Evolutionary Order in the Classification Theories of C. A. Cutter and E. C. Richardson: Its Nature and Limits

Abstract

In recent years, evolutionary order has been used as the favored mode of determining class sequence by classificationists using integrative levels as a theoretical framework for classification design. Although current advocates of evolutionary order are based in Europe, use of the concept in library and information science (LIS) can be traced back to two North American pioneers in classification theory, C. A. Cutter (1837–1903) and E. C. Richardson (1860–1939). Working in the heyday of evolutionism and influenced by the developmental classifications of the sciences of Auguste Comte and Herbert Spencer, Cutter and Richardson introduced evolutionary order as an explicit principle into LIS classification theory, defining it as encompassing a conceptual progression from the general to the specific, the simple to the complex, and the past to the present. This idea proved influential, being appropriated by later theoreticians like H. E. Bliss; it also reinforced the realist tendency of early LIS classification theory. However, for Cutter and Richardson, application of evolutionary order to bibliothecal classifications proved problematic. Cutter applied the concept inconsistently; Richardson viewed it as theoretically ideal, but subject to so many exceptions for pragmatic reasons that it could not be attained in practice. Cutter’s and Richardson’s use of evolutionary order reveals the tension between enunciating a principle of classificatory ordering in theory and applying it in practice.
