 Dougherty and Callender (2019) have challenged orthodoxy here, as well, by arguing that the many ways in which the area of a black hole does not behave like classical entropy strongly suggests that we should be skeptical of treating it as such. Curiel (2017b, Other Internet Resources) attempts to rebut them using exactly the idea that any extension of a known physical quantity into a new regime will inevitably lead to modifications of the concept itself, and emendations in the relations it may enter into with other physical quantities. Thus, we should expect that black-hole entropy will not behave like ordinary entropy, and it is exactly those differences that may yield physical and philosophical insight into old puzzles.
