You pretend that God is immutable!
But what is it that occasions the continual instability in this world, which you claim as His empire? Is any state subject to more frequent and cruel revolutions than that of this unknown monarch? How can we attribute to an immutable God, powerful enough to give solidity to His works, the government of a world where everything is in a continual vicissitude? If I think to see a God unchanging in all the effects advantageous to my kind, what God can I discover in the continual misfortunes by which my kind is oppressed? You tell me that it is our sins that force Him to punish us. I will answer that God, according to yourselves, is not immutable, because the sins of men compel Him to change His conduct in regard to them. Can a being who is sometimes irritated, and sometimes appeased, be constantly the same?
Believers like to come up with fanciful attributes and assign them to god. One of my favorites is that “god is infinite.” Well, how would a finite human know something like that? Unless god is goddy by induction (and therefore infinitely goddy) I don’t see how we don’t wind up with a sort of Hilbert’s Deity. And god is perfect! Yet, wouldn’t a perfect being have no wants or desires? (per C.S. Lewis) If god were perfect, it wouldn’t want to push us around as much as it does, since it would want nothing from us. It wouldn’t punish us for transgressions against it, either, since we couldn’t transgress against a perfect god.
God’s immutability, which Meslier attacks here, is also problematic: an immutable being would be incapable of changing its desires. So if god is happy, it would never be able to become unhappy (therefore: do whatever you want, god can’t get unhappy with you!) or if god is unhappy and immutable, god will be permanently pissed off and can never be appeased. An infinite, immutable, pissed off god: sounds like Sithrak!
I guess it’s important for god to be immutable, otherwise we could find it and kill it with nuclear weapons and free ourselves from its tyranny.
