What is the role of bridge laws in intertheoretic relations? An assumption shared by many views about these relations is that bridge laws enable reductions. In this article, I acknowledge the naturalness of this assumption, but I question it by presenting a context within thermal physics (involving phase transitions) in which the bridge laws, puzzlingly, seem to contribute to blocking the reduction.
I benefited from conversations with Margaret Morrison, Robert Batterman, Jeremy Butterfield, Roman Frigg, Eleanor Knox, Anouk Barberousse, Cyrille Imbert, Sam Schindler, Alex Manafu, and Dragos Bagu. I am of course the only one responsible for any errors remaining.
