Imagining Human Rights (publ. by De Gruyter, 2015)
https://www.amazon.com/dp/B016GJCFTW...ing=UTF8&psc=1
"Why are human rights considered inviolable norms of justice although more than hundred countries around the globe violate them? This paradox seems reducible to the discrepancy between idealism and reality in humanitarian affairs, but Imagining Human Rights complicates this picture by offering interdisciplinary perspectives on the imaginary status of human rights – on their power and limitation alike."
I just finished this and IMHO its definitely worth reading if you're
interested in the topic and don't mind academic style writing.
