Victor Hugo Quote
Diamonds are found only in the dark bowels of the earth; truths are found only in the depths of thought. It seemed to him that after descending into those depths after long groping in the blackest of this darkness, he had at last found one of these diamonds, one of these truths, and that he held it in his hand; and it blinded him to look at it.
