Mainstream interpretations of Keynes's General Theory are surveyed. An
alternative post-classical interpretation is proposed. Keynes is inte
rpreted as treating classical theory as the valid theory of allocation
but this type of theory is of limited relevance for macro analysis. T
he productive sector is characterised by the utilisation mode of activ
ity regulated by the non-allocative multiplier process. However the fi
nancial sector is allocative and Keynes proposed the allocative theory
of liquidity preference. It is argued that this dual conception of th
e macro economy is suggestive of the need for a more realistic method
in macroeconomics.
