I just ran across this quote from Minor White:

"Art traditionally claims a concern with man's pure impulses and clean motives, yet many a contemporary psychologist thinks that all this is pure hokum. So do some photographers. And in protest and in truth, in soul searching and awareness of our self-destroying age, many people in contemporary art, notably Frederick Sommer in contemporary photography, present images which are intended in such a particular way that if the viewer engages the images at all, then the viewer will see something of himself. If what he sees is unpleasant, that there may be some truth in that some part of himself is unpleasant—if dirty, morbid and so onà If he is struck with terror, perhaps he has met something worthy of his fear. If he finds something magnificent, it is because something beautiful in him has been magnified."
