A content analysis of four American political books according to Rokeach's model shows these two values to be most important in diferentiating ideological positions.In searching for a more adequate conceptualization of values, Rokeach (19) isolated two types of values: terminal values, or end-states of existence, and instrumental values, or modes of conduct. Examples of the second type include clean, honest, and polite. Terminal values include salvation, true friendship, happiness, and freedom and equality. It is Rokeach's contention that individuals differ not so much in which values are held, but in the rank ordered structure of the core values, notably 18 instrumental and 18 terminal values.He has demonstrated that when arranging the values ". . . in order of importance to YOU as guiding principles in YOUR life" (22, p. 22), hierarchical differentiations emerge' for such social categories as men and women, hippies and non-hippies, hawks and doves, policemen and unemployed Negroes, good and poor students, retail merchants and sales clerks, Jews and Catholics, Democrats and Republicans. The value survey has been used to study value system stability and individual differences in value system stability (19, 21, 25, 27), value system similarity in rank value as a function of initial ranking (22) and as social indicators with reference to race and social class (26).In addition, the relative positioning of any two values (e.g., Freedom and Equality) in only one type of value system has been useful. Differences in these positions have been found depending on involvement in civil rights demonstrations, occupation, and employment and religion (19). These findings prompted Rokeach's model of political orientation based on the importance of Freedom and Equality as illustrated by Figure 1. Gerald L.
