Can a Catholic Critique this Moral Philosophy?

[Freddy]

Freddy:

4 is an assumption. And 7 assumes the conclusion.

4 is the principle of causality, if it requires rejection of causality and the rejection of the principle of sufficient reason to be an atheist, then that should say something

7 is deduced logically.

Causality is always assumed. If you preface your point with: ‘On the assumption that…no potential etc’ then I will agree with it.

And 7 is a supposition. You actually admit that within the item itself: ‘…presupposes the concurrent…’. It can’t be a deduction if you presuppose it in the first instance.
