What is the Cosmological Argument?
• In brief, the cosmological argument is an argument for the existence of God which
claims that all things in nature depend on something else for their existence
(i.e., are contingent), and that the whole cosmos must therefore itself depend
on a being which exists independently or necessarily.
Context
• Although the cosmological argument is one of the oldest philosophical arguments
for the existence of God, a significant development happened in the thirteenth
century with St Thomas Aquinas.
Aquinas’ Cosmological Arguments
• Aquinas posited three different cosmological arguments, argument from
motion, causation, and contingency.
, Briefly - What does he argue?
• The basic premises for all of his cosmological arguments argue along the lines of:
There are things that are in motion, caused, contingent. These things require
something else to move, cause, create them and so on. The chain of causation
cannot go back forever. Therefore, there must be an unmoved mover, an
uncaused cause or an uncreated being.
What is Aquinas’ Argument from Contingency?
In his Summa Theologica, Aquinas argued that we need a causal explanation for the
existence of contingent beings.
What is a Contingent Thing?
• A contingent thing is something that is dependent on something else for its
existence and could have not existed.
What is a Necessary Thing?
• A necessary thing exists independently of anything else and has always
existed, will always exist and cannot not exist.
His argument can be summarised as the following:
1. A contingent being (a being such that if it exists, it could have not existed or could
cease to exist) exists.
2. This contingent being must have a cause of or explanation for its existence.
3. The cause of or explanation for its existence is something other than the contingent
being itself.
4. What causes or explains the existence of this contingent being must either be solely
other contingent beings or include a non-contingent (necessary) being.
5. Contingent beings alone cannot provide a completely adequate causal account
or explanation for the existence of a contingent being.
6. Therefore, what causes or explains the existence of this contingent being must
include a non-contingent (necessary) being.
