Question

As I understand it, you believe in altruistic actions.
My question is:
A. What does science say about the subject, and is there documentation of such an action?
B. Morality is embedded in us. A moral act is done מתוך the feeling that this is what should be done. If a person acts against his intuition, he may become confused and feel regret and confusion—bad feelings. So when a person follows his way of thinking, he actually feels good about it, and so there is in fact a hedonistic aspect to the matter.
 Doesn’t this lead to the conclusion that an act cannot stem from a purely moral motive alone?
