The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
Daniel J. Boorstin
It is the absence of facts that frightens people: the gap you open, into which they pour their fears, fantasies, desires.
Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours.
No thief, however skillful, can rob one of knowledge, and that is why knowledge is the best and safest treasure to acquire.
L. Frank Baum
Knowledge is a treasure, but practice is the key to it.
I did then what I knew how to do. Now that I know better, I do better.
