(in English): The diploma thesis "It manages better on its own": Opinions on the reliance of robots in Bohemia at the end of the pre-March period is devoted to serf duties from the Enlightenment to 1848. Legal grounding in view of several important directions of political and economic development at the end of the 18th and the beginning of the 19th century. This work analyzes biopolitical, populationist, traditionally conservative and especially liberal attitudes of politicians. And he explains why discussions on other political directions probably could not take place in Austria. It also tries to show the degree of labor duties, which was different in different states of the Austrian monarchy. Most of the work deals with the years 1840-1846. I describe the uprising in Galicia, where serf and ethnic problems were mixed. The sources were mainly the works of Jiří Štaif, Miroslav Hroch, Václav Černý and Dieter Langewiesche, but I also mention a larger number of original sources, period petitions, legal analyzes and newspaper articles. In the end, on the character of František Brauner, I show what development of thought a lawyer with knowledge of documents, social and cultural conditions could have undergone.
