“God exists” is an intuitive, basic
belief of mine. (To be clear, by the term “God” I do not mean a metaphor for
the nature of reality—rather, I am referring to the classical Christian
conception of God drawn from the Old and New Testaments. See the Westminster
Confession of Faith Ch. 2 for a condensed statement on the subject.) Unfortunately,
when confronted with opposition to some of our most basic intuitive beliefs, it
is often difficult to provide evidence or arguments in favor of those
beliefs—because they are the beliefs by which we evaluate evidence and
formulate arguments. If I challenge you to prove the existence of your right
hand, you might wave it in my face or touch me with it. But if I ask you to
prove that space and time exist, you might just scratch your head in confusion.
The existence of space and time is something which we often assume for the
purpose of providing evidence or argumentation regarding other subjects. It can
be difficult to explain and defend one’s intuitions inferentially. How would
you respond to someone who stands before you, using the air she is breathing to
deny the existence of both air and her own voice?
By analogy, arguing for the existence of
the Creator of space and time is no
less difficult than defending one’s belief in space and time itself, since—if
God exists—his existence is even more foundational than the existence of his
creation. So, on the question of the existence of God, either atheists are radically
self-deceived or theists are. Either I believe in an “imaginary friend in the
sky” or atheists, like Mr. Courtney, are assuming the existence of God in order
to argue against the existence of God. One of us is colossally wrong.
There are many ways that people have
responded to skepticism regarding a belief in God. I’ll provide four brief
arguments in this regard. The first two will be arguments for the existence of God;
the second pair will be arguments against atheism. These arguments aren’t
original to me, though I will take responsibility for their particular presentation
in this debate. I am indebted to the writings of Cornelius Van Til, Alvin
Plantinga, Greg Bahnsen, John Frame, Gordon Clark, Steve Hays, John Byl, David
Byron, James Anderson, and Greg Welty (among others). I’m also grateful for Mr.
Courtney’s patience during our exchange and willingness to debate someone with
no experience in formal debate.
Transcendental
argument for God from mathematics.
Hermann
Weyl famously defined mathematics as “the science of the infinite.” Set Theory
combined with Predicate Calculus provides the foundations of mathematics. The
ultimate goal is to describe the structure of the mathematical universe,
emphasizing systems of internal consistency and proof. Certain equations imply other
equations, membership in one set implies membership in others, addition implies
subtraction, etc. In a system with internal relationships, such as the number
4’s relation to 2, all of the relations must be consistent in order for any of
them to be consistent. 2+2=4 because 1+1=2 and 4-2=2, etc. So, in a system of
infinite internal relations, the infinite must be actual rather than potential.
Mathematical
objects also appear to be inherently mental objects. What else could they be?
2+2 doesn’t transform into 4. 2,000,000 doesn’t have any more mass than 2. The
existence of a number is independent of the existence of a particular
instantiation of its properties, i.e. if I erase the symbol “9” from a
chalkboard or smash two apples into sauce I haven’t affected the number 9 at
all. But if numbers are mental objects which are members of an actual infinite
set, this requires the existence of an infinite mind where they inhere—the mind
of an eternal, omniscient God. 2+2=4 only if God exists.
Anderson and
Welty’s argument for God from logic.
“The
laws of logic are necessary truths about truths; they are necessarily true
propositions. Propositions are real entities, but cannot be physical entities;
they are essentially thoughts.
So
the laws of logic are necessarily true thoughts. Since they are true in every
possible world, they must exist in every possible world. But if there are necessarily
existent thoughts, there must be a necessarily existent mind; and if there is a
necessarily existent mind, there must be a necessarily existent person. A
necessarily existent person must be spiritual in nature, because no physical
entity exists necessarily. Thus, if there are laws of logic, there must also be
a necessarily existent, personal, spiritual being. The laws of logic imply the
existence of God.” (James Anderson, Greg Welty. “The Lord of
Non-Contradiction,” Philosophia Christi 13.2)
Argument
against ultimate non-personality.
According to the law of excluded middle,
reality is ultimately either personal or non-personal. (A minimalist definition
of “personal” would be a “rational, self-conscious entity.”) If reality is
ultimately personal, then the existence of human persons is almost self-evidently
explicable: persons come from other persons (via creation or reproduction).
However, if one maintains reality is ultimately non-personal, as atheists do,
then problems arise in explaining how personality emerges from non-personality,
how rationality is produced by non-rationality. Note that there is not even a
standard accepted theory of abiogenesis (despite many experiments conducted by highly
rational persons), which is a much less difficult question than the origin of
personality, given ultimate non-personality.
Argument
against atheism as self-refuting.
Mr. Courtney is about to make his
opening statement. I predict there will be truth claims within that opening
statement. Regardless of one’s theory of truth (correspondence vs. coherence
vs. pragmatic, etc.), that theory will depend upon the existence of a mind, in
which propositions correspond with external reality or cohere with other true
propositions or are most expedient, etc. However, if we combine atheism with
standard scientific theories on the evolution of life, there was a time when no
minds existed—but would it be true to say of that time that no minds existed
then? Answering “no” is plainly self-contradictory. If the answer is “yes,”
then how can something that was not true at that time become true now with
reference to then? Either answer is self-refuting. Only if we grant a divine
mind, where this truth may inhere, can one even predicate that there was a time
when no human minds existed.
I look forward to reading Mr. Courtney’s
opening statement.
