SOCIAL SCIENTISTS AND POLITICAL THEORISTS FROM ACADEMIC INSTITUTIONS IN PHILADELPHIA TO EXPLORED DURING 1976 AND 1977 ALTERNATIVE TRADITIONS OF SOCIAL JUSTICE AND WAYS IN WHICH THESE CONCEPTS MIGHT BE INTEGRATED INTO COURSES IN CITY PLANNING, PUBLIC ADMINISTRATION, URBAN SOCIOLOGY, AND CRIMINAL JUSTICE PLANNING. THIS READER SUMMARIZES THE ASSUMPTIONS OF FIVE DISTINCT SOCIAL JUSTICE TRADITIONS: LIBERAL, SOCIAL DARWINIST, SOCIALIST, RELIGIOUS, AND CLASSICAL GREEK. EACH TRADITION IS INTRODUCED WITH A GENERAL STATEMENT OF ITS THEORETICAL STANDPOINT FOLLOWED BY REPRESENTATIVE SELECTIONS THAT ADDRESS ISSUES OF PUBLIC POLICY SUCH AS THE DEFINITION OF IDEAL JUSTICE, RECIPROCITY, EQUITY, AND PERSONAL VIRTUE. THESE SELECTIONS ARE ORGANIZED AROUND FOUR THEMES: (1) HOW DOES ONE LIVE THE GOOD LIFE? (2) WHAT IS THE RESPONSIBILITY OF THE POLITICAL LEADER OR PUBLIC ADMINISTRATOR? (3) WHAT IS THE ATTITUDE TOWARD POVERTY AND ECONOMIC EQUALITY? AND (4) WHAT IS THE MEANING AND FUNCTION OF THE CITY? EACH SECTION ALSO INCLUDES WRITINGS BY INDIVIDUALS WHO DISAGREE WITH PARTICULAR POLICY PROPOSALS OR WHO QUESTION THE ASSUMPTIONS OF THE TRADITION. (AOP)
