What is wisdom? This is the first in a series of responses to that very question. In this blog, I try to demonstrate that accurately predicting outcomes is a fundamental aspect of wisdom. I bring in both old quotations about wisdom (“From the errors of others, a wise man corrects his own” ~ Publilius Syrus) and new (“Some of the best lessons we ever learn we learn from our mistakes and failures. The error of the past is the wisdom of the future” ~ Tryon Edwards).
