Evidence

In the same way that Einstein had ended our illusion that time stands outside, and apart from, space, Keynes wanted to stop us thinking of money as a thing, as simply another commodity, that stands outside, and apart from, our other activities in markets and workplaces. — Yanis Varoufakis, Technofeudalism, 87
