In the Preface to his recent philosophy of biology (1988) and in his earlier Growth of Biological Thought (1982), Ernst Mayr emphasized that recent progress in evolutionary biology is a result of conceptual clarification, not a consequence of improved measurements or better scientific laws. Although complete agreement on the meaning of key concepts is not essential for all communication in science (see Hull 1988, pp. 6-7,513), we likewise believe that conceptual clarification is perhaps the most important key to progress in community ecology. In order to investigate some of the reasons that might explain why community ecology has been unable to arrive at a widely accepted general theory, in this essay we analyze “stability,” one of its most important foundational concepts. After reviewing the stability concept and sketching its associated problems, we assess the epistemological status of four difficulties with the concept.
