Properties of Law is a legal-theoretical analysis about modern state law; about sociality, normativity and plurality as its properties, and what will come after modern state law. The main objective of this study is to offer a legal theoretical recapitulation of modern state law that avoids the fallacies of Legal Positivism. This calls for a relationist approach where law's sociality is related to normativity, and normativity to sociality. Avoiding Legal Positivism's fallacies also includes refraining from extrapolating from modern state law to law in general; replacing Legal Positivism's conceptual universalism with sensitivity to the varieties of law, and acknowledging that law existed before modern state law, that it will exist after modern state law, and that other law exists alongside modern state law. The book concludes with a discussion of the impact of digitalization on law.
