The toughening of immigration and citizenship policies in Western liberal states has coincided with an effort to define the cultural values considered the foundation of national identity. Humanistic Sociology was elaborated by Znaniecki (1963, 1968) in response to the perceived failure of immigrants to assimilate to the culture of the host society. As the sociology of cultural values par excellence, it appears timely to revisit the theoretical foundations of Znanieck's approach and examine whether it remains capable of furthering our understanding of contemporary immigration processes. The paper compares Humanistic Sociology with a number of more recent theoretical orientations which have also emphasized the central role of cultural values. Working in an age dominated by behaviourist theories, Znaniecki's humanistic approach was criticized by contemporaries because of what was seen to be its "subjectivist" bias. In hindsight, Humanistic Sociology appears to have considered balance between "objectivism" (structure) and "subjectivism" (agency) according to which agents assume a strategic role in defining their courses of action on the basis of cultural value–structures (personal ideological systems) which are formed through communicative interactions within relevant social groups. This is evident in his concept of the ideological system which provides individuals with a strategic and creative capacity: the generative power of agency.
