attempts to infer the existence of God from the existence of the universe
argument asserts that the existence of the universe requires an explanation and the claim is that it cannot just account for its own existence
assumes that the universe has not always been in existence and for it to come into being, an external agent was necessary

Inductive -- the conclusion does not necessarily follow the premises, could be more than one logical condition
Premise 1 - All events require a cause
Premise 2 - The universe is an event
Conclusion - God is the cause of the universe
It is only through our regular experience that we assert that most events have a cause
A posteriori
argument is formulated from our experience of the fact that the universe exists and that things are caused to happen by other things
Cause + Effect
argument centres on the principle that if something does not have its own reason for existing then it must have been caused by something else
'Nothing comes out of nothing' - King Lear
Aquinas & First Way from Motion - Summa Theologica
argued that 'whatever is moved is moved by another'
he referred to motion as 'the reduction of something from potentiality to actuality'
First way from motion
eg. fire is hot, fire on wood is actually hot
nothing can be both potential and actual at the same time
Argued that the wood was in a process of change or motion and these changes are the result of prior changes
Aquinas & Second way from cause
follows same line of reasoning as the first way
he argues that the world is a series of events that are caused by other events
its a logical impossibility that an event can cause itself because then it would have to have preceded itself
there must be a first cause upon which all other causes depend
first cause is uncaused
rejected idea of infinite regression of causes
Kalam argument
Islamic version of the cosmological argument
recently this version has been revived by William Craig
this version asserts that everything that comes into existence must have a cause for its existence
therefore universe must also have a cause
no scientific explanation can provide sufficient reason for the origin of the universe --- also rejected infinite regress
Richard Swinburne
distinguishes between inanimate causation and intentional causation
inanimate - when something has the power to act under certain conditions does so
intentional - provides the reason motivated by belief + purpose
Contingency
the universe and all things within it are contingent
while they exist, their non existence is always possible
Aquinas & Third Way from Necessity + Contingency
All things are contingent
'Therefore if everything can not be then at one time there was nothing in existence'
He asserted that there must be a necessary being who does not depend on anything else for its existence - This is God
Infinite Regress
Craig + Aquinas insist that there cannot be an infinite regress of causes
If an infinite regress is accepted then we would never have complete explanations
because the cosmological argument identifies the dependency between cause, movement and events
Example of Infinite regress
imagine a train with an infinite number of carriages where each carriage is pulling the other
without an engine pulling the first carriage it would not be possible
therefore God is like the engine which has the power to be the cause without depending on anything else
Craigs version of the Kalam Argument
actual infinite - refers to a collection of things with an infinite number of members
many philosophers believe that an actual infinite is illogical because no matter what, an actual infinite number can never change
a potential infinite exists if it possible to add to the series
eg. the future could be a possible potential infinite as more events are being added to history
God is a necessary being
cosmological argument accepts a first cause but rejects an infinite series of causes
proposes that God is this necessary being who does not rely upon anything for his existence
Principle of Sufficient Being
Leibniz's argument is that even if the universe had always been in existence
we would need to establish why there is something rather than nothing
Leibniz argued that there is nothing in the universe to show why it exists - it is not self explanatory - so reason for its existence must lie outside of it
Weakness - Inductive Reasoning
With this proof it does not necessarily follow that God must be the cause of the universe
Tyler and Reid argue that it is significant that Aquinas concludes that God is the first mover, cause and necessary being
Strength - Principle of Ockham's Razor
states that the most effective form of philosophical inquiry is the simplest
some may argue that there is no logical reason to assert that God is the cause of the universe but if he appears to be the best explanation then why criticise it
Tyler & Reid state:
'where God suffices as the simplest explanation, why postulate further explanations'
Strength A Posteriori
we have evidence gained from our own experience to support the claim that things are generally caused by other things
the universe must have had a cause for it existence
Weakness A Posteriori
we all interpret our own experiences differently and sometimes our senses can mislead us
Webber on Hume
we would have to experience the cause of other universes to make a justified claim that our own universe had a cause
Hume argues that the argument starts with a concept which is familiar to us, the universe
Strength Causation
we can claim that it is probable that all events have a cause
the universe is an event - so what is its cause?
Limitation Causation
reasoning is based on probability and not fact so it is less effective
Hume argues that it is possible to infer a casual connection between two events only after observing repeated circumstances which are similar
if this is true then it is justifiable to infer a cause of the universe only if other universes had also followed the same event
Limitation Causation
Kant also supports this view
argues that since the concept of causation arises within the space - time world of experience its confined to the observable world
to talk of a cause outside of our experience, a necessary being like God is useless as we have no knowledge of what God created or God himself
Strength - Time & Rejection of Infinite Regress
Aquinas and Craig reject the idea that the universe has always existed and that there is an infinity of causes
infinity is philosophically problematic as it cant be added to
Big Bang theory implies that the universe has a finite history
can God be the cause of the Big Bang?
was the world random rather than a divine intervention
Limitation of Time & Rejection of Infinite Regress
Hawking proposes that the 4 dimensions of space and time are considered as together forming a 'surface'
