W.J.T. Mitchell said: "Mental imagery belongs to psychology and epistemology; optical imagery to physics; graphic, sculptural, and architectural imagery to the art historian; verbal imagery to the literary critic; perceptual images occupy a kind of border region where physiologists, neurologists, psychologists, art historians, and students of optics find themselves collaborating with philosophers and literary critics."

The mutual call between verbs and images may be a way to activate perception and make us reflect on the unspeakable and unseen world.
