 The first thing that strikes the novice in the debate about scientific representation is that there seems to be little agreement about what the problem is. Different authors frame the problem of scientific representation in different ways, and eventually they examine different issues. So a discussion of scientific representation has to begin with a clarification of the problem itself. Reviewing the literature on the subject leads us to the conclusion that there is no such thing as the problem of scientific representation—in fact, there are at least five different problems concerning scientific representation (Frigg and Nguyen 2020: ch. 1). In this section we formulate these problems and articulate five conditions of adequacy that every account of scientific representation has to satisfy.
