This course will explore a number of philosophical issues regarding the nature, justification, content and scope of rights. Fundamental issues include what is meant by the notion of a right, how rights are justified and what sorts or rights we have (negative and/or positive). Other issues will also be explored, including whether rights are universal or culturally determined, whether all human right, whether the scope of rights encompasses animals and ecosystem in addition to humans, and whether rights exist for groups as well as individuals.
