There is an advantage to wisdom that comes out of foolishness, that comes when foolishness is shattered, similar to the advantage of light that comes from darkness, that shines when darkness is shattered.
This light is unique in that it can be reached only through darkness.
It may not be greater than other types of light, but it is more precious to a person; it touches on his primal foundations, at the border of light and dark, of being and nonbeing.
—Rabbi Adin Steinsaltz
