Q
karl popper n falsification
A
- greatest opponent to LP
- f= point that a proposition is scientific if one can state what evidence would prove it wrong
- this=principle of demarcation between scientific n unscientific, not the meaningful/meaningless
- if we believe science is all about proving r views to be true then we would make no progress at all
- its not for determining meaning but scientific asssertion
- he didnt deny RL has meaning, j that its not scientfiic
- things like marxism and psychiatry are meaningless because they are unfalsifiable: based on ways to prove themselves true, not false.
- a claim/belief is falsifiable if we can imagine what would prove it false

Q
karl popper how falsification works
A
- a scientist proposes a hypothesis
- they test it to see whether it works
- there may be many reasons why it seems to work but one occasion when it does not work is enough to disprove the hypothesis
- no general theory can be proven but it can be disproven
- we can test general statements by testing for things that work against it
- criticism becomes the main way we make progress
- eg all swans r white, we c loads ot white swans but if we see a black one then statement=false
- its a synthetically testable statement with meaning because it can be proved wrong.

Q
antony flew
A
- 1923-2010
- applied to RL
- religous ppl cant say what could prove their belief in god false, so theyre not acc asserting anything about way things r
- rl=meaningless
- it fails to assert anything about reality
- cog meaning requires expression of belief but a belief=mental representation of reality
- in order for belief to be about reality it must be falsifiable
- so even tho rl expresses belief since theyres unfalsifable beliefs rl fails to have cog meaning

Q
flew
parable of the gardener
A
- 2 ppl walk in forest n see clearing
- 1 says theres a gardener who tends to it
- other suggests waiting n see if its true
- after while believer say gardener=invisible
- so set up wire fences to try n detect him
- believer then says its a non physical gardener
- the unbeliver gets annoyed n asks flews crucial question:
- “But what remains of your original assertion?”
- religious person claims to believe in god but to protect belief from empirical testing they continually add qualifications to belief sayings its ‘not this/that’ etc
- eventually it will be nothing n ‘die a death of a thousand qualifications’.
- what is the difference between a world in which this gardener (God) exists, and a world in which it doesn’t?
- if belief in god=consistent w any possible discovery about reality then its existence makes no diff to reality.
- rl= fails to assert anything=unfalsifable n so meaningless
6
Q
flew summary
A
- All our beliefs about reality could be false (empiricism is true)
- So, a belief that cannot be imagined to be false, cannot be about reality.
- Religious belief cannot be imagined to be false.
- Therefore, RL fails to express beliefs about reality.
7
Q
flew eg of religous ppl hold to belief that god loves us like a dad loves kid
A
- flew believes amount of suffering n evil in world should falsify this as no loving dad would inflict such misery on kids
- many religous ppl continue to maintain faith in god despite suffering eg story of job, so inability to acknowledge god may not love them suggests their beliefs r meaningless

Q
flew qualification quote
A
‘die a death of a thousand qualifications’.

Q
richard dawkins
world n god
A
he pointed out that the world would be the same if there was no god, so you can see how this lines up.
10
Q
strength
The parable of the gardener strengthens Flew’s Falsificationism.
A
- even if rb appears falsifable, in cases it were tested they would edit their belief rather than admit they were wrong
- shows the ‘god the gaps’ phenomenon
- through history many beliefs have been claimed about god whcih science has over time shown false eg genesis creation story. rather than accept falsity of belief, they edit it
- so even if they say soemthing could disprove their belief we r justified in thinking that a mere pretence
11
Q
weakness: Religious belief is actually falsifiable
A
- St Paul claimed that if Jesus didntrise from the dead then faith is ‘pointless’ (1 Corinthians 15:14).
- so Christianity could be proven false if we find evidence that Jesus didnt rise from the dead, such as finding Jesus’ body.
- suggests Flew is incorrect to think RL is always unfalsifiable as there are at least some believers whose belief is incompatible with some logically possible state of affairs.
- Paul’s religious language passes Flew’s test of falsification + so would be meaningful.
12
Q
flew
evaluation defending falsification
A
- POG suggests that if we did discover jesus’ body, christians including st paul might make some excuse as to why its acc not a valid tests after all
- eg christians may be tempted to think the body is fake put there by devil
- tempting that is, it underlines flews point that theres no way to falsify belief in god
13
Q
john frame
evaluation criticizing falsifcationism
A
- john frame turns the parable on its head, w scenario where gardener=visible n claims to be royal gardener n sceptic refuses to believe that regardless of evidence
- shows flews appr fails as his belief in atheism=unfalsifiable
- atheists believe there isnt suffecient evidendce to justify belief in god
- issue=cannot say what could prove that belief false
- eg to add to his argument, if jesus appeared again or god rearranged stars to say ‘god is here’-an atheust wiuld simply say that was more likely j a hallucination, or evidence theyre in simulation
- atheism=unfalsifiable
- so falsifiability doesn’t seem a valid test for distinguishing between meaningful and meaningless language regarding religion.
14
Q
flews challenge
A
- he challenges rm hare n basik mitchell to respond to the question:
- ‘what would ahve to occur or occured to constiute for u a disproof of love of or the existence of, god?’
- hes set a trap
- if they say nothing thne their claims cannot be falsified n thus fall into his ‘nonsense’ category-theyre ‘vacous’
- so the other 2 philosphers must find a way to respond to flew that evades the trap
15
Q
RM Hare n bliks
A
- a blik=simply how u view soemthing
- ‘i must begin by stressing that, on the ground marked out by flew, he seems to me to be completely victorious’
- but he uses his own parable to suggest flews on wrong ground to understand religous assertions
