Revolution

Revolutions:
Action research - cyclical learning

Sixteenth-century astrologers serving princes and generals spoke of "revolution" to desig­nate abrupt and unforeseen events determined by the conjunction of planets - that is, by forces beyond human control.

Thus the original sci­entific meaning of the word, conveying regularity and repetitiveness, came, when referring to human affairs, to signify the very opposite, namely, the sudden and unpredictable.

God is constant, man is irregular

God revolves/reliability, man revolts/unpredictable
