Republic 604, B
Plato (427?347 B.C.)
.. OUR1 law surely would say that it is best to keep as tranquil as possible in misfortune, and not to be vexed or resentful: for we cannot see what good or evil there is in such things, and impatience does not in any way help us forwards; also because nothing in human affairs deserves serious anxiety, and grief stands in the way to hinder the self-succour that our duty immediately requires of us.
