Philosophy of law as a branch of philosophy that focuses on profound questions about
law, is greatly influenced by three main components in philosophy, namely ontology,
epistemology, and axiology. These three components play an important role in understanding
the development of legal science and in solving empirical legal problems.
1. Understanding the Development of Legal Science
Legal ontology is related to understanding the nature of law itself, whether law is
something objective and exists separately from society or whether law is only a social
construction formed by human consensus. The main questions in legal ontology are “What is
law?” and “How does law exist?” In the development of legal science, ontology functions to
explore how law develops along with social, cultural, and political changes in society. Law can
be seen as a stand-alone entity, or as a reflection of the values and social agreements that live
in a community. For example, changes in the concept of human rights reflect how society's
views on individual rights change, which affects legal norms. Therefore, legal ontology helps
us to understand the dynamics and changes in law along with the development of the times and
social needs.
Legal epistemology is related to the ways in which we gain knowledge about law, as
well as questions about legitimate sources and methods in understanding law. Can law only be
understood through written legal texts, or does our understanding of law also involve social
interpretation, judicial decisions, and other legal practices? In the context of the development
of legal science, epistemology plays an important role in exploring how law is studied,
interpreted, and applied in various legal systems. Understanding epistemology helps to critique
various approaches to studying law, whether through formal texts such as statutes or through
developing social practices and customs. For example, the application of judicial interpretation
often shows that understanding the law depends not only on written texts, but also on the social
context and values that exist in society. Legal epistemology allows us to be more critical of the
methods and sources of knowledge used in different legal systems.
Legal axiology focuses on the values contained in the legal system and how these values
influence the formation and application of law. This includes questions about whether the law
aims to achieve justice, common welfare, or other ethical values in society. In the context of
the development of legal science, axiology encourages us to evaluate whether existing legal
norms reflect the moral and social values desired by society. For example, in the criminal
