Upholders of fictionalism about scientific models have not yet successfully explained how scientists can learn about the real world by making comparisons between models and the real phenomena they stand for. In this paper I develop an account of model-world comparisons in terms of what I take to be the best antirealist analyses of comparative claims that emerge from the current debate on fiction.

Science provides us with representations of atoms, elementary particles, polymers, populations, genetic trees, economies, rational decisions, aeroplanes, earthquakes, forest fires, irrigation systems, and the world’s climate. It's through these representations that we learn about the world. This entry explores various different accounts of scientific representation, with a particular focus on how scientific models represent their target systems. As philosophers of science are increasingly acknowledging the importance, if not the primacy, of scientific models as representational units of science, it's important to (...) stress that how they represent plays a fundamental role in how we are to answer other questions in the philosophy of science. This entry begins by disentangling ‘the’ problem of scientific representation, before critically evaluating the current options available in the literature. (shrink)

According to Millianism, the meaning of a name is exhausted by its referent. According to anti-realism about fictional entities, there are no such entities. If there are no fictional entities, how can we explain the apparent meaningfulness of fictional names? Our best theory of fiction, Walton’s theory of make-believe, makes the same assumptions but lacks the theoretical resources to answer the question. In this paper, I propose a pragmatic solution in terms of two main dimensions of meaning, a subjective, psychological (...) dimension and an intersubjective, public dimension. The psychological dimension builds on the notion of mental files; the public dimension builds on Stalnaker’s notion of common ground. The account is coherent with two main theoretical principles, parsimony and uniformity. Furthermore, it satisfies three explanatory conditions posed by the intentionality of our thought and discourse about fiction, object-directedness, counterfictional imagining and intersubjective identification.

In this entry I will offer a survey of the contemporary debate on fic- tionalism, which is a distinctive anti-realist view about certain regions of discourse that are valued for their usefulness rather than their truth.
