The paper discusses three talks, which were given at the meetings of the Philosophical Society of Berlin (Philosophische Gesellschaft zu Berlin) in the mid-1870s. In these talks, the principles of some main movements in contemporary philosophy (realism, absolute idealism, critical idealism) were elaborated and contrasted to each other. The paper focuses on the concepts of real-idealism and ideal-realism. All the discussants, Friedrich Frederichs, C. L. Michelet and J. H. von Kirchmann, introduce these concepts. Frederichs, an adherent of critical idealism, argues only for the standpoint of real-idealism. Michelet, G. W. F. Hegel’s personal student and an adherent of absolute idealism, takes real-idealism and ideal-realism to be the two sides of the one coin. Kirchmann, an advocate of realism, regards real-idealism as an objective, and he is skeptical about the possibility to achieve it.
