Minding your languages
Ram Guha on a different kind of two-language theory:
"Between 1920 and 1980, or thereabouts, Bengali and Marathi were the only bilingual intellectual cultures in the world. The French write, think and speak exclusively in French; the English, in English. Yet in Pune and Calcutta, original works of scholarship were being written and discussed both in English and in the language of the bazaar."
