This article is exploratory in nature and attempts to address the following two questions: What is the role of abstractions in sociology? and How can you learn to become better at using them? Noting that there exists next to no literature in sociology on the topic of abstraction, a presentation is first made of two statements on this subject by Durkheim and Weber. Their content can be summarized as follows: abstractions are produced through isolation and generalization. Durkheim and Weber, like other sociologists, do not, however, address the issue of the general nature of abstraction, and for this, some ideas by Charles S. Peirce and Alfred North Whitehead are brought in. They suggest that an abstraction is characterized by the fact that its nature is derived from the reality of another phenomenon. The consequences of this view for sociology are discussed. The article ends with an attempt to show what a practical definition of abstraction would look like, in which the focus is on how to construct and use an abstraction, rather than on just define it in a formal manner.
