allegory of the cave

"In photography there are no shadows that cannot be illuminated."

August Sander

"To contemplate is to look at shadows."

Victor Hugo

"What difference is there, do you think, between those in Plato's cave who can only marvel at the shadows and images of various objects, provided they are content and don't know what they miss, and the philosopher who has emerged from the cave and sees the real things?"

Desiderius Erasmus
