In those days, a man at least as boring as I, Pierre Reverdy, was writing: 'The image is a pure creation of the mind. It cannot be born from a comparison but from a juxtaposition of two more or less distant realities. The more the relationship between the two juxtaposed realities is distant and true, the stronger the image will be – the greater its emotional power and poetic reality..' (in the 'Nord-Sud', March 1918). These words, however sibylline for the uninitiated, were extremely revealing, and I pondered them for a long time.
