Does God exist

args against God

args for God

divine attributes

paradox of divine moral perfection

Impeccability

possible worlds

paradox of the stone - pseudo-Dionysius the Areopagite

omniscient --> all knowing

omnibenevolent --> all loving

omnipotent --> all powerful

Orthodox 'Anselmian' understanding of God - has these attributes cause he's perfect - has them essentially

aseity --> depends on nothing / has no cause

immutable --> unchanging

incorporeality

simplicity --> no parts/constituents

omnipresent

cosmological arg

teleological arg

ontological arg

others:

arg from conciousness

arg from evolution

arg from hell

arg from non-beleif

arg from poor design

omnipotence paradoxes

prob of evil

the arg:

the reductio

2) but what counts as anything - even the logically impossible?

3) can God deny/restrict himself

1) God is omnipotent

4) can god make a stone he cannot lift?

yes - something he cant do - lift the stone

no, something he cant so - not omnipotent

can - fallible & not divine

cant - something he cant do & not omnipotent

responces

P1) God exists

5) exists someone who can bring about a stone, s, that no-one can lift (from 4)

6) exists someone who can lift s (from 4)

4) there exists something that can bring about anything (from 1,2,3)

7) s both can & cannot be lifted (from 5,6)

P3) omnipotent being can bring about anything

P8) impossible something can & cannot be lifted

P2) if God exists would be omnipotent

9) contradiction (from 7,8)

P1) God exists

paradox is a reductio - might take as 1 for atheism

P2) if God exists would be omnipotent

some wonder if God needs the attributes commonly ascribed

cant go too far with this --> otherwise you aren't describing God

P3) omnipotent being can bring about anything --> the 'standard solution

many ways to define omnipotence:

  • x is omnipotent off x can do anything (poss or imposs)
  • x is omnipotent iff x can do anything (only if logically possible)
  • x is omnipotent iff x is 'maximally great' (more power than any other being)

if 2 or 3 true - God doesnt need to be able to make the stone --> no slight against power just not logcally possible

'worlds' = universe/'everything that actually exists'

everyway world could be - God can make universe that way

actual world = our universe

BUT can only make logically possible worlds

use to talk about things like paradoxes easier

translate modal talk into poss worlds talk

model terms --> poss world terms

possibly P --> At some possible world P

its impossible that P --> At no poss world P

necessarily P --> at every poss world P

dont mix terms - e.g. dont use poss world talk with 'could' or 'possible'

poss worlds are heuristic - few beleive they really exist

Gid is essential omnibenvolent --> hes impeccable

"it is impossible for God to lie" - Hebrews 6:18

Conflict w/ impeccability

if all powerful can do anything --> e.g. torture for no reason

if impeccable/omnibenevolent impossible to do evil things --> e.g. impossible for him to torture for no good reason

Conc: God cant be both essentially all-powerful & essentially all-good

therefore there cant be perfect being - God

poss worlds talk:

X is essentially F = df at every possible world at which X exists, X is F

premises & paradox lay out:

P4) if being x has ability to do x, then is poss they do x (poss world at which it does x)

5) for any logical poss activity there poss world where God does it (from 2,4)

P3) at every poss world at which God exists he fails to sin (by definition of God)

P6) logically poss for someone to sin

P2) at every poss world at which God exists, hes omnipotent

7) is poss world at which God sins (from 5,6)

P1) god exists

8) is a poss world at which God sins & there isnt a poss world where God sins --> contradiction (from 3,7)

by reductio have to abandon a premise
