Review of David Braine, The Reality of Time and the Existence of
God: The Project of Proving God’s Existence
W. Norris Clarke, S.J.
This
book is a considerable surprise. Coming from a background of analytic
philosophy of language—the author is Gifford Fellow and Lecturer in
Philosophy at the University of Aberdeen and former student of Gilbert
Ryle at Oxford—it ventures out boldly to lay down a robust realist
metaphysics of real substances as active agents exercising active causal
power in time, and then draws from this a carefully worked out argument
to the existence of God as the necessary transtemporal cause of the
whole temporal order of agents. Although grateful for his analytic
training and drawing upon it heavily, the author seems to have reached
his conclusions by his own personal reflections, aided by a profound and
remarkably accurate understanding of the basic positions of Thomas
Aquinas in metaphysics and natural theology. Although he works out his
own technical terminology quite different at first appearance from that
of St. Thomas, the dependence and affinity of thought emerges more and
more clearly as he goes on. This may be the best way, in fact, to make
Aquinas an effective presence in contemporary thought.
But the
book is definitely not for amateurs. It works its way to its
conclusions by an austere and intricately interlocking pattern of
argumentation that requires the closest attention even from a
professional philosopher. One of the difficulties is that the main line
of argumentation to the existence of God is frequently put on hold while
the author works out the basic metaphysical and methodological
foundations on which his argument depends at this point. One can see
why he feels this is necessary in a contemporary context, especially his
own, but it does not make for easy reading. The result is highly
rewarding, however, for those who can stay the course.
The
author’s first move is to justify reflectively the basic common sense
vision of the world as composed of real substances as active agents
exercising active causal power on other substances in a real temporal
order. He does this briefly but well, showing the inadequacy of the
anemic causal theory of the empiricist, David Hume, in which active
causal power is reduced to mere regular sequences of events in time,
such that given the experience of regular sequence we can predict the
consequent from the antecedent according to some law (statistical or
otherwise), but without any ontological link of effective action and
dependence between the two. This theory of the causal relationship,
which would, of course, render it impossible to argue from an
experienced effect to a non-experienced cause (such as God), is still
widely popular among philosophers, at least in its central refusal to
move from something in experience to a cause outside of experience.
He then
goes on to assert the reality of time, in the sense that, although the
past and the present are given, the future as related to a particular
present “now” is radically contingent, that is, it does not yet exist,
is not given; and furthermore, there is nothing in the past of a
temporal being (one whose existence and activity are continuously spread
out across time) that can guarantee or assure its continuance into the
not yet given future. From this he builds his central argument to the
existence of God as a time-transcending cause which does not have or
receive existence but is identical with existence itself. The argument
goes as follows: It is characteristic of any temporal being, whose very
being and activity are imbedded in continuous temporal unfolding, that
it contains nothing within its past or present that can absolutely
guarantee its continuance into the not yet existent future. This
radical impotence to ensure, to be master of, its own future existence
is rooted ultimately in the “compositeness” of every temporal being,
i.e., the non-identity between its nature and its actual continuing
existence, the “that which” and its “is.” Every such being demands a
non-temporal, time-transcending cause that eternally possesses existence
as part of its very nature, is “in charge of existence,” so to speak.
Such a cause does not compete with temporal causes, but is the
necessary precondition for their continued existence as active natures,
exercising their active causality across time into the future.
He then
goes on to show such a cause must be infinite in perfection, one, and
also personal, since personhood is a term inclusive of all perfections,
hence not limited, and necessary for a spiritual-natured cause to
exercise “intentional causality.” He concludes with a cogent argument
that any sound theology must have a metaphysical foundation to give a
critical control over the analogical application and interpretation of
attributes predicated of God.
It is
amazing how close the author is in spirit and doctrinal content to St.
Thomas in all this, though not in terminology. But what of the overall
cogency of the book’s arguments? I think most of his supporting
arguments on points of metaphysics and epistemo-logy, his derivation of
the divine attributes, his insistence on the need of metaphysics for
sound theology, etc. are well taken indeed and show an extraordinary
gift for clear metaphysical thinking in a fresh way that I find most
invigorating. As regards his central argument, though, from the
impotence of any temporal being to ensure its own continuance in
existence and hence its need of a supra-temporal cause, this is a new
form, adapted to temporal existence, of the ancient contingency
argument, taken over by St. Thomas from Avicenna (Summa contra Gentes,
I, Ch. 15, #5), namely, that anything which comes into or passes out of
existence is radically contingent, i.e., it can be or not be, and
thus demands a cause to determine it to be rather than not be. It seems
to me to have great promise and contain a deep truth. But in view of its
central importance the author moves far too quickly through it, seeming
at times to take it as a matter of almost obvious intuition. It needs
more careful unpacking, especially as to the exact relationship between
the compositeness of a temporal being and its impotence to ensure its
continued existence through time.
As a
result of the constant interruption of the main argument to establish
its metaphysical and epistemological foundations in elaborate detail,
often in different parts of the book, the reader seeks in vain for a
single, continuous, uninterrupted development of the argument in full
detail, with the exact weight and reasons for each step presented as it
arises. This is especially needed for the two key steps, 1) that no
temporal being can ensure its own future existence and activity and 2)
that in every temporal being there must be a non-identity between its
nature and its continuing existence (and why this compositeness requires
a cause). What needs more explicit clarification and unpacking is
precisely the root of the contingency of a being whose existence is
unfolded over time. Is it simply the unfolding over time by itself that
indicates the being is not master, or self-sufficient source, of its own
existence? But suppose this development is merely in the accidental
order, with the substance perduring essentially unchanged? Would this
still entail a cause for the existence of the substance itself? Or is
the real core of the argument the exigency that any such unfolding of a
being through time must be dependent for its development on the
cooperation of other beings in the universe over whose being it does not
have control? This point is mentioned once, but it is not clear how
much weight it is expected to carry. It seems to me it carries a great
deal, and may perhaps be the decisive point. But this would make the
argument in substance be one from the dependence of temporal
beings on a wider order of activity in the universe in which they
are inserted, an argument from order in a dynamically developing
temporal system. The point of the argument, if this is it, should be
made clearer.
It is
noteworthy that the author systematically prefers Aristotelian ways of
framing St. Thomas’ arguments, wherever possible, revealing a certain
allergy, or at least undue caution, it seems to be, toward the
Neoplatonically-inspired participation aspect of Aquinas’
metaphysics—now well enough established historically, it would seem to
me—an attitude easily understandable in those coming to St. Thomas from
an analytical background. Thus he gives less metaphysical density to
terms like “finite” and “infinite” than I think Aquinas does, and
maintains that he sees no sound argument to the uniqueness of the First
Cause from its infinity, whereas in fact this path is central to St.
Thomas’ procedure.
He also
seems to be too hasty and unsympathetic in brushing aside the
Transcendental Thomist approach, which he accuses of overstressing a
priori, abstract, universal principles of intelligibility and
sufficient reason—which he unfairly criticizes as “univocal”—rather than
deriving causal intelligibility more existentially from varied examples,
or classes of examples, in experience, which are then only later unified
into general analogous principles. I think he describes St. Thomas’ own
procedure accurately and with insight, but takes for granted the deep
existential drive for intelligibility which underlies for Aquinas the
whole search of the mind for causal explanation and which Transcendental
Thomism is trying to thematize more explicitly and rigorously.
But the
above are secondary controversial points in a book exhibiting both
admirable metaphysical depth and insight and skilled adaptation of St.
Thomas to contemporary modes of thought and language. This fresh new
voice from an author who has promised us also two other major syntheses
of epistemology and philosophy of man is most welcome in a field where
all too few dare to tread these days.
