"[L]ove isn’t some kind of passive entertainment or fleeting hunger; love involves serious ontological reconfigurations. Or at least there’s a thing that happens, when you grow to know a person, when that person is smart, creative, and kind, when they can surprise you, see the same things you can see, and behave with either such compassion or regularity that you can relax your shields around them, where they become qualitatively more real to you. Almost as real as yourself. Where your mirror neurons jiggle and dance in tune with them, a ghost of them moving alongside you at all times.
Loving someone remakes yourself. But most importantly, even if that ghost fades to a silent unnoticed echo, the impression left by the experience reshapes your ethical reality. You are not alone. Tangibly. Provably. There are other minds. In a way impossible to ascertain merely kicking balls with the shrieking automatons on the playground or banging one in a bathroom or being overcome with the novelty of a new automaton with handsome hydraulics. And this implies an absolute ethical obligation."
