For example, the concept of a *population*, also called a *gene-pool*, refers to a group of individuals that can interbreed. Abstract theories, like set theory, are composed of abstract concepts, like the concept of a set. The concept of a set by itself does not refer to anything. However, we cannot say that it is an empty concept, as there are countless things that can be represented by sets, for example, gene pools can be (very aptly) represented by sets of individual animals. Animal species can also be represented by sets — a set of all populations that can theoretically interbreed. -You already see how abstract theories may be useful. Because they are so simple, they can be used as building blocks of many concrete theories. Because they are common, they can be used to unify and compare different concrete theories, by putting these theories in common grounds (this is very characteristic of category theory, as we will see later). Moreover, good (abstract) theories can serve as *mental models* for developing our thoughts. +You've already seen how abstract theories may be useful.
