A photograph never stands alone: Teju Cole

'All images, regardless of the date of their creation, exist simultaneously and are pressed into service to help us make sense of other images. This suggests a possible approach to photography criticism: a river of interconnected images wordlessly but fluently commenting on one another.'

'A photograph can’t help taming what it shows. We are accustomed to speaking about photographs as though they were identical to their subject matter. But photographs are also pictures — organized forms on a two-dimensional surface — and they are part of the history of pictures. A picture of something terrible will always be caught between two worlds: the world of “something terrible,” which might shock us or move us to a moral response, and the world of “a picture,” which generates an aesthetic response. The dazzle of art and the bitterness of life are yoked to each other. There is no escape.'
