Either/or thinking is a major stumbling block to human development and understanding. In this book Kelso & Engstrom offer a whole new way of looking at the world, awakening a "e;sixth sense"e; that people didn't realize they had. It draws on the profound relationship between nature's many complementary contraries and the paradigm shifting science of coordination called Coordination Dynamics. The human brain~mind, through the multi- and metastable modes of its coordination dynamics, gives rise to a sentient faculty called the squiggle sense. Nature's contraries are perceived not only as opposing polar states, but as coexisting complementary tendencies, symbolized by the squiggle (~). Use this book to nudge your brain~mind into its metastable mode again and again, to better perceive the complementary dances of contraries, and to transcend the detrimental narrow-mindedness of polarized, either/or thinking. As a "e;Metastabilian"e; you can wield your squiggle sense to enhance and advance your life!
