God and Evil Flashcards
(30 cards)
What is a theodicy (according to Alvin Plantinga)?
A theodicy is an explanation for the existence of evil in a universe containing an omnipotent and perfectly good being.
E.g. God prefers a world in which evil is overcome by good, to a world in which there is no evil.
What is a defence (according to Alvin Plantinga)?
A defence is merely a demonstration that a set of propositions are logically consistent.
To show that a set of propositions (p) and (q) are logically consistent, it is sufficient to find a proposition (r) that is logically possible (not-self contradictory) and which is consistent with (p) and together with (p) entails (q).
It is not necessary to show that (r) is true of even plausible.
How does Plantinga conceptualise a possible world?
A possible world is a maximal possible state of affairs. That means for every world w, and every proposition p, either p is true in w or p is false in w.
There are many propositions that are true in the actual world that God does not make true by the creation. E.g. God exists, God is perfectly good, God is omnipotent, and many others pertaining to God himself.
God does not bring about an entire possible world, just a part of it.
The part that God brings about he strongly actualises.
What is the distinction between what God strongly actualises and what He weakly actualises?
Suppose that part of what God brings about is the existence of free creatures, and those free creatures make certain propositions true through their actions, for example, the proposition ‘Eve eats the apple’.
There is an indirect sense in which God brings about the truth of this proposition through creating Eve and giving her free will- but Eve brings about the truth of the proposition directly.
In Plantinga’s terminology, God weakly actualises ‘Eve eats the apple’ and Eve strongly actualises this proposition.
What God weakly actualises is what He actualises through free creatures whom He has created and to whom he has given free will.
What might be some true propositions in the world?
(A) Adam and Eve live in the Garden of Eden and have free will.
(B) Adam and Eve eat the forbidden fruit.
(C) If God created Adam and Eve, they would eat the forbidden fruit.
God strongly actualises (A) and weakly actualises (B) and (C).
Other propositions follow from what God has strongly actualised and counterfactuals of freedom.
How does our world w1.1 get actualised?
If the actual world is world w1.1, let us call the part of the world that God strongly actualises world germ w1. The entire history of w1.1 is the product of what God strongly actualises and the true counterfactuals of freedom in w1.
There is another true proposition.
(F) If God strongly actualises world germ w1, world w1.1 would be weakly actualised. Unfortunately, there is evil in w1.1.
How does is the notion ‘transworld depravity’ relevant?
Suppose further that no matter what God strongly actualises, the world that results would have evil if it had free creatures in it.
If this is the case then all possible free creatures suffer from transworld depravity.
How does Plantinga set up the logical problem of evil (borrowed from Mackie)?
(1) An omnipotent and perfectly good being (God) exists
(2) Evil exists
There seems to be a logical contradiction between (1) and (2)
How does Plantinga solve the logical problem of evil?
(3) No matter what God created, if it included free creatures, evil would result.
As long as (3) is logically possible, is consistent with (1) and together with (1) entails (2), the compatibility of (1) and (2) has been demonstrated.
Suggest some further remarks here about how Plantinga has solved the problem of evil.
The world germ that God creates will result in a world that is at least as good as any that would result from any other world germ that God could create instead.
Plantinga is not committed to the claim that the actual world is the best possible world.
Nor is he committed to the claim that any world with free will in it is better than any world without free will, as Mackie interprets the free will defence. E.g world w2.9 may be worse than a world without free creatures.
But as long as it is possible that w1.1, the actual world is better than any world without free creatures and is at least as good as the world that would be weakly actualised if God were to create a different world germ instead, the Free Will defence succeeds.
How does Plantinga’s defence lead us to the evidential problem of evil?
Plantinga solves the logical problem of evil. His defence shows that evil is compatible with a perfectly good and omnipotent God. However, we may still ask the question of whether (3) is plausible. This leads us to the evidential problem of evil.
What is the conclusion of the evidential problem of evil?
The existence of God is improbable, given the existence of evil.
Why is the evidential problem of evil harder to answer?
- A defence is not sufficient. Even if (3) is logically possible, if it is improbable, the evidential problem of evil has not been solved.
- Proponents of the evidential problem tend not to formulate their argument in terms of evil in general, but rather point to specific instances of evil.
What is the example that William Rowe uses (1979)?
A fawn burning slowly to death in a forest fire.
How does Rowe argue that this fawn burning to death slowly makes the existence of God unlikely?
He does not argue that it is logically incompatible with an omnipotent and perfectly good God. Rowe concedes that such a God might have a reason. Nonetheless, we are justified in thinking that there is probably not such a reason. Consider all angles and probable consequences. Consider how likely that some good will come of the incident.
What is more likely, that there is a God or there is not a God? Rowe would argue the latter. The fawn’s suffering is evidence against the existence of God, even if it is not a definitive proof.
What is a gratuitous evil?
A gratuitous evil is one for which we are justified in believing that there are no countervailing goods that cannot be obtained without the suffering.
How does Stephen Wykstra criticise Rowe’s argument?
It is a fallacious argument from ignorance. Just because you do not see something does not mean that it is not there.
The problem is that sometimes when you do not see any evidence for the existence of something, it is probable that it does not exist, but other times you are in no position to say that it probably does not exist.
What is an example that illustrates this difficulty with the reasoning of the evidential problem?
Suppose you look around your recently cleaned out garage and do not see a dog. You are justified in believing that there is no dog.
However, suppose that you look around your garage and you do not see any fleas. You cannot justifiably conclude that there are no fleas in the garage. The reason is that the garage would look the same to you whether there are fleas or not.
So lack of evidence for p may or may not be evidence of not p.
What is the ‘Requirement of Detectability’?
When we do not have evidence for the existence of R, we are entitled to believe “R probably does not exist” only if it is more likely than not that if R existed, we would be able to detect R.
What result does the Requirement of Detectability yield when applied to the evidential problem of evil?
Given the infinite difference between human cognitive abilities and divine purposes on the hypothesis of traditional theism, there is no reason for us to expect to be aware of God’s reason for permitting suffering, even if there is one. As a result, we are not justified in believing that God’s reason for permitting the fawn to suffer probably does not exist.
What are some issues with using RD to respond to the evidential problem of evil?
One problem is that if we take the view that it is unlikely that we would detect a reason justifying God in permitting evil if there was one, this threatens to make theism unfalsifiable in an important way. A theory is unfalsifiable if it is compatible with all observations (i.e. incapable of disconfirmation). It is generally thought that a theory is defective if it is unfalsifiable.
Another problem with RD comes from a consideration of the Cartesian demon. Compare the hypothesis of an evil genius who is always fooling you about the existence of an external world with the hypothesis that there is no evil genius and there is an external world that is more or less the way that you think it is. The world would look the same to you either way. But RD tells us that we are justified in believing an evil genius does not exist only if it is more likely than not that if an evil genius did exist, we would be able to detect it. But of course we would not, according to the standard skeptical hypothesis. So RD seems to pave the way for global skepticism.
How does Mackie set up the logical problem of evil?
(1) God is omnipotent
(2) God is wholly good
(3) Evil exists
The contradiction arises when we supplement these propositions with another couple of principles. Good is opposed to evil, in such a way that a good thing always eliminates evil as far as it can. There are no limits to what an omnipotent being can do.
What are the adequate solutions to the problem of evil?
These solutions deny one of the propositions.
Does Mackie accept the qualification that omnipotence does not require the power to do what is logically impossible?
Yes, he does accept it, as it does not dispense with anything essential to theism. (There are still theological problems with accepting that God is bound by logic though).
