Editorialist: Despite the importance it seems to have in our lives, money does not really exist  This is evident from the fact that all that would be needed to make money disappear would be a universal loss of belief in it
We witness this phenomenon on a small scale daily in the rises and falls of financial markets, whose fluctuations are often entirely independent of concrete causes and are the results of mere beliefs of investors
Anything that exists would continue to exist even if everyone were to stop believing in it.
