What distinguished man from animals was the human capacity for symbolic thought, the capacity which was inseparable from the development of language in which words were not mere signals, but signifiers of something other than themselves. Yet the first symbols were animals. What distinguished men from animals was born of their relationship with them.
John BergerWhen he painted a road, the roadmakers were there in his imagination, when he painted the turned earth of a ploughed field, the gesture of the blade turning the earth was included in his own act. Whenever he looked he saw the labour of existence; and this labour, recognised as such, was what constituted reality for him. (On Vincent Van Gogh)
