Full Idea
A teacher is incapable of doing anything of his own for his own good. He always thinks of the good of his pupils, and all new knowledge gladdens him only to the extent that he can teach it. He is a thoroughfare for learning, and has lost seriousness.
Gist of Idea
Teachers only gather knowledge for their pupils, and can't be serious about themselves

A Reaction
Oh dear. I look in the mirror. Do I only delight in finding all these quotations so that I can stick them in the database and pass them on to someone else? Are they actually impingeing on my life? Could I meet an idea that made me abandon this project?
