Deep friendship may express profound loyalty, but so too may virulent nationalism. What can and should we say about this Janus-faced virtue of the will? This volume explores at length the contours of an important and troubling virtue -- its cognates, contrasts, and perversions; its strengths and weaknesses; its awkward relations with universal morality; its oppositional form and limits; as well as the ways in which it functions in various associative connections, such as friendship and familial relations, organizations and professions, nations, countries, and religious tradition.About the Author: John Kleinig is a philosopher who taught in Australia until 1986 -- working mostly on moral and social philosophy -- when he moved to John Jay College of Criminal Justice, the City University of New York, where he taught mainly police ethics and social philosophy.
