I have the feeling that all on this site are after the same thing - peace on earth and goodwill to all man.
And that certainly seems to be the trend if we look at our violent past and compare it with the, well, “almost peaceful” present. The question though is: are we consciously making this happen based on some deliberate decisions or is non-violence simply more advantageous in Darwinian terms? I believe it is the later one and that makes me optimistic to think that one day we might really find a heaven on earth—or something as close to it as possible. And if this is a universal trait in the whole cosmos, maybe there is even a chance that one day even an all-loving God will be born.
It must be said that the most consitently violent force has been Christianity (1700 years of it!). No, man has not changed one iota. If pushed (as in the case of the Watts riots) he can be very dangerous.
We are not making this conciously happen, (look at what we are still doing in the world).
As to Darwin? He showed us Evolution but nothing more. Behaving like grown adults comes and goes. Will it ever change is argueable. We need a world government but we are centuries away from this. And this government must be controlled by people as one of the acient Greeks said, by intelligent men. Let’s go for this!
I don’t expect that ‘one day’ you spoke of above to ever arrive.
