Admit not sleep into your tender eyelids till you have reckoned up each deed of the day—How have I erred, what done of left undone So start, and so review your acts, and then for the vile deeds chide yourself, for the good be glad.

—EpictetusDiscourses, III.10

 

Wonder is the feeling of a philosopher, and philosophy begins in wonder

—Plato Theaetetus, 155
