Kalam: God as a boundary condition!
Unfortunately I won’t be
attending the event, so I’ll have to make do by commenting on the article as it
appears on Network Norwich and Norfolk.
“In the beginning was the Word”. One very old argument for the
existence of God states that everything that comes into being has a cause. Our
universe has come into being. Therefore it must have had a cause, and the
obvious candidate for this is God. The Big Bang model of the universe has
provided a new impetus for this argument. However, there are a number of recent
theories that see our universe as having had an earlier existence, prior to the
Big Bang, which could possibly be infinite.
My Comment: The concept of “cause”
envisaged here is one that is very much bound up with time: The reasoning goes something like this: “It wasn't here before today but it
is here now, therefore it must have some prior cause”. I have trouble with this
concept of “cause” given that physics seems to be a way of describing the patterns
of physical ontology using mathematical functions. If an ontology has a given
pattern, is the cause of this pattern to be found in an antecedent conditions or
in the mathematical constraint that describes that pattern everywhere and
everywhen? In this sense “causes”, so-called,
are found everywhere and everywhen and not just in past “boundary conditions”. I would therefore question whether it
is meaningful to talk about a concept of “cause and effect” strictly bound to
antecedents. In particular, a very temporal concept of causation is inappropriate
to statistical patterns constrained by
functions that control distributions; it is meaningless to try and explain the
elements of these statistical patterns without reference to the timeless logical objects that constrain it.
In his talk Dr Bussey's talk will consider the plausibility of these
scenarios and their impact, if any, on the argument for God as the first cause,
known as the “Kalam argument”. The Kalam argument relies on the universe not
being infinitely old.
My Comment: Binding the “Kalam argument”
to a universe of finite age bears out what I have already said, namely, that
the concept of causation being offered here is very much bound up with
antecedents. In this argument God takes
his place amongst an identity parade of possible antecedent “causes” some of
which may be designated as “natural” as opposed to “supernatural”. If one opts for
the “supernatural” cause God becomes merely “the first cause” at the beginning
of a chain of otherwise “natural” causation. If you are a deist then you
believe that once the “first cause” has acted he stands aside and lets things
run their “natural” course. In fact Western
Christian theism may actually be not so far removed from deism; the only
difference being that in Western Christian theism the “first cause” is believed
to occasionally “intervene supernaturally” in an otherwise quasi autonomous natural order. Thus, if you take away
these “interventions” you are back to deism! The dualism here is apparent: The
natural and supernatural orders are sharply distinguished as two different
categories of causation.
Quantum
physics enables a causal ‘arrow of time’ to be more clearly identified than in
classical physics, making better sense of the idea of a First Cause.
My Comment: What I think is being
envisaged here is that the random reduction of the state vector in quantum
mechanics entails a physical algorithm that every so often clears
its “memory banks” of information thus making physics irreversible. (Not true
in the parallel histories interpretation of QM). This will give an absolute
direction to time and a stronger reality to the progressive sequential nature of physical processes, thus paving the way to a non-cyclic cosmology with an initial temporal hiatus that lends itself to the "first cause" paradigm.
There are serious problems with physical infinities and this
requires that an argument for an infinitely old universe has to be rigorously
stated. Considerations involving increase in entropy production, stability and
the Borde-Guth-Vilenkin theorem suggest that the universe (or any time-extended
cosmos) is very likely to have had a start in time.
My Comment: The general mathematical
principle being invoked here can be found in algorithmics. The computations
inherent in some functions cannot be meaningfully wound back in time
indefinitely. There comes a point when the computations prior to a certain time
in the past are undefined. So yes, it may well be that the physical
computations that run our cosmos have a definite start time. However, it is one
thing to hypothesize physical functions that can’t be run back in time
indefinitely and quite another to make one’s theology depend on it.
From this it follows that the Kalam argument holds, but the argument
should also be seen in the context of wider theological viewpoint.
My Comment: The Kalam argument follows if
your theology sharply distinguishes between natural and supernatural causes
as events; that is, as objects embedded
in history. In fact the argument here isn’t much more sophisticated than this:
“If you can’t find a “natural” cause that
did it, then God must have done it!” (Notice the past tenses here!). But if
the computations of physical functions do indeed run past the “big bang” you’re
back to square one because the Kalam argument is then negated. “Natural
causes did it, therefore God didn’t do it!” (Incidentally: From my reading
of Genesis 1 it is not 100% clear that we have there an absolute beginning)
***
I have must say that I'm a
little bit disappointed that scientists like Peter Bussey are still toying with
the Kalam argument (if only to consider its merits and demerits) as I had hoped they would have moved on from this dualist dichotomy.
In the Kalam argument God is evoked as a kind of special temporal boundary
condition. If the cosmos does have an absolute beginning it would simply be another facet of The Grand Logical Hiatus in which our
cosmos is immersed. The logical edge of the universe is everywhere and everywhen
and not just in the distant past where the ability of physical algorithms to
meaningfully describe the patterns of the cosmos runs out. Once again God’s eminence
is being stressed at the expense of his immanence. This is the paradigm of Western
dualism for you.
