‘Type’ in biology is a polysemous term. In a landmark article, Paul Farber (Journal of the History of Biology 9(1): 93–119, 1976) argued that this deceptively plain term had acquired three different meanings in early nineteenth century natural history alone. ‘Type’ was used in relation to three distinct type concepts, each of them associated with a different set of practices. Important as Farber’s analysis has been for the historiography of natural history, his account conceals an important dimension of early nineteenth (...) century ‘type talk.’ Farber’s taxonomy of type concepts passes over the fact that certain uses of ‘type’ began to take on a new meaning in this period. At the closing of the eighteenth century, terms like ‘type specimen,’ ‘type species,’ and ‘type genus’ were universally recognized as referring to typical, model members of their encompassing taxa. But in the course of the nineteenth century, the same terms were co-opted for a different purpose. As part of an effort to drive out nomenclatural synonymy – the confusing state of a taxon being known to different people by different names – these terms started to signify the fixed and potentially atypical name-bearing elements of taxa. A new type concept was born: the nomenclatural type. In this article, I retrace this perplexing nineteenth century shift in meaning of ‘type.’ I uncover the nomenclatural disorder that the new nomenclatural type concept dissolved, and expose the conceptual confusion it left in its tracks. What emerges is an account of how synonymy was suppressed through the coinage of a homonym. (shrink)

The entry of time and history into biological systems of classification is perhaps the single most significant development in the history of biological systematics in the modern era. Darwin's claiming that descent is ‘… the hidden bond of connexion which naturalists have been seeking under the term of the natural system’, rather than seeing the answer in the multitude of previous attempts to resolve the problem in terms of morphological affinities, analogies, and complex relations of resemblance, marked the turning point (...) in a long search into the meaning of biological taxonomy, and allowed the development of Darwin's insights by Haeckel, Plate and others into modern phylogenetic systematics.

During the nineteenth century an intellectual elite formed in Germany which owed its status primarily to educational qualifications rather than to hereditary rights or wealth. With the ascendency of this elite, which Fritz Ringer has called the German ‘mandarins’, came their acceptance as the spiritual bearers of culture in German life. Politically they controlled the life of the Reichstag and hence were the spokesmen of the nation. As an intellectual elite they fed a diet of German idealistic philosophy to the (...) educational class. The university professors, as the most influential members of this class, spoke for the mandarin elite as a whole; and most cultivated Germans looked to the academicians for their understanding of political and cultural issues. Hence, German academic opinion became a sort of ‘mandarin ideology’. (shrink)
