Philosophy of Religion Flashcards
God as omniscient
Omniscient means ‘all knowing’, however we must remember God is the most perfect possible being, and perhaps it is impossible to know everything. For example, if human beings have free will, then perhaps it is impossible for God to know what they will do in the future. Aquinas argues that God knows everything directly, and not through things such as language or propositions. Others argue that if God doesn’t know all true propositions then there is something that God doesn’t know.
God as omnipotent
Omnipotent means ‘all powerful’, the power to do anything. But does this include the power to do the logically impossible? Could God make 2+2 = 5?
God as supremely good
There are two ways of understanding supreme goodness. If goodness is just perfection, then saying God is perfectly good is just to say that God is perfectly perfect. The other sense of ‘goodness’ is the moral sense, in this case being supremely good means that God’s will is always in accordance with moral values.
God as eternal or everlasting
If God exists in time, then his existence is everlasting. If he exists out of time, then his existence is eternal. If something brought God into existence, God would be dependent on that thing to exist. If there were something that could end God’s existence, then God is equally dependent on that to continue to exist. If God depends on nothing else, then nothing can bring God into existence or end his existence.
The paradox of the stone
‘Can God create a stone so large that he cannot lift it?’ whether the answer is yes or no, either way there is something God cannot do, meaning he is not omnipotent.
The Euthyphro dilemma
Is morality whatever God wills it to be or is it independent of God? If morality is whatever God wills, then if God wills what is (now) morally wrong, then what is wrong will become right. If morality is independent of what God wills, then God cannot make what is wrong be right. But then, to be good. God’s will must conform to something independent of God. God wills what is morally right because it is right.
Omniscience and immutability
To be immutable is to not change. The idea that God does not change comes from the idea that God is perfect. Norman Kretzmann argues that a being that is omniscient will always know what time it is, and if it knows what time it is then it’s subject to change, therefore if its subject to change then it isn’t perfect.
Omniscience and free will
If God knows what action I will perform before I choose to perform it, then I cannot have chosen to do otherwise than I did. Therefore the actions are not freely chosen, they are predetermined. An omniscient God who knows beforehand everything that I do isn’t compatible with my free will.
The ontological argument
The argument that God, being defined as most great or perfect, must exist, since a God who exists is greater than a God who does not.
Anselm’s ontological argument
- By definition, God is a being greater than which cannot be conceived.
- This concept is coherent.
- It is greater to exist in reality than only in the mind.
- Therefore God must exist.
Descartes ontological argument
- I have the idea of God.
- The idea of God is the idea of a supremely perfect being.
- A supremely perfect being lacks no perfection.
- Existence is a perfection.
- Therefore God must exist.
Leibniz’s ontological argument
Leibniz thinks that Descartes version of the argument is incomplete as he doesn’t comprehend whether or not a being with all perfection is a coherent one. Just because we can use the expression ‘perfect being’ doesn’t mean we have a coherent idea responding to it. He argues perfections can be considered as simple and positive, meaning each cannot be defined in terms of anything else and each cannot be a negation of anything else. Each perfection is self-contained so therefore none can be shown to be incompatible with each other, and so all perfections can be collected together into one being. So if a perfect being is possible, existence is a perfection, then the rest of Descartes argument goes through and God’s existence is necessary.
Malcolm’s ontological argument
- Either God exists or does not exist.
- God cannot come into existence or go out of existence.
- If God exists, God cannot cease to exist.
- Therefore, if God exists, God’s existence is necessary.
- If God does not exist, God cannot come into existence.
- Therefore, if God does not exist, God’s existence is impossible.
- Therefore, God’s existence is either necessary or impossible.
- God’s existence is impossible only if the concept of God is self-contradictory.
- The concept of God is not self contradictory.
- Therefore, God’s existence is not impossible.
- Therefore, from 7+10, God exists necessarily.
Plantinga’s ontological argument
Plantinga sets out in establishing the idea of possible worlds. There are possible worlds where you never were born, but there are no possible worlds where squares are round since this is logically impossible. By contrast, necessary truths such as triangles have 3 sides are true in every world as these are necessary truths. Using the same ‘greater to be’ logic, he concludes that a being that exists in all possible universes is greater than one that only exists in some worlds. If we have a coherent concept of God then it follows that there must be some possible world in which he exists - however if we allow his existence in another world, since he is necessary, he must necessarily exist in our world as well.
Gaunilo’s issue with the ontological argument
- I can imagine an island which is the most excellent island.
- It is greater to exist in reality than merely in the understanding.
- Therefore, the most excellent island must exist in reality.
For Gaunilo, using an ontological argument to prove the existence of the island is always going to be in doubt until we find evidence for it.
