ABSTRACT
In this chapter, we shall return to issues of a foundational-philosophical nature, where we address important questions about the nature of scientific theories in light of the developments made in the previous chapters. Questions concerning the nature of scientific theories are a constant presence in the philosophy of science, and as we saw in chapter 1, the debate on the precise nature of the semantic approach has recently reappeared. Our main aim is to explore the consequences that the specific framing of theories as exposed in the previous chapter may have when we deal with models, languages, and the general structure of scientific theories. The investigation will proceed at the metalevel.
