The law of the inverse relationship between content and scope of the concept

The law of the inverse relationship between the volume and content of a concept is the law of formal logic about the relationship between changes in the volume and content of a concept ^[1] . If the first concept is wider than the second in terms of volume , then it is poorer in content ; if the first concept is narrower than the second, then it is richer in content. For example, the concept of " physics " has a smaller volume than the concept of " science ." At the same time, the content of the concept of "physics" is more (richer) than the content of the concept of "science", since, in addition to its own, it contains all the attributes of the concept of "science".

An example of expanding the scope of the concept while reducing the content

Moscow State University → State University → University → University → Educational (Educational) Institution → Educational Establishment → Institution → Organization → Public Law Subject → Legal Entity

The law is applicable only when entering the volume of one concept into the volume of another, for example: “animal” - “dog”. The law does not work for mismatched concepts, for example: “book” - “doll”.

A decrease in the volume of a concept with the addition of new features (that is, an expansion of the content) does not always occur, but only when the attribute is characteristic of a part of the volume of the original concept ^[2] .
