" , "not given to complaining" , "the original Zeno?" .)

I've seen this clue in the LA Times.
