A Review of the Habilitation Thesis by A. V. Yampolskaya «Phenomenological Method and Its Limits: from German to French Phenomenology» (Prepared by A. Patkul) According to Yampolskaya, the main methodological difficulty of phenomenology is the uncertainty of the correlation between the method and the object. This uncertainty reveals ambiguity in the interpretation of the concept of phenomenon. These basic difficulties encountered by the German phenomenology of Husserl and Heidegger have brought to life French phenomenology. Yampolskaya suggests that the key feature of French phenomenology is that it expresses less interest in the problem of reduction and more interest in different components of phenomenological method. Unlike German phenomenologists, who consider phenomenology to be the description of the evident, French thinkers see phenomenology as a description of concealed.
