Mersenne Trademark Argument
...mersennes trademark argument modalized...based on maydoles modal model...john konnor...
1. for all x and all y if x is the cause of y's understanding of x then there exists some x which is ontologically supreme
2. for all x and all y either x is the cause of y's understanding of x or there exists a y that is ontologically perfect
c. God exists ie something ontologically supreme
let:
CxUyx= x is the cause of y's understanding of x
Sx= ~◇(∃y)(Gyx)∧ ~◇(∃y)(~x=y ∧ ~Gxy)
Py= Iy ∧ ◇(∃y))(Ix ∧ Gyx) ∧ ◇(∃y)(Ix ∧ ~x=y ∧~Gxy)
Ix= x is an intellect
g= (℩x)~◇(∃y)Gyx
proof:
1. (∀x)(∀y)CxUyx ⊃ (∃x)Sx premise
2. (∀x)(∀y)CxUyx ∨ (∃y)Py premise
3. Iy ∧ ◇(∃y))(Ix ∧ Gyx) ∧ ◇(∃y)(Ix ∧ ~x=y ∧~Gxy) Def. of P , AIP
4. Iy ∧ ◇(∃y))(Ix ∧ Gyx) 3 simp.
5. ◇(∃y))(Ix ∧ Gyx) 4 simp.
6. ◇(∃y)Gyx 5 simp.
