Modal Ontological Argument

 ...modal ontological argument...John konnor...


1) it is not the case that possibly God exists and it is not necessarily the case God exists


2) God possibly exists


C) necessarily God exists


Let:


G!= God exists


Proof:


1)~(◇G!∧~□G!).          P.

2)◇G!                             P.

3)~◇G!∨□G!                 (1 DeM,DN)

4)◇G!⊃□G!                    (2 M. Impl.)

5)□G!                             (2,5 MMP)

A Meinongian Ontological Argument

 ...a meinongian ontological argument...john konnor... 1. for all x if x has conceivable existence and x has exclusive existence in the understanding then x has    conceivable existence in reality 2. for all x if x has exclusive existence in the understanding then x has conceivable existence 3. for all x if x has conceivable existence in reality then x admits of ontological perfectibility 4. for all x either x has exclusive existence in the understanding or x has actual existence c. God exists let: əUx=x has exclusive existence in the understanding @E!x=x has actual existence ©E!x=x has conceivable existence ©Rx=x has conceivable existence in reality Ix=x is ontologically imperfectible the definite description God g=(℩x)(Ix) proof: 1. (∀x) (©E!x ∧ əUx)⊃©Rx.                premise 2. (∀x) əUx⊃©E!x.                               premise 3. (∀x ) ©Rx.⊃~Ix....
