“The capacity to grasp and manipulate complex ideas is enough to define intellect, but not enough to encompass intelligence, which involves combining intellect with judgment and care in selecting relevant, explanatory factors and in establishing empirical tests of any theory that emerges. 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 is the fulfillment of the ancient admonition, “With all your getting, get understanding.” Wisdom requires self-discipline and an understanding of the realities of the world, including the limitation of one’s own experience and of reason itself. The opposite of intellect is dullness or slowness, but the opposite of wisdom is foolishness, which is far more dangerous.”
