“Tell me and I forget, teach me and I may remember, involve me and I learn.”
-The Internet, although often attributed to Benjamin Franklin or Confucius.
Quote Investigator is fairly certain original credit goes to Xunzi (Xun Kuang), a Confucian philosopher who lived in the third century B.C.E., with the quote:
“Not having heard of it is not as good as having heard of it. Having heard of it is not as good as having seen it. Having seen it is not as good as knowing it. Knowing it is not as good as putting it into practice. Learning arrives at putting it into practice and then stops . . .”
