A serious study of American society and the means by which it can best preserve its ideal of an ever growing democracy of increasingly responsible and free individuals. Picturing American life first in general and then at community levels, the authors deal sharply with important concepts- the misleading ideas about ""race"", dominant and minority groups with typical characteristics and conflicts as those between Negroes and whites, the richness of cultural diversity, and the person to person, group to group activities that are tending to alleviate discrimination. Against this background a philosophy of democratic human relations for a multicultural society is offered. The ""open doors"" are in the realms of intercultural education, the aspects of which are rooted in history as well as present moral roles of citizens who are in turn products of their environments. As test cases there are examples of the grass roots work done in fair employment, housing, and civil rights- On the whole a generalized and highly theoretical study, but its specific examples and its theme of free inquiry and humanized education establish its value.
