Abstract: What is law? The concept of legal rights is one of the most commonly defined concepts. The term law itself has several meanings and it represents the subject of study in several scientific disciplines, from legal sciences to history, sociology, philosophy, etc. Defining the term law and determining its content is not an easy task. In support of this claim, The paraphrase of the Italian legal philosopher Giorgio Del Vecchio, who claimed that everyone knows what law is, but it is difficult to define it. In legal theory, three different approaches are distinguished when defining the concept of law, so that it can be viewed as an ethical phenomenon or value system (Jusnaturalism), as a set of norms in the sense of psychological or logical-linguistic concepts (Legalism and Normativism), and as a social-material category (Socialism).
