This paper argues that there is a strong role for empirical analysis to be used to address fundamental normative questions. Using human rights as an example, the article shows that the evolution of the international regime of human rights provides a standard against which country level performance can be both judged and explained through the application of empirical approaches in comparative politics. It argues further that different kinds of human rights measures (events, standards, surveys, and official statistics) and comparative methods (large-N, small-N and single-country studies) offer systematic ways in which to map, explain, and understand the variation in human rights abuse around the world. In this way, the comparative politics of human rights is prime example of how the 'is' of the world can be used to address the 'ought' of international human rights theory, philosophy, and law. The example of human rights analysis in comparative politics shows a strong role for value-based and problem-based research that remains systematic in its approach while at the same producing outputs that are of public value.1
IntroductionIn late 1989, I was working in the photographic laboratory in the Lauinger Library at Georgetown University when a Jesuit Priest arrived one morning with a roll of film that he wanted us to develop. He asked that we make ten copies of the pictures on the roll. In those pre-digital days, my boss and I stood in the darkroom shaking the can, drying the film, and then printing the pictures. We were not prepared for what we were about to see. The pictures had been smuggled out of El Salvador and were of the scene at the Pastoral Centre of José Simeón Cañas Central American University (UCA) where six Jesuit priests along with a maid and her daughter were killed. 1 The images that confronted us were not what was reported in the mainstream press (i.e. that they were simply shot). Rather, we saw the brutal end results not only of a 'simple' set of extra-judicial killings, but the result of a manner of killing that has left an indelible mark on me ever since. The official truth commission in El Salvador presented strong evidence that not only had the military given the orders to carry out the murders but that the officers involved also engaged in a cover up. 2 The facts of the case and the images that I developed those many years ago illustrate a basic point about the enduring capacity of human beings to do horrible things to one another, which for me led to the deontological conclusion that what I saw was morally wrong and which has galvanised my commitment to a lifetime of human rights research.In 2000, I found myself in João Pessoa, the Eastern most tip of South America for lectures and a field visit to the contested countryside in the state of Paraíba, which is dominated by agriculture and the production of leather. Our field visit was to the sugar cane fields to the West of João Pessoa to meet with officials of the Comissão Pastoral da Terra (Pastoral Land Commission, CPT) and activists f...
