Oliver Sacks in "The Mind's Eye," sets out to explore the relations bec:v,1een our ntinds and our bra.ins. As he asks, "To what extent are we--our experiences, our reactions-shaped, predestined, by our brains, and to what extent do we shape our own brains? Docs the mind run the brain or the brain the mind?" How might Fredrickson answer these questions? Clearly, the experience of love involves the brain in complex ways, but would Fredrickson reach the conclusion that our conscious lives are largely predetermined by our brajn's activity? Does she agree that our conscious choices can change our cognitive habits, as they do in the case of the blind men and women Sacks writes about? Ts it possible for us to consciously cultivate greater "positivity"?
