Theoretical concepts as goal-derived concepts

In this paper, I will focus on the nature of theoretical concepts, i.e., the psychological entities related to theoretical terms in science. I will first argue that the standard picture of theoretical concepts in twentieth-century philosophy of science understood them as representation-oriented common taxonomic concepts. However, I will show how, in light of recent pragmatist approaches to scientific laws and theories, several important theoretical concepts in science do not seem to fit such picture. I will then argue that these theoretical concepts should be understood instead as goal-derived concepts, since their construction and use exhibit the typical characteristics that cognitive scientists assign to goal-derived concepts. I will furthermore argue that the existence of theoretical concepts that are goal-derived concepts represents yet another example of the central role that human goals play in science.
