If we define selflessness for the sake of this thread as non-personal concern which leads to sacrafice of organism A to benefit organism B, without organism A doing it for personal benefit of their organism-self.
- Richard Dawkins
For example, your brothers and sisters contain a lot of your genetic material, when people sacrafice say a small portion that can help someone who shares half your genes, its beneficial to genetic propagation of your genes (or genes that happen to reside in your body) but its not selfish, the person doesn’t have a concern for their own body, they have a concern for doing what they can to protect another body, which has a large portion of your genes.
It might be unconsciously ‘selfish’ (selfish is a word to elucidate, theres no awareness for selfishness to play into here, and its not about the individual organism) because its propagating your own genes through selfless sacrafice, but its still not oriented around the individual organism and their own life/greed/ambitions (past genetic ambitions about other ORGANISMS)
Does this highlight the issue at all? theres rodents or whatever that will squeal when a predator comes around, putting itself at risk, to warn its family, not because it couldn’t escape, but because its near-by family is a huge resource of shared genes.
