Phenomenological philosophizing is practiced out of a sense of responsibility for contemporary culture, which is experienced as existing in a profound crisis. The first part of this contribution contains a systematization of the theory of crisis, a theory developed in many of Husserl’s works: the description of the main phenomena of the consciousness of crisis, the explanation of crisis with regard to its causes, and the demands raised in order to overcome the crisis of scientific culture (»reflection«). Husserl’s teachings on crisis are placed into close relation with his idea of science and science’s Greek origin, an origin from which, according to Husserl, modern science has tragically distanced itself. It is argued, however, that Husserl was not at all a philosopher of decline or decay. The second part of this contribution represents an attempt to provide a critical and complex answer to the question as to the modern relevance and usefulness of Husserl’s theory of crisis.
