“The photographic lens does not see the forms. They must, therefore, be immaterial—and yet I can see them. Are they, then, the shades of the dead, as Dagerlöff appears to believe? But why should I see the dead revive because I see things 100 years in advance? I’ve only ever seen the present— or, more exactly, the fraction of the present that will endure for a long time. Let’s silence our imagination and appeal to the rationality that has never deceived me. What is it in the present that lasts the longest, and which is immaterial? Answer: ideas. After the bodies, the cadavers, the skeletons, it is the ideas of human beings that are most durable. I am therefore seeing the forms of ideas. Judging by the manner in which the majority of brains function, there’s nothing astonishing in their being a trifle vague—but why do they have faces? An idea has no face.”

Jacques Spitz, 1939
