| contents | I revisit Roberto Torretti's "Spacetime Models for the World" [SHPMP 31 (2):171-186 (2000)] in the light of more recent work in (philosophy of) cosmology. I discuss the motivations for FLRW spacetimes as a natural starting point for inquiry, and I suggest contemporary cosmologists can avoid the rationalism that Torretti attributes to Einstein's early work in relativistic cosmology. I then discuss the senses in which FLRW models are idealized, and I show how those idealizations (and partial de-idealizations) have contributed to our understanding of the universe. |
