The concept of a preferential option for the poor calls for a special attention to the weakest members of a particular society. Such an option is a challenge for the ethics of science as well. How can we pursue an "option for the poor" in the humanities? Can we do that without generating "ideologies"? This volume gives an account of these questions. Representatives of sociology, religious studies, law, economics, theology, history and philosophy try to answer this question. It is manifest that the discussion of an option for the poor is also a matter of intellectual integrity.
