the evolution of goodness.

Have you ever wondered where love, hate, kindness and all our emotions ever come from? I'm certain you've stared and contemplated the diagrams of the human anatomy hanging upon the walls when you visit your local clinics. We have this organ and that organ, it does this and that, perhaps our source of goodness is stored somewhere deep within our brains. We might never know.
We do know that is prominently present within the complex webs of communities, from tribesmen to businessmen, and of course, women too. But that's not the point. I've been wondering and these acts and thoughts are to a certain extent, the fruit of human intelligence. We are nice to one another, to gain favor, for an advantage or whatever intention might be underlying. Yet again, we might be just good towards one another. Selflessness i believe.
And this belief is accompanied by the perhaps myopic perception that we are all just living human beings inhibiting the Earth and instinct drives us for constant survival, to carry on the human race. We are all alive on this planet and knowing that, there isn't much that we can do. Perhaps explore the ends of our planet, and at most explore neighboring planets. For what i ask. ( Purpose is everything, yes? HAHA )
Since we are all alive, shouldn't j we just live our lives and enjoy our times on earth? I don't understand why people must have deadlines or their own money, or why we go to school and try so hard to fathom the occurrences in our world. It is a little too late to develop your own ideals now, we hardly have a choice except the conform to it, anyways, they will most definitely be crushed under the thousands of years of systems and structures that mankind have spun into a complex web. However, it is true that people should be rewarded differently based on the effort they put in. For example, a man who catches a pig in the jungles should be granted the rights to do whatever he wants to it, be it to eat it or to share it with another group of individuals. Yes, we have made use of human intellect to ease our time on this world and we have succeeded and for what we are, we are relentless and still constantly striving for improvement. In short, we are humans and all trying to enjoy our life and what we have, can't we and shouldn't we just try to make those people suffering from poverty or whatever disadvantage live their lives better?
I'd like to believe that some people do realize this ideal and exercise it on every scale possible, and bit by bit, are expressing it through the altruism in our society, to you, to me, to anybody, and everybody.
