The document discusses several major thinkers and their impacts on theology, including Darwin and his theory of evolution challenging biblical authority; Marx arguing that ideas are products of economics rather than causes; Foucault examining power/knowledge and regimes of truth; Lyotard declaring the death of metanarratives; Levinas prioritizing ethics and the relationship to the other; and Derrida deconstructing logocentrism and the privileging of presence over difference. Theology after these thinkers grapples with rethinking core doctrines like anthropology, Christology, and soteriology through constructive engagement with these challenging perspectives.
