The motives for altruism... an interesting topic...
In nature, a monkey will screech loudly to warn his tribe about an approaching enemy tribe, even though this action will cost the monkey it's life because it's giving away it's position. So why would a monkey give up his own life in order to save that of his tribe's? Biologists claim that this is a genetic behaviour, they are programmed to do it - wether they like it or not.
Altruism in nature has been proven to exist, and is part of our genetic make-up. It can be seen with monkeys, insects and many other species, including ours. Therefore, being altruistic is natural.
However, we are humans, and our upper hemispheres of the brain can 'over-ride' our genetic disposition, particularly for traits such as Altruism - so I guess the example of the monkey doesn't solve the question entirely, but it does help; we know the monkey behaves this way because of his genes, that in essence, is his motive.
So what is our (humans) motive for altruism? Is it;
A. To gain approval.
B. To manipulate others (which is the same as A).
C. To adhere to a moral code (which is the same as A and B).
D. Other?
The question is, WHY are you being altruistic?
