““most people think there are only two types of realities: objective realities and subjective realities. For instance, if you go to the doctor with a pain in your head and they find a wound, the wound is an objective reality. But if the doctor runs a lot of tests and can find no cause for your head pain, then your pain becomes a subjective reality. But there is actually a third level of reality: the intersubjective level, which depends on communication among many humans rather than on the beliefs and feelings of individual humans. Money is a good example of intersubjective reality. As long as everyone keeps believing in money’s value, you can use it to buy all kinds of things. But when people stop believing in the value of that money, then the money becomes worthless,””
