Abstract
Abstract This article examines long-standing debates in moral philosophy that are relevant to international human rights law. It discusses the political conception of human rights and the four challenges to moral philosophy which include the notion that no particular religious tradition or particular comprehensive doctrine (or morality) grounded human rights and the belief that natural rights theories end up misrepresenting and narrowing the scope of human rights. This article also highlights the importance of the work of moral philosophers to the understanding of contemporary human rights and explains that the traditions of natural rights theories still influence contemporary human rights language in profound ways.
