 Any attempt to tackle these questions faces an immediate methodological problem. As per the problem of style, there are different kinds of representations: scientific models, theories, measurement outcomes, images, graphs, diagrams, and linguistic assertions are all scientific representations, and even within these groups there can be considerable variation. But every analysis has to start somewhere, and so the problem is where. One might adopt a universalist position, holding that the diversity of styles dissolves under analysis and at bottom all instances of scientific/epistemic representation function in the same way and are covered by the same overarching account. For such a universalist the problem loses its teeth because any starting point will lead to the same result. Those of particularist bent deny that there is such a theory. They will first divide the scientific/epistemic representations into relevant subclasses and then analyse each subclass separately.
