The whole tragic system seemed to be based upon an extraordinary convention, as incomprehensible as the theory of money, which (so she had been told) bore no relation to the actual supply of gold. It was chance which had made men turn gold into their symbol, rather than stones; it was chance which had made men turn strife into their principle, rather than amity. That the planet might have got on better with stones and amity – a simple solution – had apparently never occurred to its inhabitants.
