This raises lots of interesting questions - what things I do and don’t feel, how the world looks different from an oxytocin-less perspective, how a lack of oxytocin changes one's values or goals, etc. But it would be putting the cart before the horse to dive into those questions without first walking through how I learned this about myself and the evidence, so that everybody has an appropriate level of confidence in the underlying assumption.

Caleb also spelled out the physical sensations he experiences with love, and sure enough… [...]
