everybody on their own..

going back to a thought that everybody is selfish.. let's say egoistic.. not really a egomaniac, but we (most of the time) act and think in the way of "I would" "I need" "I did not" I and I and I.. why? well each and every form of life is trying to survive, survive everything, be a living thing, not a dead and forgotten thing.. animals, humans, flies, flowers... everybody and everything (even the stones) therefore all those things, all humans act in a way of a selfish act. Kant got the point, but yet there are some moments when we need to shout "aaaawww" heroic moments, people saving other people, even when the risk is so high that they might die. do we see such behaviour in animal world (do not count humans among animals)? I can't remember that a fly would fly so fast that it would bump into another fly which would just be at a risk of death (hand smashing it on a purely white wall) where are these intentions coming from? how come that most of the time (and kids need to go through such grow when the world is just about them and them and them) think about ourselves and then in some other moments we act as heroes (taking note that heroic act for me is just what I have described above)
