"The ultimate wisdom of the photographic image is to say, 'There is the surface. Now think - or rather feel, intuit - what is beyond it, what the reality must be like if it looks that way.' Photographs, which cannot themselves explain anything, are inexhaustible invitations to deduction, speculation, and fantasy . . . The very muteness of what is, hypothetically, comprehensible in photographs is what constitutes their attraction and provocativeness."

Susan Sontag
