We know the universe began
to exist. That fact is agreed upon by the majority of theists and atheists
alike. But what else can we know from that fact? By conceding that the universe
has a beginning, does that give us proof of the Christian God? Not really, but
it gets us closer than you may initially realize.
The first thing one can
infer is whatever it is that caused the universe to exist (I will refer to this
as the Cause with a capital C) must itself exist prior to the universe and its
created parts. This means that the since the Cause created all matter, it must
itself not be made of matter. If the Cause is made of matter, then it isn't an
explanation of the universe, it is part of the universe. The cause of the
universe must be immaterial.
Yesterday, I wrote about the fact that since time is also a part of the
created universe, the cause of the universe's existence must be at least
initially timeless. It must exist in a state of timelessness prior to any
creative act. However, this conclusion adds additional facts to the picture. As
I said yesterday, one can define time as a change in states or a succession of
events. If there is a before and after, there must be time involved. Therefore,
at the creation event time begins because there is a change in states. The Cause
was not creating in its timeless state and it now is.
Such a description is
fine when one is thinking about time beginning, but it begs a question: what
makes the Cause start creating at all? If the Cause (whatever it is) is
timeless, then why all of a sudden start creating? Here is where we need to
differentiate how different causes work, and it leads to some interesting
conclusions.
Two Types of Causes
There are two types of causes that we have observed through all of history.
The first are causes that are the result of a certain set of circumstances. The
35th domino in a line of dominoes falling will cause the 36th domino to fall. In
the same way, vinegar will cause a cup of baking soda to react and ultimately
cause carbon dioxide gas to be released. Similarly, heat will cause fuel and
oxygen to ignite into fire. All these causes (the domino, the vinegar, and the
heat) create an effect that follows inevitably from the laws of nature. They are
what I would call mechanical and they are contingent upon the universe being the
way it is. Given the chemical properties of baking soda and vinegar the effect
must occur if the causal conditions are met.
But such causes require other
things to already be in existence. The 35th domino wouldn't have fallen had the
34th domino not fallen. The force of gravity must exist (lining up dominos in
the International Space Station is much harder to do and won't give you the same
effect.) Molecules must be able to share electrons in a certain way before the
vinegar can react with the baking soda. There is therefore no mechanical cause
that can jump start the whole process.
The
other type of cause is a personal cause. Personal causes can happen
spontaneously. If I have a desire to raise my arm, I simply raise it. There
needs to be no preceding event that makes me want to raise my arm. The cause is
created in my mind. While some desires or intentions may stem from external
stimuli (such as wanting to raise my arm because it is tired, it aches, or I
want to answer a question the teacher posed), such a prior cause is not
required. I'm not compelled to answer a question the teacher posed, I may simply
want to contribute to the discussion. I may simply have a desire to answer and I
then intend to answer by causing the effect of putting up my hand.
Desired from Eternity Past
Of the two types of causes we know, which would be better at explaining the
cause of the universe? The first one can't do so because it requires something
to exist already. Some try to argue about the laws of gravity creating the
universe, but such arguments
fail to take into account what's required before any law, including gravity,
can work. These kinds of causes don't answer the question of beginnings, they
simply push it back a step and imagine a universe-making machine. The obvious
question is "what made the machine?"
The second kind of cause makes more
sense. But intentions and desires don't exist on their own; they are the
products of a mind. A mind
is not a physical thing, like a brain. It is
fundamentally different and because thoughts, intentions, and desires are
themselves immaterial, they can be present in an immaterial mind.
So, we
have a Cause that is immaterial, timeless, and shows desire to create. That
means the cause is personal; it has a mind. You may at this point say, "But
wait! How can a timeless mind have a desire? If there is a change in the Cause
where a desire is created, that means such a Cause is not timeless." This is
true. However, it isn't necessary that a desire come into being. Some intentions
or desires can always be there. Think about the desire to survive, for example.
All humans have it, even if they never have to exercise it. The desire for life
exists since birth, but only when we are threatened do we act upon it.
It is
reasonable, then, to have a timeless, immaterial, personal Cause for the
universe that desired to create (and create us) from the eternal past. While
that doesn't specifically argue for the Christian God, it comes pretty close and
excludes a whole lot of other contenders.
