Since money is a system human beings created, and since we are all inculcated, one may even say brainwashed, into the reasoning that flows from that system, I have often wondered what a world without money may look like. Since the world of money is all pervasive and there is actually nowhere on earth one may live in a large society without it, it is a matter of pure speculation whether or not civilisations could be created without it.
I am sure there would always be culture and I am sure people would always gather together but money is an expression of our desire to get something for giving something (the act of selling) which is not an intellectual but an animal response. It is however indicative of our aims in dealing with each other. To have parity, if not benefit and the intellectual side of that nature is that we could teach a difference of focus.
With a strong and worthwhile focus that directs this desire it seems to me we could build a civilisation using the less selfish sides of our minds even if it was a mix-and-match of areas where money was involved and areas where it was not.
The gaining of knowledge of the universe is one area where I would begin to take money right out of the equation from mining of the materials for use in space to the astronauts themselves. Not the least because I think it absurd to take this financial system with us into space.
