"There are photographic fanatics, just as there are religious fanatics. They buy a so-called candid camera there is no such thing: it’s the photographer who has to be candid, not the camera."

Iconography becomes even more revealing when processes or concepts, rather than objects, must be depicted for the constraint of a definite "thing" cedes directly to the imagination. How can we draw "evolution" or "social organization," not to mention the more mundane "digestion" or "self-interest," without portraying more of a mental structure than a physical reality? If we wish to trace the history of ideas, iconography becomes a candid camera trained upon the scholar's mind.
