"As for nationalism and universalism, it is natural and not culpable to have more affection for one's own country or race than for another, but this should not interfere with one's sense of justice which should be impartial. Your question whether a Jew can live as freely outside Israel as in it is one which a Jew could answer better than a gentile. I should certainly have thought that a Jew can live quite freely in England, but I do not know enough about other countries to give an opinion. You ask if any true religion is compatible with real science. I do not understand this question. If any religion is true, it must be compatible with science. For my part, I do not think that there is such a thing as a 'true' religion."
