It is felt that there is something morally wrong with the abstract of reality offered by photography; that one has no right to experience the suffering of others at a distance, denuded of its raw power; that we pay too high a human (or moral) price for those hitherto admired qualities of vision–the standing back from the agressiveness of the world which frees us for observation and for elective attention. But this is only to describe the function of the mind itself.
