How shall a man go through college without having been marked for taste and judgment? What will become of him? What will his end be? He will have to take continuation courses for college graduates. He will have to go to night schools. They are having night schools now, you know, for college graduates. Why? Because they have not been educated enough to find their way around in contemporary literature. They don’t know what they may safely like in the libraries and galleries. They don’t know how to judge an editorial when they see one. They don’t know how to judge a political campaign. They don’t know when they are being fooled by a metaphor, an analogy, a parable. And metaphor is, of course, what we are talking about. Education by poetry is education by metaphor.
Robert Frost, Education by Poetry
