Will Self warns against the false prophets of the new priesthood of economics who base their analyses and predictions on "spurious notions of human behaviour". "In place of the vulgate we require the holy books of economics to be written in the language we actually speak, and along with this we should actively seek a liberty of individual conscience, so that we communicate directly with Mammon, freed from the intercession of a priesthood who, when not arguing about how many angels can be fitted on the head of a pin, are spending our money producing elegant but utterly spurious mathematical models of possible future angel-on-pin scenarios."
