Bloomfield and historical linguistics
Bloomfield worked in both historical and synchronic linguistics. To the former, he contributed: (1) a large amount of work in specific fields; (2) scrutiny of the nature of historical linguistic investigation; and (3) an analysis of the phenomenon of linguistic change. In his Language (1933), he did not narrate the procedures involved in synchronic investigation, nor did he set forth the steps to be followed in analysis. In his exposition of the results of diachronic linguistics, his approach was one of respect and admiration for the achievements of nineteenth-century historical linguistics. Since he accepted the (often disputed) postulate of the regularity of sound-change, he defended it by indirect persuasion in setting forth the arguments by which it is confirmed. His view of the causation of phonological and morphological change is interpreted as an anticipation of later sociolinguistics. In so doing, he restated his predecessors’ and his own insights, thereby rescuing them from the ministrations of their would-be defenders.
