Computers may not be able to master poetics like Aristotle, but they have become smart enough to know a metaphor when they see one. An online database called The Mind Is a Metaphor, created by Brad Pasanek, an assistant professor of English at the University of Virginia, is a searchable bank of phrases, verses, and lines from literature that encapsulate metaphors of the mind. Pasanek hopes it will help literary and intellectual historians gain insights into how people's language reflects their understanding of the world around them.
