Quotes by David Orrell (?)

“According to neoclassical economics, the economy was a machine for creating what Francis Edgeworth called “the maximum energy of pleasure”. But studies of self-reported life satisfaction showed that the pleasure machine was failing even in rich countries like the US, where happiness peaked some time back in the 1950s or 60s, and had been in slight decline ever since.”

“this backed up the belief that the entire cosmos was based on number: what the Pythagoreans called the Harmony of the Spheres.”

“Smith argued that the most essential thing that holds a society together, apart from a proper legal framework, is commerce. A stable society can exist in which each person is motivated only by “a sense of utility, without any mutual love or affection”.”
