Twilight of the Idols
Nietzsche uses the term "Tschandala" in the "Götzen-Dämmerung" ("Twilight of the Idols") and "Der Antichrist" ("The Antichrist"). Here he uses the "law of Manu“ with its caste system as an example of one kind of morality, of "breeding", as opposed to the Christian version of morality which attempts to "tame" man.
