There are priceless things, but for the rest, money represent the ability of humanity to communicate and exchange economic value so I often think about them as a symbol of what we've managed to achieve since the ancient times. And just like we evolved to exchange promissory value on a piece of paper, humanity made huge progress in self-governance and mutual respect. From the dawn ages of absolute kingdoms we've evolved to constitutional monarchies and democratic republics. We've abolished slavery, enabled universal voting in most parts of the world and probably in some decades almost everyone will have the right to marry the person they love. Alan Turing was among the most brilliant persons of his time, yet in his society he ended up injected with estrogen, which left him impotent (he also developed breasts and one year after this therapy he used cyanide to kill himself - http://en.wikipedia.org/wiki/Alan_Turing http://en.wikipedia.org/wiki/Alan_Turing ). If you're in UK, please sign this petition. It would be a huge honor to have on the very symbol of economic exchange Alan's face - a memory of our wrong-doings and of the progress that we made until now and the one that is yet to come.
