The Doctrine of the Concept and Modern Legal Studies

In modern legal research, outdated logical information is actively used. The paper shows that traditional logic, in general, is not capable of an adequate analysis of concepts and relations, which sharply narrows its possibilities. In the course of the study, it was found that any concept is not a thought about an object, but a property or relation, i.e., an n-local predicate. Therefore, the division of concepts into concrete and abstract ones is meaningless. The idea of the content of a concept is the weakest point of traditional logic, because questions about the composition of the content and the number of features of the content are not even raised. The paper proves that the content of any concept is always an infinite set of formulas (signs). Since the volumes of concepts can contain any number of elements, there is no quantitative relationship between the volume and the content of concepts, which is not a criticism of the law of the inverse relation, but its denial. The analysis of the doctrine of the concept carried out by means of modern logic significantly expands the possibilities of both everyday and scientific practice, in particular modern legal research.
