Human brain has two hemispheres which function differently

From classical times, it has been known that the human brain has two distinct ways of thinking and knowing. Many scientists, intellectuals, and authors have given names to these two types of intelligence or cognitive styles.  Some examples are:

	Left Brain	Right Brain
	RATIONAL
Maslow	Rational	Intuitive
Bruner	Rational	Metaphoric
Koestler	Associative thinking	Bisociative thinking
De Bono	Vertical	Horizontal or lateral
Bronowski	Deductive	Imaginative
Shopenhauer	Objective	Subjective
Freud	Secondary process	Primary process
Jung	Causal	Acausel
Langer	Discursive symbolism	Presentational symbolism
Neisser	Sequential processing	Multiple processing
Kubie	Conscious processing	Preconscious processing

Whatever they are labeled, the effective use of these two distinctive processes is vital for all creative human thought, for the full functions of the human brain.
