Wisdom is a deep understanding of people, things, events or situations, empowering the ability to choose or act to consistently produce the optimum results with a minimum of time and energy. Wisdom is the ability to optimally (effectively and efficiently) apply perceptions and knowledge and so produce the desired results. Wisdom is comprehension of what is true or right coupled with optimum judgment as to action. Synonums include: sagacity, discernment, or insight. Wisdom often requires control of one's emotional reactions (the "passions") so that one's principles, reason and knowledge prevail to determine one's actions.
