I propose that the higher levels of symbolic representation in biological computation, as expressed in human reasoning, exhibit this parallel analog computational strategy between symbolic variables. The lower levels of perceptual processing also have this analog dynamic nature, but they have an additional spatial nature, as suggested in the plotting room analogy, where spatial concepts are expressed in literal spatial form. This allows the constraints, or desired solutions states of the system to be expressed as attractive or repulsive spatial forces in a spatial replica of external space, as a spatial computation in a spatial medium.
