Knowledge is information that has been integrated into the mind, memory and body, such that it can be applied to doing and making things, also called “know-how.” Knowledge is usually acquired through experience, or through stories about other people’s experiences.
Wisdom is the ability to perceive value, make judgments, and evaluate long-term consequences. Russell Ackoff describes the difference between knowledge and wisdom as the difference between doing things right and doing the right thing. Wisdom requires values, and values are perhaps the most relative thing of all.
