Re: Altruism...Does it exist ?
I wouldn't go as far as labelling it 'altruism', but there is examples of something which could be altruism in the animal kingdom; One animal for example, shouting out loud when there's an enemy closing in, thus drawing focus to itself, making sure the others have a greater chance surviving. Also just looks a wolves, there are many examples.
Amongst humans though, that is another matter.
I believe the perversion of society is the madness hindering such a thing as 'altruism'.
The perversion being 'me first', in other words not altruism.
If there is altruism, I'd say it is someone sacrificing themselves, knowing they'll get hurt/die, in order to save another, because even if there is the feeling of 'me' in it, how would YOU know it is there or not?
Altruism as a selfless good deed, is after all forgetting oneself and doing something to help another, although I'm not sure what you mean with 'good', it's quite ambiguous.
