This essay deals with the concept and problem of political rationality. Following the ancient conception that the absence or presence of rationality manifests itself in choice situations, we try to explore at first the specific characteristics of political choice, then turn to a discussion of the criteria for rationality, considering process, goal contents and structure criteria, point to the restrictions for rationality analytically inherent in any choice structure, and try in the end to make clear the difference between these analytical (i.e. principally unremovable) restrictions and the (principally removable) "confining conditions" (Kirchheimer) for rational political choices provided by the circumstances of present-day politics.

This paper is based on intensive study of the contents of the journal “Raumforschung und Raumordnung” (RuR) – from its first publication in 1936 to its (temporary) discontinuation in 1944. It was the forum for the new scientific and political thoughts and reflections that were formed in this field during the Nazi era and was supported by the institutions in charge of its publication: the “Reich Association for Spatial Research” (RAG) and the “Reich Agency for Spatial Planning” (RfR). The aim of the paper is to uncover which social developments and accompanying intellectual groundwork from the time before 1933 the authors were able to build upon, both positively and negatively, and which expositions paid tribute to the (malevolent) spirit of the times and the goals of the Nazi regime. The contradiction between professional competence and intellectual subservience to the Nazi regime, or even the perversion of professionality, is revealed in the career behaviour of academics and practitioners, almost all of whom were born around 1900. Their activities after 1945 and their future careers are mentioned but are not the subject of this paper.

In this article, the history of emigration from Germany and the immigration to Germany especially in relation to its changing borders in the 20th century is discussed. After 1945 Germany was confronted with the integration of a million German refugees. Starting in the 1950s, Germany intentionally attracted foreign workers, and integrated them fairly well. The article analyses the current discussions in Germany in relation to the impact of massive immigration of refugees from non-European areas around 2015. It concludes with a position that in the time of globalisation migration needs a society-focussed and political learning process which has not yet ended and will require more learning. But countries with a declining population are well advised to see immigration as an opportunity for future growth and social diversity.
