Abstract
Responsibility was always a key theme of Husserl and post-husserlian Phenomenology. This theme is related to Husserl's effort to give an answer, i.e. to offer a solution to the crisis of philosophy and the sciences. The article reconstructs the genesis and the successive development of the concept of responsibility in Husserl's work and its reinterpretation in the post-husserlian phenomenologies, especially those of Martin Heidegger, Jean-Paul Sartre, Hannah Arendt, Jan Patočka, Hans Jonas, Emmanuel Levinas, and Jacques Derrida.
