Altruism in the evolutionary sense doesn't necessarily consider immediate benefits. It's not, as noted below 'identical to the everyday concept'.That's why I mentioned the neighbours who helped each other. The altruistic acts weren't immediately repaid. But helping each other formed an alliance that didn't exist before. And the guy that refused to help was effectively ostracised. It should be obvious that being part of a group is evolutionary beneficial as opposed to having to go it alone.No, altruism in the sense we are discussing are altruistic acts that are more than simply acts that creates in the actor an expectation of a future reciprocal act. Altruistic acts measure the immediate costs and benefits in terms of reproductive fitness or expected number of offspring. Behaving altruistically, one reduces the number of offspring he is likely to produce himself, but boosts the number that others are likely to produce.
And if you were quoting Stanford it would be a good idea to state that and give a link in case people might think you were lifting someone else's work. Allow the me to quote the next line: Biological Altruism (Stanford Encyclopedia of Philosophy)
'So by behaving altruistically, an organism reduces the number of offspring it is likely to produce itself, but boosts the number that other organisms are likely to produce. This biological notion of altruism is not identical to the everyday concept.'
But further on:
'Why might a social behaviour reduce an animal's short-term fitness but boost its lifetime fitness? This could arise in cases of ‘directed reciprocation’, where the beneficiary of the behaviour returns the favour at some point in the future. By performing the behaviour, and suffering the short-term cost, the animal thus ensures (or raises the chance) that it will receive return benefits in the future.'
This is exactly what I was talking about. And brave soldiers sacrificing themselves for others? Well, we are not compelled to follow our evolutionary instincts. We are socially conditioned to admire courage and sacrifice. It grants one a certain stature. No-one wants to be thought a coward. In extreme situations, especially considering the camaraderie of fighting men, that sacrifice is taken to the extreme.
