Affiliation is not a drug or an operation, and that makes it nearly invisible to Western medicine. Our doctors are not uninformed; on the contrary, most have read these studies and grant them a grudging intellectual acceptance. But they don’t believe in them; they can’t bring themselves to base treatment decisions on a rumored phantom like attachment. The prevailing medical paradigm has no capacity to incorporate the concept that a relationship is a physiologic process, as real and as potent as any pill or surgical procedure.

Describing good relatedness to someone, no matter how precisely or how often, does not inscribe it into the neural networks that inspire love.

Overhauling emotional knowledge is no spectator sport; it demands the messy experience of yanking and tinkering that comes from a limbic bond. If someone's relationship today bear a troubled imprint, they do so because an influential relationship left its mark on a child's mind. When a limbic connection has established a neural pattern, it takes a limbic connection to revise it.
