"Ceci n'est pas une pipe." Belgian surrealist Rene Magritte with his iconic painting of what seems the perfection of a pipe makes a valid point: Even the most authentic rendition of a natural object i s n' t that object. It remains an image of it.
Why does that matter?
Because these days, images define how we view the world.
Think of the iconic image of President Trump at the G7 meeting in Canada. It pits the three European leaders Merkel, May and Macron against a US President, whose body language encapsulates everything that went wrong at this G7 summit: A US President isolated, sitting apart, arms crossed, stubborn, pouting. Multilateralism hits rock bottom.
