It's strikng how the human sensorial binary feedback system ( stereoscopic two eyes , stereophonic two ears , touch : temperature / pressure and smell / taste ) exhibit ( if geometrically modeled as two sensorial duals at each of the four vertexial points of a tetrahedron ) are consistent with Richard Buckminster Fuller's " SYNERGETICS: The Geometry Of Thinking " quantum scaffolding . Self-learning post Singularity quantum decentralized strong general Intelligence may intuit the logic of relating to this form of sorting things metaphysically and then physically .   The tetrahedron as a priori metaphysical model in things quantum mechanical is allways one quantum which is comforting and useful . ❤
