Darkness and Light

"We can easily forgive a child who is afraid of the dark; the real tragedy if life is when men are afreaid of the light."

This quote by Plato struck me. It made me think of the allegory of the cave, in which those born in darkness do not trust the reality of the light. Also, the use of the word tragedy was itnersting to me, seeing as how in class we have spoken of the definition of what the supreme tragedy is.
