Just a note - if you knew people would only do favors when it had some overall benefit for them, you would do the same, it wouldn't be a matter of trust. You wouldn't feel any sense of trust, and neither would any one else, they would just be perfectly rational. But I see your point.
Again, it's not about
knowing.
Besides, we can know, and yet we still feel the emotion and we don't feel a need to do away with it.
Fair 'nuff.
So some random evolutionary mutation [1] produced mirror neurons, which proved to cause the species to form stronger societal bonds, based on favor-swapping and another emotion(and act of intellect), trust, [2] and thus last longer than those species who had formed societies for pure benefit? [3]
Would that be a correct sum of your position?
Notes to the above:
1. Mutations aren't "evolutionary". A series of mutations, which were random in their occurrence, were non-randomly selected by environmental pressure ultimately to produce mirror neurons (although each stage between no-mirror-neurons and mirror-neurons was evolutionarily beneficial).
2. Compassion, favour-swapping, and trust do all go together. But it's not just about favour-swapping. It's also about kin selection. Your siblings and your cousins have some of the same genes as you, so it's in your genes' best interests to look after your kin.
3. I'm not really sure what you mean by a society formed for pure benefit. All societies are formed for the benefit of those in the society. The point is that cooperative societies are the most effective kind.
And, as you say compassion is now not a really essential emotion anymore, and is often easily ignored, or deformed, by people. So are we potentially in the process of losing the emotion of compassion?
I don't think we can make that assumption. Evolutionary pressures are very different in modern human society from those that our distant ancestors faced. And at the moment, there are still social benefits to all of us to be compassionate because it is expected of us and it makes others trust and like us. We need to be trusted and liked to attract partners. So no, compassion is not "inessential". My point was merely that it evolved in circumstances very different to our own and is therefore no longer running at peak efficiency in evolutionary terms. That is not a moral judgement, by the way.
Whenever I make a similar statement to an atheistic evolutionist, they correct me and say "No, there is no end - so nothing evolved in order to achieve any end."
Fair enough. That's my sloppy language again.
But the point remains: it turned out to be beneficial, at each stage of the evolutionary process, for human beings to be compassionate.
And I understand them, but then that raises the question sort of contained in the OP: why do humans percieve some things seen as "ends", as "goods" or "good" (even when these these things are in opposition to pure survival-oriented behavior)?
I mean we talk about a will to live, and about genes wanting to reproduce and pass themselves on, but unless we're real pantheists, we know genes don't "want" or "will" anything.
Well, I'd recommend reading
The Blind Watchmaker for an accessible but in-depth discussion of how a self-replicating molecule can appear to "want".
Basically if you have something that naturally (blindly) makes copies of itself, the better and more efficiently it can do that, the more copies it will make. From an evolutionary point of view, bodies are nothing but vessels for genes.
Cantata;
So compassion only really informs us about the sort of behaviour that prolongs the survival of certain genes?
Would you agree?
No.
It informs us about the sort of behaviour that
used to prolong the survival of certain genes, before modernity came along and interfered.
