The present shows us that the future is going to require significant changes and evolutions in humanity for there to even to be a future that involves humanity.
The present shows people struggling to decide which direction to go from here. There is much discussion and rhetoric to this effect. One thing is for sure, we need to depart from our present methods of living on this planet.
The current global condition for humans is like a group of people standing on a big rock and the rock is rapidly heating up to the point that their shoes are melting. They are arguing about why the rock is turning to hot lava and who's fault it is and which way to go while their feet begin to burn. Logic in this situation would have it that...
Any place is better than here, lets leave.
There is not that much that is right with the present way of living on this planet. We cannot crystalize the new direction with laws or doctrines.
We will always be leaving the present until we find an eternal present and the confluence of humans with each other and the planet. The Earthship concepts are an attempt to place stepping stones across the abyss toward this eternal present.
