I think that one of our most important tasks is to convince others that there's nothing to fear in difference; that difference, in fact, is one of the healthiest and most invigorating of human characteristics without which life would become meaningless. Here lies the power of the liberal way: not in making the whole world Unitarian, but in helping ourselves and others to see some of the possibilities inherent in viewpoints other than one's own; in encouraging the free interchange of ideas; in welcoming fresh approaches to the problems of life; in urging the fullest, most vigorous use of critical self-examination.
