David P. Barash, an evolutionary biologist and professor of psychology at the University of Washington, writes in the NYT that every year he gives his students The Talk, not as you might expect, about sex, but about evolution and religion. According to Barash many students worry about reconciling their beliefs with evolutionary science and just as many Americans don’t grasp the fact that evolution is not merely a “theory,” but the underpinning of all biological science, a substantial minority of his students are troubled to discover that their beliefs conflict with the course material. "There are a couple of ways to talk about evolution and religion," says Barash. "The least controversial is to suggest that they are in fact compatible." Stephen Jay Gould called them "nonoverlapping magisteria," noma for short, with the former concerned with facts and the latter with values." But Barash says magisteria are not nearly as nonoverlapping as some of them might wish. "As evolutionary science has progressed, the available space for religious faith has narrowed: It has demolished two previously potent pillars of religious faith and undermined belief in an omnipotent and omni-benevolent God."
The twofold demolition begins by defeating what modern creationists call the argument from complexity - that just as the existence of a complex structure like a watch demands the existence of a watchmaker, the existence of complex organisms requires a supernatural creator. "Since Darwin, however, we have come to understand that an entirely natural and undirected process, namely random variation plus natural selection, contains all that is needed to generate extraordinary levels of non-randomness. Living things are indeed wonderfully complex, but altogether within the range of a statistically powerful, entirely mechanical phenomenon." Next to go is the illusion of centrality. "The most potent take-home message of evolution is the not-so-simple fact that, even though species are identifiable (just as individuals generally are), there is an underlying linkage among them — literally and phylogenetically, via traceable historical connectedness. Moreover, no literally supernatural trait has ever been found in Homo sapiens; we are perfectly good animals, natural as can be and indistinguishable from the rest of the living world at the level of structure as well as physiological mechanism." Finally there is a third consequence of evolutionary insights: a powerful critique of theodicy, the effort to reconcile belief in an omnipresent, omni-benevolent God with the fact of unmerited suffering. "But just a smidgen of biological insight makes it clear that, although the natural world can be marvelous, it is also filled with ethical horrors: predation, parasitism, fratricide, infanticide, disease, pain, old age and death — and that suffering (like joy) is built into the nature of things. The more we know of evolution, the more unavoidable is the conclusion that living things, including human beings, are produced by a natural, totally amoral process, with no indication of a benevolent, controlling creator."
Barash concludes The Talk by saying that, although they don’t have to discard their religion in order to inform themselves about biology (or even to pass his course), if they insist on retaining and respecting both, they will have to undertake some challenging mental gymnastic routines. "And while I respect their beliefs, the entire point of The Talk is to make clear that, at least for this biologist, it is no longer acceptable for science to be the one doing those routines."

Those electro-chemical reactions also happen in cultured neurons. And they can be mimicked in culture or in sea slugs by applying exogenous stimulation. Does this mean I can make my petri dish of neurons love me?
Or maybe a different question: studies like this [nih.gov] suggest that "love" is a highly localized phenomenon, presumably related to the specific connectivity of those neurons. How far up and down the network do you need to go to distinguish "love of spouse" from "love of chocolate"? Or are they the same thing, biologically speaking?
The point is that "Love" (etc) is meaningful only as the subjective experience of biochemical states throughout the body, including your own perception of tachycardia and oxytocin, and including memory states derived from training or history. Your subjective experience integrates connectivity and chemistry that is completely unique to you. It may bear some similarities to subjective experiences of other humans, apes, and dogs (but not cats), but you vastly underestimate the integrative nature of the brain if you think that "love" is a little red spot on an fMRI.

No. Those reactions only exist in functioning intact brains. There *are* reactions analogous to portions of the complete reaction existing in cultured neurons, but that's hardly the same statement.
Your link requires JavaScript, so I'm can but guess what you were pointing at. My guess it that the particular experiment drew arbitrary boundaries WRT what they were looking at. Understandable as a brain is too complex to understand, so you start by analysing particular chains that seem to you to be highly connected.
FWIW, when you identify particular chemical agents of stimulation you are tying yourself to one particular implementation. It's true that we currently only have the mammalian brain that we can try to identify emotional state in (I'm even considering avian brains to different to allow much reasoning by analogy), there's no reason to believe that the particular implementation framework is determinate. It's the logical (programmatic) structure that's significant. But this doesn't imply that beauty is either internal or external. While the GP was too certain about his point of view, you equally appear to be too certain about yours. (Well, and so do I, for that matter.) These are matters of belief and definition at the moment, with available evidence only providing a sketchy set of constraints that must be adhered to.
