RL -20th C Perspectives Flashcards
VERIFICATION PRINCIPLE
VIENNA CIRCLE
- Vienna Circle of logical positivist influenced by Wittgenstein and Russell
- Wanted to establish criterion of meaning
- If we can’t rest it and empirically verify it then it is meaningless
- Any statements about God, ethics are meaningless
A J AYER
INTRODUCTION
- Hugely influenced by logical positivist
- Book: language, truth and logic 1936)
A J AYER
VP IN PRINCIPLE AND PRACTICE
- Don’t just have to be able to practically verify something
- You can also verify something in principle (under conditions might be true)
- Scientists can’t always practically verify something
- 1936, mountains on the moon
STRONG VERIFICATION PRINCIPLE
- Vienna circle, required conclusively verified
- Impossible as we can never conclusively make any statements about the world as our senses can be mistaken
WEAK VERIFICATION PRINCIPLE
- Should instead be used ‘if it is possible for experience to render it probable’
- Some basic statements can be conclusively verified e.g. Cat is on my bed
- Ayer thefts religious language as nonsense because it tells you nothing factually significant
- Might be emotionally significant to say there is a God but not actually meaningful
VERIFICATION PRINCIPLE
STRENGTH
-More helpful to scientist than original principle as you only have to show that statement is probable, allows more scientific theories to be meaningful
VERIFICATION PRINCIPLE
PRINCIPLE ITSELF NOT MEANINGFUL
-As it cannot be verified. It is neither a tautology or empirically verifiable, created a criterion of meaning it did not pass itself
(Ayer said used to verify statements not theories)
VERIFICATION PRINCIPLE
MAGEE QUOTE
‘This new scalpel was, in one operation after another, killing the patient’
COUNTER-CRITICISM
PROTOCOL STATEMENTS
- Some tried to defend VP by saying there was a 3rd type of meaningful statements - protocol statements of method
- However, this undermines the original idea what only two types of statements are meaningful
VERIFICATION PRINCIPLE
ASSUMPTION OF SCIENCE
-VP makes assumption that only science can tell is about world, why is empirical verification something that makes it meaningful. Too narrow, can’t we learn things from poetry and art and expression of ideas what have factual significance
VERIFICATION PRINCIPLE
CRITICISM - JOHN HICK
- Religious statements can be verified, especially if we take idea we can use verification in principle
- Road to celestial city, going to verify it at the end of the road
- Same way when we die we will be able to verify our statement whether there is a God or not or an Afterlife
- Using weak VP I can verify my statements in principle, evidence is design
VERIFICATION PRINCIPLE
CRITICISM - VINCENT BRUMMER
- Not appropriate to use scientific views of statements and apply them to religious statements
- Influence of those like Ayer and Flew, Dawkins, people think if something is not scientific (measurable) then it is not worthwhile
- That is not self evident, it is a choice
FALSIFICATION PRINCIPLE
OVERVIEW
- Not development of verification principle. Alternative idea and not about meaning
- Karl popper, this is what science is, we should be open to falsification when we put forward a theory
FALSIFICATION PRINCIPLE
ANTHONY FLEW
- Takes Poppers theory and applies it to religious language
- Not that religious language is meaningless but not as meaningful as scientific statements
- Nit as valuable as not open to falsification
FALSIFICATION PRINCIPLE
JOHN WISDOMS PARABLE OF GARDENER
- People come across well tended land ‘must be a gardener’
- Test and find no evidence of gardener, each time falsify come up with excuse ‘maybe he is invisible’
- When religion is falsified they attempt to qualify their statement
