PT Journal AU Faltynek, D TI And thus the Circle has got its seventh publication SO Bohemica Olomucensia PY 2013 BP 318 EP 328 VL 5 IS 4 DI 10.5507/bo.2013.033 AB By simple argumentation I show that it is not possible to build explanation of the history of linguistics on nonlinguistic (nontheoretical/nonconceptual) facts. External coefficients are very important in the development of linguistic science, but in the explanation of linguistic history they must be only ilustrative. This broad issue is presented by contention about linguistic purism, whose two protagonists are Prague Linguistics Circle and Jiri Haller. ER
