In the real world, which not only bestows rights but itself imposes enormous obligations—in this world, if we want to behave like civilized human beings—come to that, if we want to behave like Christians—we should, indeed we must, put into practice only those ideas which have been tested against reason and experience, which have been tempered in the crucible of empirical analysis; in a word, we must act rationally, not mindlessly as in a dream or in delirium, so as not to harm our fellow man, not to stifle him or destroy him.
Rights and obligations! It's going to take everything we've got to manage that balance.
