Abstract

In writings published after the Second World War, Martin Heidegger reinterpreted the ontological concepts by means of which he had characterized human existence in Sein und Zeit (1927), and he claimed that his new definitions revealed the real meaning of these “existentialia.” One might wonder what justifies or explains Heidegger’s surprising procedure. According to the solution to this problem proposed here, Sein und Zeit and the later works belong together as the two stages of a unified grand strategy of religious apologetics.
