The process of liberation is a movement toward greater diversity, interiority, and communion. At the social level, liberation celebrates differences and dialogue while renouncing monoculture. Liberation’s method recognizes spirituality and relationality, both of which can deepen through humanity’s conscious participation. Today, we see the liberation process in movements for social justice, animal rights, and climate activism, among others. In this article, I interpret Martin Luther King Jr.’s worldview and influence during the 1960s through the lens of integral philosophy, as recently expanded by the new political philosophy of post-progressivism. I critically examine how King’s example can inform cultural intelligence in liberation activism today.
