Abstract

Legal positivists typically describe law as ‘thinly’ normative to distinguish it from the ‘thick’ normative force moral norms have; which legal norms may lack. One popular account of thin normativity is social normativity. But a number of scholars have offered accounts of what it is to be a thin norm that are distinct from social normativity. This paper addresses these alternative accounts of what it is to be a thin norm. It also explores whether law counts as necessarily ‘thinly normative’ on these accounts. I argue that some accounts of thin normativity are so generic (‘super-thin’) that they are unable to distinguish between (thin) norms and nonnormative facts and thus collapse into triviality. I also consider more metaphysically demanding accounts of thin normativity, such as the view that everything is a norm that is essentially represented by deontic modals. However, law might fail to meet the demands of these slightly thicker accounts. I thus propose a view of law as consisting in nonnormative facts (diagnostic categories) and suggest sketching accounts of thin normativity as contingent, rather than necessary, features of laws and legal systems.
