Abstract

One by one, the noble characteristics that we have chosen in the past to set us apart from other species have fallen before the march of zoological research - othe species can laugh, grieve, use tools, communicate by sound alone, and analyze and respond to complex stimulis well as we. But one trait is ours. We are lisvmakers - eben when we do not use the lists we make. The development of classification has been long and full of false starts, reflective of contemporary intellectual persuasions; from a desire to classify the entire universe, to a conviction that classification is pointless beyond an extemely small universe of discourse. Yet we have achieved an impressive body of theory. We have expressed what Melvil Dewey and his contemporaries only felt. Should we ever use it in a practical way? The upward curve has not been smooth, but for most of those involved, it was and has been fun, and sometimes funny. Only by retaining a sense of perspective can we view the future.
