Joseph Raz (University of Oxford - Faculty of Law) has posted Normative Powers on SSRN. Here is the abstract:
The paper provides an analysis of normative powers as the ability to change a normative condition, and distinguishes and analyse sever types of such powers: creative (e.g. to legislate), adhering (e.g. naturalisation), directing (e.g. to pay one's tax on time). It further distinguishes basic from chained powers and offers an account of the relations between the different types and the values which explain and justify their existence. It ends by showing the connection between the thesis that values depend on human nature and culture and the dependence of normative powers on justifying reasons.
Highly recommended.
