Abstract
I wish to approach this subject from the point of view of a practicing taxonomist wishing to take advantage of numerical taxonomic methodologies for the purpose of solving taxonomic problems or for the purpose of constructing classifications. I regard these as separate operations because, in my view of taxonomy, one cannot construct a classification until one is (reasonably) sure of what it is one wishes to classify. That is, it is first necessary to detect entities that may then be subjected to classificatory methods. Therefore, the process of classification is preceded by a process of detection. We may view the combination of these activities as a three stage process: (1) recognition of differences between individuals, (2) grou** those individuals having common characteristics, (3) assessing the relationships between the groups so recognized.
