Abstract

Applied ontology is the attempt to put to use the rigorous tools of philosophical ontology in the development of category systems which can be of use in the formalization and systematization of knowledge of a given domain. In what follows we shall sketch some elements of the ontology of legal and socio-political institutions, paying attention especially to the normativity involved in such institutions. We shall see that there is more than one type of normativity, but that this fact that has often been ignored in standard attempts by philosophers to build ontologies of legal and other socio-political entities. In order to provide a sound system of categories for legal and socio-political institutions and entities, however, the manifold of normativity needs to be addressed. The classical examples of normative statements have been moral propositions; they do not merely describe states of affairs; they tell us how states of affairs ought to be. The distinction between how things are and how they ought to be is the basis of the distinction between fact and value. Analytic philosophers for a long time shunned discussions of normativity and ethics. They considered ethical statements as pseudo-propositions, or as expressions of pro- or con-attitudes of no theoretical significance.1 Nowadays, in contrast, prominent analytic philosophers discuss normative problems and there are important books written by such philosophers on topics such as law and justice. Here we pay attention to three seminal thinkers in this development: H. L. A. Hart, John Rawls, and John R. Searle in concerning ourselves especially with the way in which they deal with the issue of normativity. Hart is, within the context of recent analytic philosophy, the most important philosopher of law, Rawls the most..
