I, at any
rate, am convinced that He [God] does
not throw dice. – Albert Einstein
I find the
human race’s reluctance to accept concepts such as randomness and chaos quite
fascinating. I suppose, if one believes in a supreme deity, there can, by
definition, be no such thing as randomness and chaos. Everything is planned, if
not precisely predetermined. This is also true if, as an atheist, one believes
in absolute determinism: what happens at this instant is simply the inevitable
outcome of prior events. I suppose the idea of cause and effect is so deeply
ingrained in us that we find the concept of an uncaused cause difficult to
conceive (although that is precisely what theists do all the time!). Kant
considered causality to be one of the a
priori categories. It is one of the givens of reason, prior to any actual
experience of causality. I guess you could say it is hardwired into the process
of thinking and perceiving. As human beings, we cannot but think in terms of causality. Biologically speaking, this
hard-wiring in the brain has evolved as a useful, indeed, necessary way to deal
with the world around us. By and large we can depend on a cause to produce a
particular effect. If it doesn’t, this is because there are other causes at
work which we did not detect, or did not take into account.
On the one hand, we can see this as one of the grounds for skepticism
concerning supernatural phenomena, particularly such things as miracles. We
doubt claims that a miracle has occurred – a miracle denoting some break in the
chain of cause and effect – claiming, instead, that we have simply not yet
detected the actual cause(s). On the other hand, this can also be grounds for accepting the possibility of
supernatural interventions. It could be argued that our reluctance to accept
non-causality is simply due to the fact that we are unable to break out of this
a priori category. For me, this
latter argument does not carry much weight. In fact, supernatural thinking
itself does not break out of this way of thinking. It simply posits an
invisible, unknowable, unmeasurable cause.
Only God himself is truly uncaused.
Quantum theory (and this is what Einstein is referring to in the opening
quote) at the very least rewrites our concept of causality. Concepts such as
“backward causality” begin to emerge: an effect “causes” the cause, rather than
the other way around. Or maybe they cause each other. The concept of
“self-causality” is perhaps not so very farfetched. Yes, it is all very weird,
and I am probably misinterpreting it anyway. In reality, it is probably much
weirder. Does this leave a new “gap” into which God can squeeze? Possibly. But
it may also make the concept of God redundant again. Perhaps “self-causality”
and even “un-caused-ness” are not, after all, exclusive properties of the
divine; they may be basic properties of humble matter.
If it is possible to believe that any one
“being”, such as God, can be uncaused or self-caused, why is it such a stretch
to believe that an entire universe can be uncaused or self-caused? In any case, if the concept of causality is
just a constraint placed upon our way of thinking, a fundamental a priori from which we cannot possibly
free ourselves, this whole discussion is probably a complete waste of time (“time”
being another a priori category).
