Eight Keys to Eden 

SEVEN DOORS TO SEVEN ROOMS OF THOUGHT
1 Accept the statement of Eminent Authority without basis, without question.
2 Disagree with the statement without basis, out of general contrariness.
3 Perhaps the statement is true, but what if it isn't? How then to account for the phenomenon?
4 How much of the statement rationalizes to suit man's purpose that he and his shall be ascendant at the center of things?
5 What if the minor should become major, the recessive dominant, the obscure prevalent?
6 What if the statement were reversible, that which is considered effect is really cause?
7 What if the natural law perceived in one field also operates unperceived in all other phases of science? What if there be only one natural law manifesting itself, as yet, to us in many facets because we cannot apperceive the whole, of which we have gained only the most elementary glimpses, with which we can cope only at the crudest level?
And are those still other doors, yet undefined,
on down the corridor?
