One’s language is a spiritual location, it houses your soul. If you were born in America all essential communications, your deepest communications with yourself, will be in English—in American English. You will neither lie nor tell the truth in any other language. Without it no basic reckonings can be made. You will not reflect on your own death in Hebrew or in French. Your English is the principal instrument of your humanity. And when the door of the gas chamber was shut many of the German Jews who called upon God for the last time inevitably used the language of their murderers, for they had no other.
Quote from "A Jewish Writer in America" (The New York Review of Books)
