Whilst we are naturally selfish these qualities evolved as a method of restraining individual selfishness and building more cooperative groups, which are essential to our survival.
I sort of agree but I would change it to "these qualities evolved as a method of
restraining individual selfishness and building more cooperative
related groups.
Evolution does set some limits though.
Do you know about Hamilton's rule?
rB>C
- r is the relatedness of the recipient to the actor, defined as the probability that a gene picked randomly from each at the same locus is identical by descent.
- B is the additional reproductive benefit gained by the recipient of the altruistic act.
- C is the reproductive cost to the individual performing the act.
This means that genes can
only increase in a population when Hamilton's rule is true, else those genes will be selected against and decrease in frequency within the population.
IOW, altruistic acts should
only occur when
the altruist gains a reproductive advantage greater than the cost of the altruistic act.
This is what evolution hardwired into our brains and this is indeed how humans interact and cooperate.
Kinship and altruism: A cross-cultural experimental study
We show that individuals from two different cultures behave in accordance with Hamilton's rule by acting more altruistically (imposing a higher physical cost upon themselves) towards more closely related individuals. Three possible sources of confound were ruled out: generational effects, sexual attraction and reciprocity. Performance on the task however did not exhibit a perfect linear relationship with relatedness, which might reflect either the intrusion of other variables (e.g. cultural differences in the way kinship is costed) or that our behavioural measure is insufficiently sensitive to fine-tuned differences in the way individuals view their social world. These findings provide the first unequivocal experimental evidence that kinship plays a role in moderating altruistic behaviour. Kinship thus represents a baseline against which individuals pitch other criteria (including reciprocity, prosociality, obligation and a moral sense) when deciding how to behave towards others.
Just keep in mind that we are all part of the Bell curve and this is how the
average person behaves and for
very good reasons.
In our evolutionary history humans who were '
too selfless' and '
too altruistic' would have been selected against, in accordance with Hamilton's rule, since they would compromise their own reproductive success.
The reverse is of course also true, since we are social animals.
Humans who were
'not selfless enough' and
'not altruistic enough' would also have been selected against, making us more cooperative.
IOW evolution has achieved an optimal balance between selfishness and selflessness, based on reproductive success.
Hamilton's rule sets a hard upper limit to how far cooperation and altruism
can evolve and evolution and natural selection
cannot cross that boundary to reach
rB=C and never will
rB<C.
This has implications on the size of the groups humans evolved to cooperate in. Again evolution had to achieve a balance.
A larger cooperating group would always outperform/overpower a smaller cooperating group, all else being equal. But if the group is too large and relatedness too small, Hamilton's rule kicks in and over time cooperation breaks down.
We seem to have evolved to live in groups of around 150 individuals, this is known as
Dunbar's number.
Well what it entails to me is that altruism, empathy, and gratitude all underpin moral behaviour.
You are focusing just on what you judge to be the good and ignoring the rest of human nature. It also entails exploitation and deception to an even larger degree.
Hamilton's rule also has a dark side. It predicts that individuals should not cooperate with unrelated individuals* and unrelated groups, in fact, if you could find any way to exploit them it would be to your advantage and the more selfish you acted towards them the better for yourself and your group.
This results in the conflicting moral frameworks I have mentioned a few times earlier in the thread and that you denied. Humans have evolved to cooperate with the in-group and oppose and exploit any out-groups. This is human nature the "good" and the "bad" are part and parcel of the same package and present in every human.
You cannot fixate on one and ignore the other.
Now some good news as I see it.
Evolution has found no foolproof way of giving the individual a way of directly judging relatedness, although pheromones and smell have been shown to have an effect. People consider the family they grew up in as related, even though they might in reality not be, evolution
can be fooled. The same principle applies to the group.
In modern life this often results in confusion and conflicting emotions. People have a natural instinct to mentally classify others as belonging to either the in-group or the out-group. Diverse criteria are used for this classification depending on the group under consideration, therefore a person could at the same time be in your in-group and your out-group.
It is not true that natural impulses are stronger than social ones in every circumstance. Quite the contrary. Socialization of human being is a long process where social motivation reshapes, redirects or even inhibits natural impulses.
Agreed.
I think culture can push cooperation past Hamilton's limit, whereas evolution must fail.
Some natural impulses can either be in inner contradiction or natural and social impulses can fight each other.
I think problems arise when they do fight each other and the fighting should be minimized if possible.
The more they conflict, the more individuals in society will not conform to them but you will never be able to eliminate all conflict.
I'm not sure where I'm heading with this, but it seems more like a way to structure society so that good morals will naturally dominate bad morals.
* Another evolutionary balancing act grounded in instinct. Humans want to cooperate with related individuals and groups but want to reproduce with unrelated individuals.
