Hegel's explanation of master and slave has become important in many fields of study. Some examples are in social sciences, discourse analysis, and psychoanalysis. The American researcher David Duquette says the more correct name in English for this philosophy is "lordship and bondage", rather than "master and slave". The American professor Robert Brandom also says that Hegel's explanation represents when duty and authority are split apart. Duties are only given to the "slave" but authority is only given to the "master". The problems of master and slave happen when people try to take one without the other.
