Marxian thought retains its relevance in the current period, not as a comprehensive replacement for liberal human rights theories, but as a source of critique that challenges those theories on the basis of the very values of human freedom and dignity that they espouse. The Marxian approach entails no general rejection of human-rights-oriented constraint, procedural or substantive, on efforts to achieve social change, but rather serves the human rights project by demonstrating how contradictory class interests manifest themselves as contradictions within the effort to apply liberal principles in a class-divided society.
