 Reichenbach’s fork asymmetry has been subjected to numerous criticisms. Horwich (1987) argues that our willingness to infer a past interaction often has little to do with entropy. We may infer from a pile of rubble that a city has been bombed. A pile of rubble corresponds to higher entropy than intact buildings; but it is the former, rather than the latter, that leads us to infer that a certain kind of interaction with the city has taken place.
