This thesis aims to analyze German Conservatism and the impact of Germany&rsquo / s policies towards Turkey&rsquo / s membership. The point of departure is privileged partnership which is offered to Turkey in replace of membership to the EU. German Chancellor Angela Merkel is a prominent defender of privileged partnership and previous Chancellor Gerhard Schr&ouml / der who supported Turkey&rsquo / s accession, had a totally different attitude. It is questioned whether this sharp change in foreign policy derives from German Conservatism and Christian Democracy. As a result, it is not possible to claim an essentialist opposition to Turkey&rsquo / s accession by German Christian Democrats but privileged partnership is a product of German Conservative thinking which sees European Integration as a cultural project.

Notre thèse étudie la position et la fonction qu’occupa le philosophe Erich Rothacker (1888-1965) dans le champ philosophique et scientifique allemand de son temps. Elle retrace l’évolution de sa politique intellectuelle de la République de Weimar à l’après-guerre, évolution qu’il faut lire comme un processus de redéfinition de son historisme conservateur face aux contextes historiques successifs. Tandis que son activité sous la République de Weimar fut guidée par sa volonté d’imposer un paradigme d’historisme polémique et idéologisé, l’avènement du national-socialisme l’a conduit, après une phase d’étroite adhésion, à redéfinir cet historisme, qui devint progressivement (et non sans quelques ambiguïtés) un simple paradigme épistémologique désidéologisé. C’est au terme de cette évolution que Rothacker put influencer dans l’après-guerre la réflexion de certains de ses étudiants devenus par la suite célèbres, tels Jürgen Habermas, Karl-Otto Apel et Hermann Schmitz. Outre qu’elle répond à plusieurs questions jusqu’à présent en suspens dans la littérature secondaire sur Rothacker (relatives à son rapport au nazisme, ou encore au rôle – éminent mais paradoxal – qu’il joua au sein du champ théorique de son temps), notre étude de sa politique intellectuelle met ainsi en évidence deux phénomènes qui dépassent le cadre de son analyse stricto sensu : le mouvement – commun à plusieurs penseurs – de radicalisation puis de déradicalisation du conservatisme intellectuel allemand au cours du 20ème siècle, et l’existence d’une ligne de continuité souterraine de la pensée historiste dans l’Allemagne de l’après-guerre en dépit de l’ostracisme dont cette tradition faisait alors l’objet. / Our dissertation investigates the position in, and function of, the german philosopher Erich Rothacker (1888-1965) within the philosophical and scientific fields of his time. It traces the developments in Rothacker’s intellectual politics from the Weimar Republic into the post-war world – a development that can be interpreted as a process of redefining his conservative historicism within the framework of changing historical contexts. While his work was guided by the aim of promoting a polemic and ideologised paradigm of historicism at the time of the Weimar Republic, Rothacker, faced with the national-socialist regime, subsequently redefined this historicism after a period of enthusiastic endorsement with the National-Socialists. Rothacker’s historicism thus gradually developed (though not without remnants of ambiguity) into a purely epistemological paradigm, stripped of all ideology. As a consequence of this development Rothacker succeeded in the post-war era in influencing the thought of several of his students who were to become well-known intellectual figures, such as Jürgen Habermas, Karl-Otto Apel and Hermann Schmitz. Besides offering answers to some questions concerning Rothacker that remain unanswered in critical discourse to this day – such as his relationship to Nazism, or his role within the theoretical field of his time – our analysis provides a picture of two phenomena transcending Rothacker’s own person: the deradicalization of German intellectual conservatism in the course of the twentieth century, and the persistence of historicist thought in post-war Germany despite the ostracism that this tradition was subjected to in the decades following the war.
