Biopsychism: life between computation and cognition

Abstract

ABSTRACT The computational metaphor of organisms as phenotypic automata controlled by a genetic programme has been replaced by the cognitive metaphor of organisms as intelligent agents making decisions about how to use their genomic and environmental resources. This metaphor facilitates novel ways of thinking about organisms that defy the assumptions of the old machine metaphor. But like all metaphors, the cognitive metaphor discloses important similarities at the expense of eclipsing significant dissimilarities. I argue that although cognitivism carries with it the crucial insight that living organisms are agents rather than mere automata, this metaphor distorts the nature of biological agency by over-intellectualizing, which risks eliminating the distinction between life and mind. I trace the Cartesian root of these metaphors and argue that it generates a dilemma between mechanism and intellectualism. To capture the middle path that most organisms occupy between these two extremes, I propose an ecological account of natural agency.
