Esprit Jouffret’s Theory about the 4th dimension

4thEsprit Jouffret’s Theory about the 4th dimension

David Kranz. Since 1987 I have researched and worked with the stereoscopic image.

Duchamp’s “Large Glass” is based, among many other things on a philosophical concept that goes back to Plato. Jouffrets theory explained metaphorically through shadows: In our three-dimensional world a shadow is two dimensional, so a shadow thrown by a figure from a four-dimensional world would be three dimensional in our world. “Everything that has a three-dimensional shape is a projection of our world from a four-dimensional world, and my bride, for example, is a three-dimensional projection of a four-dimensional bride. Okay. Since it’s in glass it’s flat, because my bride is a two-dimensional representation of a three-dimensional Bride, which also is a four-dimensional projection of the bride’s three-dimensional world. ”
