The amount of the population that doesn't comprehend being altruistic or being selfless never ceases to amaze me but it really shouldn't if you are incapable of imagining something then you cannot believe in it. But until the majority of the worlds population understands this the species is doomed to extinction. I just can't imagine not understanding this naturally.
There's no such thing as altruism.
This is a useful primer http://www.humantruth.info/altruism.html but there's lots more social science, evolutionary psychology research if you prefer 'proper' papers and articles.
Its a bit of a downer but once you come to terms with this, its actually quite liberating.
