The Ontological Argument
- Anselm
- reductio ad absurdum
- "God cannot be thought NOT
to exist." - it would be absurd.
- Painter analogy
- For God to be the
greatest thought, He
must exist.
- God exists at least in the mind (de dicto)
whether a person believes or not)
- If God only exists in the mind then he is NOT the greatest
possible being conceived of
- God must exist in reality as well as in the mind in order to be logically
consistent with our definition of God as the greatest possible being.
- His reply to Gaunilo was that he
was not arguing about temporal,
contingent things (like an Island)
- Islands have no 'intrinsic maximum'.
God is not in the same category, he is
neither contingent or temporal
- As such God's existence is necessary
- Descartes
- Defined God as a 'supremely perfect being'
- Because he is perfect, he possesses all perfections
- The perfect state includes existence.
Existence is a predicate of a perfect being.
- Therefore God exists
- Only God has
absolute perfection-
there can't be 2
absolutes
- There are some things that
an object has to have for it
to be an object
- e.g. a bachelor is unmarried
- He argued that God must
exist in the same way a
triangle must have 3 sides
(a predicate)
- Only an absolutely
perfect being can have
necessary existence
- His argument can't apply to objects affected by
space and time (such as Gaunilo's Island)
- It can only be applied to something which is perfect
- Kant
- Analytic Statements
- are true or false in terms of
the words used
- e.g. bicycles have 2 wheels
- Synthetic Statements
- are true or false because
of evidence
- e.g. Sam's bike is red
- Existence is not a
predicate.
- describing someone as 'tall'
adds to our understanding
of the person
- describing someone as 'existing' does not
- adding reality to a
concept does not make
it any better
- e.g. imagining real
money doesn't make
your life better
- If you accept that there is a God,
it is logical to accept also that His
existence is necessary
- BUT you do NOT have to
accept that there is a God
- Others
- Norman Malcolm
- God's existence is either
impossible, or necessary
- since necessary existence
can't be affected by anything
beyond itself, God can't be
'made' to come into existence
- If God does NOT
exist; He can't be
brought into
existence,
therefore his
existence is
Impossible
- If God DOES exist; He can't have
been brought into existence, nor
can he cease to exist
- Garth Moore
- compares the
existence of God
with the existence of
the equator
- There isn't a line drawn round the world
but everyone knows the equator exists -
God's reality is the same for believers, they
don't need to see him to believe he is real
- Platinga
- A maximally great being must
exist in every possible world,
so, God must exist here.
- There are many possible worlds, in
which there exists a being with
maximal greatness
- Russell
- existence can not
be a predicate, if it
was then it would
prove Santa
Clause is real
- Argued Anselm's
use of notion of
necessary
existence
represented a
syllogism
- syllogism is the
interference of one
proposition from 2
premises: e.g. Men
exists- Santa Clause
is a man- therefore
Santa must exist
- Existence is not a
property of things
- It is rather, a numeral concept
- Hume
- a decription of a thing can't contain every possible
detail, but we must go beyond the description itself to
determine whether or not that thing exists
- A thing can't be 'defined into existence'
- No matter how perfect it is.
- All the ontological argument
does is place God's existence
in philosophically rational term
IF He did exist
- Gaunilo
- If I imagine the most
perfect island - does it
make it exist, just
because It is perfect?
