6a. Determine the argument form of the above argument.
Notation: W(x): x is willing to prevent evil
A(x): x is able to prevent evil
P(x): x prevents evil
I(x): x is impotent
M(x): x is malevolent
E(x): x exists.
S stands for Superman.
Let’s write the givens:
1: (A(S) ∧ W(S)) → P(S)
2. ¬A(S) → I(S)
3. ¬W(S) → M(S)
4. ¬P(S)
5. E(S) → (¬M(S) ∧ ¬I(S))
6. ¬A(S) ∨ ¬W(S)
7. M(S) ∨ I(S)
8. ¬(¬M(S) ∧ ¬I(S))
9. ¬E(S)
I got this so far
a=superman is able to prevent evil
b= superman is impotent
c=superman is willing to prevent evil
d=superman is malevolent
e= superman exsists
f= superman prevents evil
argument form=
(a∧c)→f
¬a→b
¬c→d
¬f
e→¬b∧¬d
