When Nietzsche is called a radical philosopher, it is (among other reasons) because he claims to call into question what other thinkers take for granted. In the article I concentrate on the way in which Nietzsche asks his questions, and how his questions (and the vocabulary which he uses to express his questions) develop through his writings. The article points out how Nietzsche gradually discovers his guiding question and how this search reaches its climax around 1886. This guiding question turns out to be a practical or existential one: ‘To what extent can truth endure incorporation?’ (FW/GC 110 KSA 3.471).
Key-words: Question, task, Nietzsche’s development.
