SOME DIFFICULTIES OF ECOLOGICAL THINKING, CONSIDERED FROM A CRITICAL SYSTEMS PERSPECTIVE - A PLEA FOR CRITICAL HOLISM

We probably have simplified matters too much. We tend to talk about sy stems thinking and practice as if we knew what they are. The fashionab le call for ''holistic'' or ''systems'' thinking in ecological issues provides a major example. This much is certain: the quest for comprehe nsiveness, although it represents an epistemologically necessary idea, is not realizable. If we assume that it is realizable, the critical i dea underlying the quest will be perverted into its opposite, i.e., in to a false pretension to superior knowledge and understanding-a danger of which the environmental movement does not always appear to be suff iciently aware. My question, therefore, is this: How can we deal criti cally with the fact that our thinking, and hence our knowledge, design s, and actions, cannot possibly be comprehensive, in the sense that we never ''comprehend'' all that ought to be understood before we pass t o judgment and action? What consequences does this fact imply for a cr itical systems approach to ecological concerns and, ultimately, for ou r concepts of rationality in general?
