This article is concerned with texts by Frantisek Cermak devoted to issues of Czech language cultivation. Four major topics are analyzed: standard vs. common Czech, written vs. spoken Czech, prescriptivism and the native language of Czechs. Various problems in the analyzed texts result from an unclear methodological background. Many concepts are used without argumentation: Cermak fails to substantiate their suitability for his language description. We can find uncorroborated generalizations which can be interpreted as Cermak's communicative strategy. Many statements are rather impressionistic and are not based on relevant language observations. With regard to these findings, the author of this paper argues that a deep-reaching dialogue should be held, which may help to clarify the indeterminate situation in Czech linguistics concerning issues of language cultivation.
