"The wise man conceals his intelligence; the fool displays his foolishness."- Yiddish Proverb
What does it really mean to know something? We are always looking for more data, more information. And how often it seems like we cling to our assumptions as if they are Torah from Sinai, when really we're exercising our own egos (this happens a lot on the internet).
Rabbi Ed Friedman wrote that, "The great lesson... for all imaginatively gridlocked systems is that the acceptance and even cherishing of uncertainty is critical to keeping the human mind from voyaging into the delusion of omniscience." Ambiguity, uncertainty, and humility should guide and inform our behavior, rather than false knowing. In this way may we he wise rather than foolish.
