(in English) This thesis focuses on the life of Ferdinand Hildprandt and the development of the town Blatná at the time of his life. Ferdinand Hildprandt, who lived between 1863 and 1936, was a nobleman and a member of house Hildprandt von Ottenhausen, the owners of the castle Blatná. He also owned the neighboring homestead and plenty of ponds, forests and fields. He was a district mayor from 1914 to 1919. He strived for prosperity, development and economic growth of the town. He supported education, established a fund for the poor and he built an orphanage. The most important step was the construction of a railway which connected Blatná and the surrounding world. This led to the increase of population in Blatná as well as to major developments in the industry. Hildprandt was active in politics, too. He was a member of the local assembly and a defender of Czech historical law. The focus of this thesis primarily lies on the House of Hildprandt itself. It mostly focuses on the life of Ferdinand Hildprandt in particular, on his attittudes, opinions in the period of Habsburg monarchy and the so-called First Republic. Furthermore, it also revolves around cultural history of the period.

La sexualité est arrivée au statut d’objet scientifique à la suite des découvertes psychanalytiques. L’élargissement du sexuel avec Freud par la théorie de la libido a permis une investigation beaucoup plus large et complète de la sexualité, la faisant apparaître comme un phénomène de totalité. Les sciences sociales n’ont pourtant pas nécessairement intégré cet élargissement dans leurs théorisations sur la sexualité livrant une définition de celle-ci selon leurs paradigmes et cadres interprétatifs disciplinaires. De même, la politisation de la sexualité a dans un premier temps interpréter la question de la libido freudienne dans une utopie critique, celle de la libération sexuelle de Mai 68. Dans un second temps, elle a idéologisé et partialisé la question sexuelle en orientant les débats sur les questions des minorités sexuelles. La démarche critique adoptée dans cette thèse permet de montrer en quoi la sexualité en tant qu’objet est l’analyseur des sexualités concrètes. La sexualité est une force originaire au fondement de la subjectivité, de l’intersubjectivité et des formations sociales. Elle ne peut donc être conceptualisée de façon réductrice. Cette complexité est nécessairement polémique car elle comprend des enjeux épistémologiques, politiques, mais aussi éthiques, praxéologiques et métaphysiques. / Sexuality become a scientific object following psychoanalysic discoveries. The extension of sexuality by Freud with the libido theory allow more complete and broader investigation of sexuality, showing it as a phenomenon of totality. Social sciences however did not insert this enlargement into their theorizings on the sexuality delivering a definition of this one according to their paradigms and disciplinary interpretative frames. Also, the politicization of sexuality has at first interpreted the question of freudian libido in a critical utopia, that of the sexual liberation of Mai 68. In second time, it has ideologised ans partialised the sexual question by orientating the debate on the sexual minorites questions. Critical step adopted in this thesis allows to show that sexuality as object is the analyser of concrete sexualities. Sexuality is a native force in the foundation of subjectivity, intersubjectivity and social trainings. Sexuality can’t be conceptualised in a reductionnist way. This complicacy is necessarily polemical because it consists in epistemological and political stakes, but also in ethical, praxeological and metaphysical stakes.
