Belief (of being) in Husserl’s phenomenology counts without question to his central theme of perception, phantasy, and consciousness of time and it remains in a close context with them. This work tries to explain these problems and to point out how far these questions have been solved by Husserl and which questions still need further research. Moreover, the reasons for the success or failure of Husserl’s efforts need to be examined. The first part of the book, chapters one to four, provides the structure analysis of the belief from different aspects and deals stepwise with Husserl’s exposition of different directions of the belief, modalities, and modifications as well as the authenticity and inauthenticity of the belief. The second part, chapters five to eight, refers to the different ways of the suspension of the belief that the main theme is constructed; the eidetic reduction, the neutrality-modification and the transcendental reduction.
