Full Idea
It is not the man who thinks he knows it all, that can bring other men to feel their need for learning, and it is only a deep sense that one is miserably ignorant that can spur one on in the toilsome path of learning.
Gist of Idea
We are not inspired by other people's knowledge; a sense of our ignorance motivates study
