Any study of the philosophical literature dealing with the cluster of topics generally identified as ‘functional description’, ‘functional analysis’, and ‘teleological explanation’ naturally raises the problem of confirming, disconfirming, or at least relating the alternative logical models proposed by philosophers to the actual usage of biologists. A close examination of current biological literature reveals that acceptance or rejection of what philosophers or sociologists might call a ‘functionalist’ perspective or approach is not significant for the division of biologists into schools or factions. It is certainly not the case that a functionalist perspective distinguishes the wholistic or organismic faction from the molecular biologists. In fact, molecular biologists shift back and forth from ‘functional’ to simple causal perspectives with considerable indifference. This is particularly true of the literature based upon the so-called operon hypothesis developed by the Nobel laureates Jacob and Monod.
