The Cosmological Argument attempts to prove that God exists by showing
that there cannot be an infinite number of regressions of causes to
things that exist. It states that there must be a final uncaused-cause
of all things. This uncaused-cause is asserted to be God.
Arguments like this are thought up to recognize why we and the
The Cosmological Argument takes several forms but is basically
It is possible for those things not to exist
Whatever has the possibility of non-existence, yet exists, has been
caused to exist.
Something cannot bring itself into existence because it would have had
to exist to do that.
There cannot be an infinite number of causes to bring something into
existence, because an infinite regression of causes has no original
cause, which means there is no cause of existence.
Since the universe exists, it must have a cause, therefore there must
be an uncaused cause of all things.
This uncaused cause must be God.
Thomas Aquinas (1224-1274) had a version of the Cosmological Argument
called the Argument from Motion. He stated that things in motion could
not have brought themselves into motion but must be caused to move.
There cannot be an infinite regression of movers. Therefore, there
must be an Unmoved Mover. This Unmoved Mover is God.
Strengths of the argument
The strengths of the Cosmological Argument consist of the simplicity
and easily understandable concept that there cannot be an infinite
number of causes to an event. Some arguments for God's existence
require more thought and education in terms and concepts, but this
argument is basic and simple. Also, it is perfectly logical to claim
that objects do not bring themselves into existence and must,
therefore, have causes.
Weaknesses of the argument
One of the weaknesses of the argument is that if all things need a
cause to exist, then God Himself must also, by definition, need a
cause to exist. But this only pushes causation back and implies that
there must be an infinite number of causes, which cannot be. This is
Also, by definition, God is uncaused.
There are two forms of the cosmological argument.
One is the Kalam argument:
Like all cosmological arguments, the kalam cosmological argument is an
argument from the existence of the world or universe to the existence
of God. The existence of the universe, such arguments claim, stands in
need of explanation. The only adequate explanation, the arguments
suggest, is that God created it.
What distinguishes the kalam cosmological argument from other forms of
cosmological argument is that it rests on the idea that the universe
has a beginning in time. Modal forms of the cosmological argument are
consistent with the universe...
