"Moving on is of course one of the quintessential expressions of the American spirit, and of the American shallowness. Our religion is the religion of movement; stillness offends our sense of possibility. We dodge the darker emotions by making ourselves into a moving target for them. We feel, but swiftly. This emotional efficiency, this cost-benefit calculus of the heart, is at once a strength and a weakness: you cannot be damaged by what cannot sink in. And so we acquire resilience through transience, and stoicism through speed. We cling desperately to the illusion of our immunity, even after it has just been disproved by experience, and to the fiction of the pastness of the past: we call it “closure,” which is just a decision not to care anymore, and not to let experience intrude any further. We need desperately to know that our insulation is intact."
