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

Although widely attributed to Plato, this saying is best read as a modern paraphrase of a Platonic theme: the contrast between ignorance that is understandable (like a child’s fear) and willful resistance to truth. “Dark” stands for the comfort of unexamined belief, while “light” evokes knowledge that can be unsettling because it demands change. The “tragedy” is not simple lack of education but the adult choice to avoid insight—preferring familiar shadows over the moral and intellectual responsibility that comes with seeing clearly. The thought aligns with Plato’s allegory of the cave, where prisoners fear the painful brightness of reality and may reject or attack the one who tries to lead them out.
