The
Laws of Manu (also known as the Manusmriti or
Mānava-Dharmaśāstra) is a Hindu text that covers juridical and spiritual matters. It’s been used to justify the caste system, as Nietzsche outlines in this passage. Chandala refers to a Hindu lower caste. Nietzsche here evokes the caste system as outlined in the
Laws of Manu to illustrate how religion uses morality to justify (and directly contribute to) human suffering.
