The concept of 'change' is theory-dependent, as different physical theories (e.g., Newtonian mechanics vs. Aristotelian physics) define change differently.

Davidson notes the heavy dependence, in Ducasse’s account, on the notion of a ‘change’. And he asks whether we really have a purchase on this concept absent appeal to laws.
