Title: Ramsey Meets Ptolemy: Perspectivism about Theory Change
Abstract: A Ramsey-sentence is defined as an existential sentence that is equivalent to a scientific theory. In this talk, I use the Ramsey-sentence approach to argue that past theories can contain truthful content. I begin by reviewing its applications in the work of structural realists and David Papineau before outlining my own use of the approach. I then apply it to explain the success of the Ptolemaic model in predicting the positions of the outer planets. Finally, I draw lessons about theory change in the history of science, offering a perspectivist interpretation.ent phenomena and provide a robust framework for understanding their place in the ontological structure of the universe.
