In the first chapter the manifold meaning of freedom is shown. In recapitulation the history of philosophical thought of freedom beginning with Epikur and the Christian philosopher Augustinus the diversification of different concepts which are developed in the course of philosophical terms of freedom have been analysed and deduced. In scientific theories, mainly in the theories of probability, is shown that the different meanings of freedom finally are founded in the anthropological forces of the mind. Whilst free will is only one form of realizing freedom in mind and action by the individual, it is also interpersonal constituted on the idea of liberty which following John Stuart Mill Freedom, thus thought in public opinion and in religious worship by the Churches, is dependent on the human rights, which must be observed to preserve general welfare.
