Is love captured by physics? It is captured by physical laws (i.e. a logically omniscient being could derive a description of love from them)

This is still the same "statement of faith" that I criticized at greater length, later in the thread. Love is an experience, and you will not even find a description (to say nothing of an explanation) of an experience, in any sort of physics that we know about, nor in any other discourse that can be reduced to that sort of physics. Our mathematical physics describes what the shadows on the wall of Plato's cave are doing, but it says nothing about what anything is. The nature of experience is a problem of the latter kind, which is one reason why explanations of it in terms of matter, number, and computation are hollow. Then there is the more specific problem that the atomized ontology of physics is an ill-suited place in which to find complex unities like conscious states, which is why I say there will need to be new formal developments in physics, and new physical discoveries in neurobiology, before even a revised physicalism has any chance of explaining us.
