not restricted to the 'observables' of sense-experience. Further,
at a time when we are being asked to show what it is that
metaphysics and philosophical theology can have for their
subject-matter when they are not mere verbiage or word spin-
ning, I am bold to think that this limited discussion has a wider
relevance. For I believe that the kind of situation which justifies
belief in freedom and immortality, is the kind of situation to
which we must appeal if we seek an empirical justification for
the language of metaphysics and philosophical theology in
general.

In this book, then, I approach from two directions, the one
a consideration of freedom and the other a consideration of
immortality, the kind of situation without reference to which
the language of metaphysical theology will be logically com-
promised and vacuous. So behind all my discussion is the hope
that while it centres on these two particular topics of freedom
and immortality it will enable the reader to see the sort of
defence which could be given to many traditional concepts,
whether in metaphysics or philosophical theology, by someone
who nevertheless wishes to give full credit to the approach and
techniques of contemporary empiricism.
