The author presents the history of European thought about death since Socrates and Plato and accepts the recent stance of Levinas and Derrida. According to Hegel the life of spirit is the passing through other and other kinds of deaths. Kierkegaard claims that we can not think about absolute nothing (but we can threaten it). For Nietzsche death is the biggest truism, for Heidegger it is the most certain truth (human being is being to death) and for Sartre it is a brutal fact. Levinas and Derrida claim that thinking about death is the beginning of ethics.
