On the Preeminence of Euclidean Geometry: Nash’s Embedding Theorems

According to Kant’s philosophy of geometry, Euclidean geometry is synthetic a priori . The advent of non-Euclidean geometries proved this position at least problematic, if not obsolete. However, based on Nash’s embedding theorems we show that a weaker notion of preeminence supports the view that Euclidean geometry, even though not strictly a priori , enjoys a more fundamental status than non-Euclidean geometries.
