ChatGPT, when fed a copy of the book, said this: “According to this uploaded 2007 book, There Is a God, Antony Flew explicitly states the reasons that led him to cease being a strict atheist and adopt a minimal, deistic belief in a Creator. These reasons are present in the text itself, and they do not include age, emotion, fear of death, Pascalian betting, or reading Aristotle for the first time.
Here is what the file shows.
What Antony Flew says were his reasons for changing his mind
The introduction of the book states that Flew is now giving the first full account of the arguments and evidence that led to the shift:
“Now, for the first time, he gives an account of the arguments and evidence that led him to change his mind.”
A few pages later, Flew himself describes what triggered his shift:
“Ever since the announcement of my ‘conversion’ to deism, I have been asked… to provide an account of the factors that led me to change my mind…. In brief… I now believe there is a God!”
He immediately clarifies that this was not due to age, fear of death, or emotion:
Critics claimed my age had something to do with my conversion… Clearly these people were familiar with neither my writings… nor my current views…. I want to lay to rest all those rumors….
So what were the actual reasons he names?
1. Scientific evidence concerning the laws of nature
The table of contents shows an entire chapter titled “Who Wrote the Laws of Nature?”
This theme appears repeatedly in the introduction. Flew emphasizes:
-
the intelligibility of the universe
-
the mathematical structure of physical law
-
the question of the source of rational order
These factors led him toward belief in a rational Mind behind the cosmos.
2. Fine-tuning and cosmic purpose
One of the chapters is titled “Did the Universe Know We Were Coming?” — an explicit reference to the fine-tuning problem.
Flew repeatedly states that the appearance of a universe fit for life demanded explanation.
3. The origin of life (“How Did Life Go Live?”)
Flew includes a full chapter on the origin of biological complexity.
The content summary indicates that Flew believed new scientific discoveries about DNA and cellular complexity provided positive evidence for intelligence.
4. The impossibility of something coming from nothing
He dedicates another chapter to “Did Something Come from Nothing?”
Flew rejected philosophical and scientific attempts to explain the universe’s existence without a cause.
5. Re-evaluation of Hume and causation
This is the most philosophically important part.
Flew explicitly states that he had to reverse his earlier reading of Hume’s skepticism about causation:
“The three chapters… need to be rewritten in light of my new-found awareness that Hume was utterly wrong… Hume’s analyses… have been far too weak…
Hume denied causation…
This has misled generations…”
This is a major revelation.
He is saying:
My old Humean metaphysics (foundation of modern atheism) was mistaken.
Once he abandoned that, the inference to a Creator became (for him) philosophically permissible.
6. “Following the argument wherever it leads”
Flew repeats his lifelong principle:
“As a professional philosopher… the principle of following the argument wherever it may lead me.”
Thus:
He presents his change as an intellectual consequence of the above evidence, not an emotional conversion.
Summary: What Flew actually acknowledged (according to the book itself)
From the document, Flew’s reasons fall into three categories:
A. Empirical Evidence
-
Rational order of the universe
-
Fine-tuning of physical constants
-
DNA and complexity of life
-
Scientific arguments about origins
B. Philosophical Revisions
-
Rejection of Hume’s denial of causation
-
Acceptance of real causal powers and necessary beings
-
Abandoning materialistic metaphysics
-
Openness to classical theistic arguments
C. Personal Intellectual Integrity
What Christians then claimed
Because Flew publicly adopted:
-
belief in a Creator
-
belief in an eternal, omnipotent, non-material Mind
-
rejection of strict atheism
-
rejection of materialistic explanations of life and the universe
Christians described him as “no longer an atheist.”
But he is clear that he became a deist, not a Christian, and explicitly did not accept an afterlife:
“I have not changed my mind. I do not think of myself ‘surviving’ death.”
