 While this section has focused on the Genealogy, it is worth noting that its three studies are offered only as examples of Nietzschean skepticism about conventional moral ideas. In The Antichrist, Nietzsche extended these criticisms of the specifically Christian psychological, cognitive, and evaluative foundations for morality (an extension which has been the subject of extensive recent discussion; see, e.g., Snelson 2017; Berry 2019; and the papers included in Conway 2019), and his other works criticize many other moral ideas.
