"flip yourself head over heels, as if swinging over a waist-high horizontal bar in front of you. Now your heart is on the same side as the mirror-person's heart-but your feet and head are in the wrong places, and your stomach, although at approximately the right height, is upsidedown. So it seems a mirror can be perceived as reversing up and down, provided you're willing to map yourself onto a creature whose feet are above its head. It all depends on the ways that you are willing to slip yourself onto another entity. -- Douglas Hofstader. The Mind's I: Fantasies and Reflections on Self and Soul (co-edited with Daniel Dennett)"

"If a nonspinning inertial observer looks along his axis of symmetry, he sees his coaxial nonspinning inertial peers apparently nonspinning with respect to himself, as we would expect. – Godel_metric

"I also updated the piece to depict a modern market area, a supermarket or shopping mall, filled with glass panels (shamelessly achieved by the use of a paper edge). Instead of the three views culminating in exit points to organic backgrounds or nature, I chose to make the whole space an interior, with backgrounds of a shop, car park and a public sliding-door entrance. The figures are also modernised; cash machine, struggling pensioners, drunks, maintenance orderly and shoppers. -- http://www.schudio.co.uk/blog/2009/m-c-escher-tribute-2-of-3

"as if everything were not in
displacement, detour, transference, metaphor everything is in the love potion of seduction... --Jean Baudrillard writes in Dust Breeding, 2001.

"We used to think that physics described the Universe. Now we know that physics only describes what we can
say about the Universe. -- Niels Bohr. Quoted from "Quantum Psychology. RAW."

"The matrix is the kind of film about the matrix that the Matrix could have produced -- Jean Baudrillard.

"Consciousness is not only a way out of the evolutionary impasse, says Hilbrandt, but also an escape from the snares of Godelization, for by means of paralogistic contradictions this solution has sidestepped the contradictions to which every system that is perfect with respect to logic is subject. So, then, the universum of the
personoids is fully rational, but they are not fully rational inhabitants of it. -- “Non Serviam” from A Perfect Vacuum: Perfect Reviews of Nonexistent Books by Stanislaw Lem.
