Archaeological classification: theory versus practice

Classification is fundamental to all artefactual archaeology, and no one who works with artefacts can be unaware of the doubts that surround many classifications. How similar are the similar things that belong together? How different are the different things that belong apart? What do the classes of similar things actually amount to? This paper looks at some fundamental questions of classification, believing that classification is too important a practical matter to be left to the theoreticians.
