 Like existentialism, hermeneutics, phenomenology, and poststructuralism, the philosophy of liberation was never a homogeneous or monolithic movement. From its inception the philosophy of liberation was marked by internal tensions, which over time have become more intense, but that have also led to philosophical developments that have taken the original theses to new levels of refinement and theoretical elaboration. Cerutti Guldberg, who has written the most substantive and comprehensive study of liberation philosophy, has offered a typology of the internal currents that names four different currents (Cerutti Guldberg 1983, 1988–9, 2006). Beorlegui, writing more recently, argues that there are in fact six currents, though he accepts Cerutti Guldberg’s four as being the core and originating current (Beorlegui 2004: 695–727). These four currents will now be discussed sequentially.
