 Some defenders of perfect being theology have ridiculed the idea that an absolutely perfect being might be only contingently perfectly good, for even if a being were to exhibit all of the marks of perfect goodness up to a certain time, we would have no basis to think that the absolutely perfect being would not break bad at some point in the future (Rogers 2000, p. 122). But it is not clear why the contingency of the fact’s (the being’s being perfectly good) holding precludes our knowing that it holds; and it is very plausible that perfect goodness is, for God at least, what Morris calls a “stable” property, such that if God has it at some time in a world, then God has it at all times in that world (Morris 1989e, pp. 92–97).
