   • 1980, Philip Drew, “Jane Austen and Bishop Butler”, in Nineteenth-Century Fiction, volume 35, number 2, pages 141–142:

     It is plain that for Jane Austen the settled habit of moral behavior was of far more importance than spontaneity of moral response, though that in turn was preferable to a calculated weighing of advantages, a point well illustrated when Elizabeth ironically advises Jane that if she is in doubt about whether she ought to accept Bingley she should decide the matter by striking a felicific balance.

   • 2005 February 7, James Gardner, “Remembering a Great Institution”, in New York Sun, retrieved 25 January 2009:
