Q

what does Anselm say is the logical contradiction regarding God?

A

if God is greatest thing we can think of and he does not exist, would not be greatest thing we can think of, a real thing is greater as it is more real

Q

how did Guanilo use a perfect island to critique Anselm?

A

imagine an island with abundance of all good things, greatest conceivable island, with Anselm’s logic this island must exist in reality- but does it???

Q

how did Guanilo use people’s ideas of island to critique Anselm?

A

all people have different ideas of the perfect island in their mind, therefore the greatest conceivable island cannot exist in reality as it would not be the greatest conceivable island for everyone

Q

how did Descartes use a triangle to support his argument?

A

just as absurd to think of a perfect being that did not exist as it was to conceive of a triangle without 3 sides or angles. It is the nature of the triangle to have 3 sides, nature of God to exist

27
Q

what does Anselm argue the unbeliever must have?

A

a definition of God in order to dismiss it as a concept

28
Q

what are reductio ad absurdum arguments?

A

begin with a proposition and attempt to prove through logical reasoning that it would be absurd to reject the proposition

29
Q

what is Descartes argument simple terms?

A

1.God = supremely perfect being
2. existence is a perfection
3. illogical to think of concept of God without concept of existence

30
Q

what does Kant argue existence is not?

A

a predicate, it is not a quality in the same way red and large are

31
Q

how does Kant use his analogy of 200 pounds to support his argument?

A

if i have 200 existing pounds and 200 imaginary pounds the idea of pound stays exactly the same whether it exists or nkt

32
Q

what does Kant argue God is not?

A

an exception to the rule- all the argument does is provide a definition of God to see whether the world might have such a being who could fulfil the criteria

33
Q

what must a predicate do according to Kant?

A

give us information about X, saying ‘X is’ gives us no information

34
Q

what is the Proslogian?

A

prayer written by Anselm looks at nature of God from a number of different aspects

35
Q

if a definition or concept of God exists in everyone’s minds, what does this show/ lead to?

A

everyone has concept, God must exist in reality too, existence in both mind and reality needed for God to be greatest conceivable being

36
Q

what is De Dicto?

A

relating to the form of an assertion or expression itself, rather than any property of a thing it refers to

37
Q

what is De Re?

A

relating to the properties of things mentioned in an assertion or expression, rather than to the assertion or expression itself

38
Q

what does Guanilo argue using De Dicto and De Re?

A

you cannot define God into existence moving from the idea De Dicto to assuming it’s existence in reality De Re

39
Q

what is Anselm’s 2nd Formulation, defending against Guanilo?

A
  1. Island is contingent + changing
  2. any contingent thing can be conceived as not-existing
  3. a being than which nothing greater can be conceived cannot not exist
  4. Gods existence is necessary
40
Q

who says existence is a predicate of perfection?

A

Descartes

41
Q

what 2 types of necessity does Malcom argue there are?

A

logical necessity and factual necessity

42
Q

what is logical necessity?

A

it is illogical to suggest that something is the case, statements which are analytical rely on logic for meaningfulness

43
Q

what is factual necessity?

A

it is provably wrong to suggest that something is the case, statements which are synthetic rely on empirical evidence for meaningfulness

44
Q

what does Malcom say about Gods existence?

A

if God is greater possible being and does not exist, he cannot come into existence

45
Q

why does Malcolm argue God can’t come into existence if he doesn’t exist?

A

he has necessary existence, he cannot be cause to come into existence

46
Q

what is Malcom’s argument?

A

1.God GPB, if doesn’t exist cant come into existence
2. God has necessary existence
3.God either always existed or will never exist
4.If God exists his existence is necessary
5. Existence cannot be impossible- self contradictory, so God necessarily exists

47
Q

how does Malcom misuse the word impossible?

A

uses it to mean something cannot be true because of a matter of fact and also to mean something logically contradictory

48
Q

what does Malcom’s argument only do?

A

show that Gods existence is necessary IF God exists, not that God actually exists

49
Q

how does Guanilo use empiricism to support his criticism?

A

there are no example of perfect things in the world, no perfect pen, book etc but if things are perfect they must exist otherwise it is a contradiction to call them perfect

50
Q

what does Anselm say about fouls and understanding?

A

they do not understand the concept of God, they say the words there is no God or God does not exists but this is a result of them not truly comprehending the concept of God

51
Q

what is a defining predicate?

A

a description that is necessary to the concept

52
Q

what is Descartes’ quote?

A

I cannot conceive a God without existence

53
Q

what does Kant argue there is not contradiction in doing?

A

rejecting a concept together with all its predicates e.g you can accept being half woman and half fish is a defining predicate of a mermaid but you aren’t contradicting yourself by saying you don’t believe in mermaidw

54
Q

what does immutable mean?

A

incapable of change/being different

55
Q

what does Plantiga say about Kant’s criticisms?

A

they are limited in refuting the ontological argument, must show where the argument goes wrong by identifying a premise that makes a mistake

56
Q

how did Kants empiricism influence his criticisms?

A

believed statements about god must be synthetic and be proved through experience, Gods existence cannot be proven using reasoning

57
Q

what philosophers support the OA?

A

Anselm, Descartes, Norman Malcom, Plantiga

58
Q

what philosophers reject the OA?

A

Kant, Aquinas, Guanilo, Bertrand Russell, Gottlob Frege, Hume

59
Q

what does Aquinas say about the OA?

A

-we don’t have agreed definition of God so can’t say he is greatest possible being
-can’t know Gods nature, only reason to what Gods like through experience

60
Q

what does Bertrand Russell say about the OA?

A

-existence not a predicate- not property of things but idea of things
-Anselm used word exist incorrectly
-existence = extension of intention- describing something

61
Q

what does Plantiga say about the OA?

A

there is infinite no. possible worlds- one world with max greatest being- can only have max greatness if exist in all worlds- God must exist in our world

62
Q

what does Frege say about the OA?

A

-1st order predicates tell us something about nature of something
-2nd order predicates tell us about concepts
-Anselm and Descartes use existence as 1st order predicates when actually 2nd order predicate

63
Q

what does Hume say about the OA?

A

cannot define something into existence, only way to find out if something exists to look for evidence outside thing itself

64
Q

what are 3 strengths of the OA?

A

a priori-no uncertainty regarding sense experience
deductive-seeks to provide definitive proof of existence of God
logic- uses reason + logic

65
Q

what is an analytical statement?

A

a statement which it is ridiculous and impossible to think is false

66
Q

what is a synthetic statement?

A

a statement in which the statements truth or falsity depends on evidence which has to be collected

67
Q

what is a predicate?

A

a quality or property of an object or subject
