Antony Flew has spent nearly two-thirds of his life arguing against the
existence of an omnipotent and all-knowing God, but towards the end of
his life, he has accepted the existence of one. He argues that his change is
due to the principle of “follow the argument wherever it leads”. He states
that at first the argument required to oppose the existence of God, but the
argument now leads him to accept the idea that there is a God. This study will
consider whether Flew applies the principle “follow the argument wherever
it leads” when it comes to Islam. While doing this, first, Flew's conception of
God, which he endorsed after accepting the existence of God, will be briefly
described. Then, his thoughts on Christianity after the acceptance of God’s
existence will be addressed. Next, the arguments he developed against Islam
will be evaluated. Finally, it will be discussed whether he adapts the principle
of “follow the argument wherever it leads” when Islam is at stake. As a result,
it has been seen that Flew should at least have shown the tolerance he showed
to Christianity, which he rejected, to Islam in accordance with the principle of
“follow the argument wherever it leads” nevertheless, he did not reconsider
his former harsh and biased claims about Islam.
