my visual cortex loves the pointsymmetric "tunnel visions" from 1:50<br /> aka: visual cortex form constants, resonance between external and internal patterns<br /> this is also why kids in school are forced to write on "lined paper" aka "ruled paper"...

R is symmetric iff ∀∀\forall x ∀∀\forall y [xRy → yRx].
For any x and y in a set, if x is related to y then y must be related to x for the relation to be symmetric.
Example:
We have the set [1 2 3].
For a relation to be symmetric, if you have (1 2) you must have (2 1). Equally, (1 1) is symmetric.
