Creativity

The "or" makes the two dimensional want to become three dimensional.  It makes straight lines jagged. It is responsible for thinking outside the box.   But the "and" is what keeps this thinking grounded.   It was what prevents creativity from becoming fantasy.  It is what connected the propositions that became the Theory of Relativity and put them into a logical sequence.  Thus, the "and" and the "or" must work in tandem for creative thought to become meaningful, for it to become anything more than manic ruminations. In sum, the "or" may be responsible for that initial burst, that escape from the confines of conventional thought, the severing of existing connections.  But as long as there is genuine creativity, the "and" is there, trying to keep it real.

(Of course, the "and" in one creative endeavor, say painting, may differ in character from the "and" in another, such as an innovative mathematical or scientific theory.  In the latter, the "and" may consist of logical connections, while in the former, it may consist of an idea, or in the case of a novel, a plot)
