"Knowledge comes, but wisdom lingers. It may not be difficult to store up in the mind a vast quantity of face within a comparatively short time, but the ability to form judgments requires the severe discipline of hard work and the tempering heat of experience and maturity"

This quote by Calvin Coolidge talks to the idea that understanding is easy to get, but knowledge is something that takes some time and effort to establish. He recommends that it is simple to learn a lot of details in a short amount of time, however the ability to form sound judgments requires hard work and experience. He suggests that knowledge is something that is earned through dedication and maturity, which it lingers in the mind long after understanding has actually been gotten. This quote motivates us to pursue knowledge, rather than simply understanding, and to acknowledge that wisdom is something that requires time and effort to establish.
