Glottochronology is a methodological deadlock. — Linguistics

"Languages are no more than the keys of Sciences. He who despises one, slights the other."

"Linguists continue to arrogate to themselves the competence of these other disciplines. Just as experts from other sciences do not intervene in linguistics, so linguists should not tell historians, archaeologists et al what to do or how to do it just because the latter’s finds are at variance with linguistic wishes."

"אַ שפּראַך איז אַ דיאַלעקט מיט אַן אַרמיי און פֿלאָט"

"Lashd into Latin by the tingling rod."

"Its as if were higher apes who had a language faculty inserted."

"Jede Sprache is ein System, dessen sämmtliche Theile organisch zusammenhängen und zusammenwirken."
