You/we ARE a part of nature. If 100% of people care about doing certain things (that they actually have control over) in a certain way, that's the same as nature doing it that way. When it's a smaller percentage, that's just that thing happening in different ways.
Well, that's true in the same sense that everything in the world is just quantum fields interacting. It's true that my mind is part of nature, but my thoughts are not part of an explanatory theory, a framework for predictions, certainly not one that is mostly about genetics and evolution.
Explanatory theories, frameworks and the like are always a work in progress, ergo, never complete - ref Gödel's theorems. What's standard knowledge in the future can easily be utterly incomprehensible today, thus that (being part of a theory or framework) shouldn't be taken as a necessary criteria in talking about things at a level that's more abstract than a theory (which by definition must be about the (mathematical) specifics of specific phenomena), as the parent thread does.
If, as you rightly claim, everything is just interacting fields, should it make or break the argument if the specific interaction of particular (as yet unknown) combinations of fields is as yet unknown?
It can also be questioned if an individual's thoughts are special enough in the grandest scheme of things - or if they're merely a mechanism, that seems special to the body where those thoughts are occurring. For example, moving away from humans: animals have thoughts too, yet their behavior(s) can be abstracted into proper theories (apex predator theory, food chains, etc.) backed with sufficient evidence, without much regard to the thoughts of individual creatures, or even entire species - classifying creatures as predator vs prey is sufficient to study a lot of large scale ecological phenomena.
Of course, there can be various kinds of explanations for why one feels empathy for others - evolution: humans evolved to live in groups and empathy was an asset to group-living, incentives/economic: those that show consideration for others were similarly reciprocated, etc. etc.
PS: I wrote the parent, different alias.
PPS: the dog breeding problems are very real, and I do hope a rich dog-loving American can hire veterinarians and lawyers to simply sue some of the organizations involved in setting/promoting the ludicrous breed standards (resulting in GSDs with sloping backs, pugs that can't even breed without human assistance, etc.). The difference with cows and chickens is one can find enough dog lovers to make an actual issue out of this, compared to (live) cow lovers or (live) chicken lovers.
