Right Brain/Left Brain
The human brain is divided into two hemispheres: the left brain
and the right brain. The hemispheres of the brain are objects of
duality, equal but opposite.
Left brain logic is vertical, rational, deductive, and sequential.
The left brain uses analytical thought. This hemisphere of your
brain is strongly bonded to the concept of duality. To the left
brain, there are only two possibilities: right and wrong.
