4.2 Verification and falsification debates Flashcards
Ayer and Mitchell (33 cards)
What is logical positivism and what do they believe?
- Theory which applied principle of science and maths to language
- Believe that language can only be meaningful if it can be proved by the verification principle
- e.g the Vienna circle
Who were the vienna circle?
Group of scientists, mathematicians, and philosophers who met in Vienna in the 1920s under Moritz Schlick to debate many sybjects, most importantly, how we come to know things- called logical positivists
What is an analytic proposition?
A statement/ assertion which is true by definition
e.g a bachelor is an unmarried man
What is a synthetic proposition?
statement/ assertion which can be verified by subjecting them to empirical testing
e.g dogs bark- can be verified through sound
What is a mathematical propositio?
a statement which is true by mathematical language
What is the verification principle?
Statements are meaningful if they can be verified one of two ways:
1. analytic propositions- true by definition
2. Synthetic propositions- true by confirmation of the senses
What did Ayer think about religious language?
Ayer thought that religious claims are non-cognitive and impossible to verify, so are meaningless
How does the VP support the idea that RL is meaningless?
- Any discussion relating to God and belief isn’t based on common ground
- RL is not univocal so the meaning of an assertion may be unclear (equivocal)
- RL is equivocal language as it is talking about the realm of infinite existence- the result is different interpretations/ understandings of words
Is RL verifiable?
- often RL can’t be understood universally
- you can’t use the VP to prove the statement’s truth
- what does it mean to verify a statement?
Strengths of the verification principle
- Knowledge is accessible to everyone
- Objective/ simple process for verifying statements
- based on physical evidence
Weaknesses of the verification principle
- depends upon scientific understanding
- Can’t look at truths from religion, poetry, history, ethics, and science in the same way: Ayer dismisses many important subjects
- Even if we don’t think a statement can be verified it doesn’t mean that it doesn’t have SOME meaning
- opinions and emotions are unverifiable: ‘I love you’ is unverifiable and according to Ayer meaningless as it is impossible to prove
- ethical and moral statements are unverifiable- ‘do not kill’ no longer has verifiable meaning
- laws of science are unverifiable- ‘gravity always makes things fall’- untestable as can’t infinitely experiement
- the verification principle is unverifiable as it cannot be proven
Who was Anthony Flew?
English philosopher, athiest his whole life until 2004 when he became a deist
What is Flew’s falsification principle?
- Flew was concerned with what makes something false not true
- language only meaningful if we can think of evidence to count against it
- problem with ‘God talk’ is that is often implies it could never be falsified
how does the FP support the idea that religious language is meaningless?
- statement is verifiable, if it is known what evidence could count against it or prove it false
- RL is meaningless as nothing counts against religious statements
- Religious claims can neither be proved true or proved false, as believers don‘t accept any evidence to count against their belief
Strengths of the FP
- meaningful language is that which based on fact
- worthy method- used on science in peer review
- empirical evidence, accessible to all
Weaknesses of the falsification principle
- Not all meaningful statements are Falsifiable some meaningful statements are not falsifiable
- Claims inductive statements as meaningless- as conclusions are probable rather than certain
- Doesn’t Account for Theoretical entities- struggles with theoretical entities that are not directly observable
- Doesn’t Account for Metaphysical claims- struggles with metaphysical claims that are not empirically testable
What are some critics of the FP and the VP and what do they say?
R.M Hare: RL is non-cognitive, can’t make factual statements but is still meaningful
Basil Mitchell: flew is wrong to say that believers don’t lt anything count against their faith, they have a prior commitment to trust God
Richard Swinburne: there are statements that can’t be falsified, yet we understad the meaning behind the satement, e.g toy in the cupboard
R.B Baithwaite: error to treat RL as cognitive when it’s non-cognitive
What is a ‘blik’ and who came up with them?
- a worldview that is meaningful and significant to you
- Hare
How do bliks allow individuals to talk about religion meaningfully?
‘Has meaning not because it imparts knowledge but because it influences the way in which people look at the world’
What parable did Flew write?
set text 1
Parable of the gardener
Give a summary of Flew’s parable
Parable of the Gardener:
- 2 explorers, a believer and a sceptic, come across a garden which has been pruned but still has weeds
- the believer believes there is an gardener who tends to the garden in even though there is no evidence of such, he develops his theory that the gardener is secretive, invisible and scentless to account for the lack of evidence of this gardener, and also deny the weeds
- The sceptic becomes enraged because he claims that the believer is not allowing his original assertion to be falsified and instead edits the claim to add credibility, and believes the believer’s claim has now become meaningless
- god= the gardener
- believer= religious person
- sceptic= athiest/ scientist
- weeds= evil and suffering
What does Flew’s parable ask theists?
- To accept that there is evidence which can point towards disproving God (RL would bemeaninful if it was falsified)
- Accept there is no evidence that can disprove their belief- they will always believe in God no matter the case put before them. Those who believe in God lack the empirical proof of God’s existence but continually believe in his existence
- He challenges theists to verify their assertions- and claims they ignore the laws of falsibility
- Challenges theists to come up with scenarios in which God cannot exist- attemtps to disprove his contingency and certainty
What parable did R.M Hare write?
Parable of the lunatic/ univeristy don
Give a summary of Hare’s parable
A lunatic at university is convinced that all dons want to murder him. Even though there is no evidence to suggest this is true the lunatic believes it completely. Hare compares this to religious believers and says that even though it can’t be proven their ‘bliks’ are still meaningful to them. Therefore RL can be meaningful
