Abstract

Rosen accuses conventional biology of abandoning its main challenge: the understanding of the nature of life. Biologists generally act subservient to physicists, handicapped by the Cartesian metaphor of the organism as machine. This allows biologists to eschew the issue of intentionality and finalism. The machine metaphor assures biologists that they do not need to appeal to laws other than the ones used by physicists. Rosen argues that the machine metaphor affords the reduction of the organism to its constituent parts.
