That we are not totally transformed, that we can turn away, turn the page, switch the channel, does not impugn the ethical value of an assault by images. It is not a defect that we are not seared, that we do not suffer , when we see these images. Neither is the photograph supposed to repair our ignorance about the history and causes of the suffering it picks out and frames. Such images cannot be more than an invitation to pay attention, to reflect, to learn, to examine the rationalizations for mass suffering offered by established powers. Who caused what the picture shows? Who is responsible? Is it excusable? Was it inevitable? Is there some state of affairs which we have accepted up to now that ought to be challenged? All this, with the understanding that moral indignation, like compassion, cannot dictate a course of action.
