Antony Flew developed falsificationism as an alternative to logical positivism's verification principle. Instead of asking "What would verify this statement?" he asked "What would falsify it? What would prove it false?". If a statement has no conceivable falsifier (nothing could prove it false), then it makes no claim about reality and is meaningless. Applied to religion: "God loves us" is unfalsifiable because believers adjust their beliefs to accommodate any evidence (suffering, evil, tragedy). Flew illustrates this with John Wisdom's Parable of the Invisible Gardener: two explorers find a beautiful garden but never see a gardener. As they add qualifications ("The gardener is invisible," "He transcends physical reality"), eventually the original claim "There is a gardener" dies "a death of a thousand qualifications". R.M. Hare responds that religious language isn't cognitive (fact-stating) but expresses non-cognitive "bliks" (unprovable worldviews). Basil Mitchell argues Flew misunderstands believers who have limits to what would falsify their faith.
Antony Garrard Newton Flew (1923-2010) was a British philosopher.
Definition:
Why Falsification Over Verification?
Example:
Falsifiable Statements:
Have conceivable evidence that would prove them false.
Examples:
Unfalsifiable Statements:
Have no conceivable evidence that could prove them false.
Examples:
The Setup:
Round 1 - The Invisible Gardener:
Round 2 - Beyond Physical Reality:
Round 3 - Testing God:
Round 4 - Beyond Understanding:
Flew's Question:
"But what remains of your original assertion [that there is a gardener]?"
Flew's Point:
The Death of a Thousand Qualifications:
Flew's Claim:
"God is loving":
"Prayer is answered":
Flew's Important Qualification:
But:
However:
Richard Mervyn Hare (1919-2002) was a British philosopher who developed the concept of "bliks" as a response to Flew's falsification principle.
Definition:
The Story:
A paranoid student believes that all university dons want to murder him.
Hare asks: "What would convince him this is false?"
Answer: Nothing—every action the dons take, he interprets as part of the murder plot.
The Key Point:
Religious Bliks:
Similarly, religious faith might be a blik. Religious believers have a non-cognitive, unfalsifiable worldview that shapes how they interpret all events.
Examples:
The Point:
Hare's Argument:
Some of the most meaningful things in life are unfalsifiable bliks:
Hare's Conclusion:
Basil Mitchell (1917-2011) was a British philosopher and theologian who offered a middle position between Flew and Hare in the Falsification Symposium.
The Problem:
The Story (simplified):
During a wartime occupation, a believer in a stranger's benevolence meets a stranger who is sometimes kind, sometimes cruel.
Three Types of People:
1. The Thoughtless Believer:
2. The Partisan:
3. The Madman:
Most Religious Believers Are Partisans:
Examples:
The Difference:
Mitchell's Conclusion:
The Argument:
The Insight:
The Achievement:
Mitchell's Objection:
Evidence:
The Point:
1 Corinthians 15:14: "If Christ has not been raised, our preaching is useless and so is your faith."
This suggests Christianity is falsifiable—falsified by showing Jesus didn't rise from the dead.
Implications:
Hare's Objection:
The Problem:
Flew says religious language is "non-cognitive" (not fact-stating) but "intends" to be cognitive.
This is confusing:
The Objection:
The Turnaround:
"To assert that such and such is the case is necessarily equivalent to denying that such and such is not the case... Now suppose we continue to make cautious adjustments to our original assertion, 'There is a gardener.' We shall be constantly on the watch for the telling move, the final argument. But the believer will still not allow what would count as a definitive disproof of his theory. And by degrees the assertion ceases to be an assertion and becomes a mere shadow of itself... The believer causes God to 'die a death of a thousand qualifications.'"
"The student's belief 'All dons want to murder me' is unfalsifiable. No evidence will convince him otherwise. Yet his belief is not meaningless—it profoundly shapes how he lives and interprets reality. Similarly, religious faith might be a 'blik'—an unfalsifiable, non-cognitive worldview that is nonetheless deeply meaningful to believers."
