Brilliance –- even genius -- is no guarantee that consequential factors have not been left out or misconceived. Intelligence minus judgment equals intellect. Wisdom is the rarest quality of all–the ability to combine intellect, knowledge, experience, and judgment in a way to produce a coherent understanding…Wisdom requires self-discipline and an understanding of the realities of the world, including the limitations of one’s own experience and of reason itself. The opposite of high intellect is dullness or slowness, but the opposite of wisdom is foolishness, which is far more dangerous.
