The Power of the Image

Emotion, Expression, Explanation

We think primarily in images, and only secondarily in words, while both the image and the word are preceded by the bodily, the visceral, the muscular. This holds even for mathematical thinking. It is the entire motor system, including facial expressions and bodily gestures, that underlies not just emotions but also abstract thought. Communication, too, is a primordially visual task, spoken and written language only gradually supplementing and even supplanting the pictorial. Writing liberates, but also enslaves; after centuries of a dominantly verbal culture, today the ease of producing and accessing digital images amounts to a homecoming of the visual, with the almost limitless online availability of our textual heritage completing the educational revolution of the 21st century.
