In Dealing with Feeling, the latest work of speculative fiction by Marc Brackett, the fantasy is simple: What if, at long last, we could tame the human heart? What if we overcame “the biggest obstacle to achieving our best selves” by developing “care and compassion for ourselves”? What if we could “gain control over our lives,” find “success — at home, at school, at work, and everywhere else,” could solve “virtually every problem we’ll ever have, from the personal to the political to the global,” and finally “create the life” we want? “The mind is its own place, and in it self/can make a Heav’n of Hell, a Hell of Heav’n/What matter where, if I be still the same,” John Milton asks. What, asks Brackett, if we were no longer prisoners of that place, but its God?
