John Davis finally, at least to my mind, gets this discussion properly
to connect with modern economics. As the Camerer, Loewenstein, and
Prelec survey on "Neuroeconomics: How Neuroscience Can Inform Economics"
in the March 2005 Journal of Economic Literature convincingly argues,
"rational choice theory", or the standard economic theory of decision
making, is very incomplete in very well-understood ways: "As economists,
we are used to thinking of preferences as the starting point for human
behavior and behavior as the end point. A Neuroscience perspective, in
contrast, views explicit behavior as only one of the many mechanisms
that the brain uses to maintain homeostasis, and preferences as
transient state variables that ensure survival and reproduction." (p. 27)
One consequence of this reconceptualization, having significant effects
now in behavioral economics, will be force historians of economic
science to historicize such ideas as individualism and rational choice,
instead of trying to "get at" their "essential natures". Surely no
historian of economics has any privileged perspective on "essential
natures".
