3.3.3 - University Debate - falsification, Partisan and bliks

The Falsification Problem

The University Debate starts with a simple pressure on religious language. When someone says "God loves us", do they make a factual claim about reality, or are they doing something else?

A factual claim normally rules out some possible state of affairs. "There is a cat in the room" rules out there being no cat in the room. "This medicine lowers fever" rules out it having no such effect. If a sentence appears to make a factual claim but nothing could ever count against it, Flew asks whether it really asserts anything.

The key terms are:

Falsification is not the same as actual falsity. A claim can be meaningful and falsifiable even if it is true. The point is that a meaningful factual claim must exclude something. If it is compatible with every possible outcome, it may no longer be saying how the world is.

Flew's opening challenge can be reconstructed like this:

Claim at issue: Some religious utterances fail to assert anything factual.

1. P1: A sentence makes a factual assertion only if some possible state of affairs would count against it.
2. P2: Some religious believers allow no possible state of affairs to count against claims such as "God exists" or "God loves us".
3. P3: If no possible state of affairs counts against a sentence, the sentence does not rule anything out.
4. Therefore, C: For those believers, such religious utterances fail to make factual assertions.

Hidden assumption: Factual meaning requires a contrast between what would support the claim and what would count against it.
Inference type: Conceptual and semantic argument.
Main pressure point: Whether unfalsifiable religious language is empty, or meaningful in some other way.

The debate is not mainly about proving that God does not exist. Flew's challenge is sharper: if religious believers protect their claims from every possible counterexample, the claims may stop functioning as genuine assertions at all.

Flew And The Gardener

AQA names Flew's use of Wisdom's Gardener. John Wisdom's earlier garden story explores how a hypothesis about a gardener can begin as an experimental claim and gradually become something less like an ordinary testable hypothesis. Flew adapts that background for a more direct falsification challenge.

Flew's parable is lean. Two explorers find a clearing with flowers and weeds. One says there must be a gardener; the other denies it. They watch, set tests, and look for signs. No gardener appears. The believer keeps qualifying the claim: perhaps the gardener is invisible, intangible, undetectable, without scent, and so on. The sceptic then asks what difference remains between such a gardener and no gardener at all.

The point is not that invisible things are automatically impossible. The point is that each qualification removes one possible way the original claim could have been tested. If all possible tests are removed, the claim may suffer what Flew calls "the death by a thousand qualifications".

Flew applies the pattern to religious language:

The argument can be reconstructed like this:

Claim at issue: Unfalsifiable God-talk is not a genuine factual assertion.

1. P1: A genuine factual assertion must make a difference to what we should expect or count as evidence.
2. P2: In the Gardener parable, the believer's repeated qualifications remove every possible observable difference between a gardener and no gardener.
3. P3: Some religious claims are defended in a similar way, so that no suffering, silence, or failed expectation is allowed to count against them.
4. P4: If a claim makes no possible difference to expectation, evidence, or contrast with its denial, it has lost factual content.
5. Therefore, C: Some religious claims are not false factual assertions but fail to assert anything factual.

Hidden assumption: To assert that God exists or loves us must involve some possible contrast with God not existing or not loving us.
Inference type: Analogical and conceptual reasoning.
Main pressure point: Whether religious claims need to be falsifiable in the same way as ordinary empirical hypotheses.

Flew's challenge is initially plausible because religious claims often sound cognitive. "God loves us" sounds as if it describes how reality is. If that is right, then terrible suffering seems at least relevant evidence against it. A believer who says suffering makes no difference at all seems to be using the sentence in a way that no longer resembles ordinary factual assertion.

But the argument is vulnerable. It assumes that the religious believer must treat God-talk like a hypothesis about a hidden object in the world. Mitchell and Hare both resist that assumption, but in different ways: Mitchell keeps religious language as assertion, while Hare gives it a non-cognitive role.

Mitchell's Partisan Response

Basil Mitchell thinks Flew has made the theologian too evasive. On Mitchell's view, a serious believer does not deny that suffering counts against belief in a loving God. The believer's position is more like trust under pressure.

Mitchell's parable is the Partisan. In wartime, a resistance fighter meets a Stranger who deeply impresses him and says he is on the side of the resistance. Later, the Stranger sometimes appears to help the resistance and sometimes appears to help the enemy. The Partisan continues to trust him, not because nothing counts against the Stranger, but because his original encounter gave him a reason for commitment.

The key distinction is:

This is Mitchell's main reply to Flew. Religious utterances can be assertions even if they are not conclusively falsifiable by a single observation or by any simple test. Many meaningful claims about persons, loyalty, history, and interpretation are not abandoned whenever evidence becomes mixed.

Mitchell's response can be reconstructed like this:

Claim at issue: Religious utterances can remain genuine assertions even when faith prevents decisive falsification.

1. P1: A genuine assertion can face evidence that counts against it without being conclusively falsified by that evidence.
2. P2: The believer's claim that God loves us faces real counterevidence, especially pain and suffering.
3. P3: A serious believer recognises this counterevidence and experiences the conflict it creates.
4. P4: Faith can involve trusting God despite unresolved counterevidence, rather than pretending there is no counterevidence.
5. Therefore, C: Religious claims such as "God loves us" can be meaningful assertions, provided the believer allows evidence to count against them even if not decisively.

Hidden assumption: Trust can rationally shape how evidence is weighed without making the claim empty.
Inference type: Analogical and conceptual reasoning from the Partisan case.
Main pressure point: Whether refusing any decisive falsifier still protects the assertion too much.

Mitchell's reply is strongest when the believer does three things:

1. Gives some initial reason for trust.
2. Admits that suffering and silence count against belief.
3. Feels the full force of the conflict instead of using religious language as a comforting formula.

The reply is weaker if the believer treats every possible event as irrelevant. Then the view falls back into Flew's target: language that seems to assert something, but makes no difference to what evidence can count for or against it.

Hare's Bliks Response

R M Hare responds more radically. He accepts that, on Flew's ground, religious utterances may not work as ordinary factual assertions. But Hare denies that this makes them pointless or meaningless.

Hare introduces the idea of a blik.
