Quote by Mortimer J. Adler
There are genuine mysteries in the world that mark the limits of human knowing and thinking. Wisdom is fortified, not destroyed, by understanding its limitations. Ignorance does not make a fool as surely as self-deception.
Summary
This quote emphasizes the existence of certain mysteries or unknowns that exist beyond the realm of human knowledge and comprehension. It suggests that true wisdom comes from acknowledging and accepting these limitations. Rather than being diminished by recognizing what is unknowable, wisdom is strengthened. The quote implies that ignorance alone does not make a person foolish, but self-deception - the act of fooling oneself - is what truly hinders personal growth and understanding.
