Faith and Reason is the Wnal volume of a trilogy on the philosophy of
theism, the claim that there is a God. The Wrst volume, The Coherence of
Theism, was concerned with what it means to say that there is a God,
and whether the claim that there is a God is internally coherent. It
argued that the claim is not demonstrably incoherent, that it is proper to
look for evidence of its truth, and that evidence that it is true would be
evidence that it is coherent. The second volume, The Existence of God,
was concerned with evidence that the claim is true. It was concerned to
assess the force of arguments from phenomena for and against the
existence of God. It argued that, although it cannot be proved conclusively
that there is a God, on balance the various arguments taken
together show that it is more probable than not there is a God. Faith
and Reason is concerned with the question of what is the relevance of
such judgements of probability (either the particular judgement which
I reached, or a diVerent one—e.g. that it is very improbable that there is
a God) to religious faith.
