The argument from morality is not a valid argument for the existence of (a) god(s)

===Definitions===

The argument from morality is argued in several forms, however the gist of the position could be summed up as follows (from the Stanford Encyclopedia of Philosophy):

P1: Moral normativity is best explained through the existence of authoritative moral rules.
P2: Authoritative moral rules must be promulgated and enforced by an appropriate moral authority.
P3: The only appropriate moral authority is God.
C: Thus, given that there is moral normativity, there is a God.[1]

God(s) will be defined in the traditional theistic meaning, where God is omnipotent, omniscient, and benevolent.

An argument is valid "when the conclusion is entailed by, or logically follows from, the premises."[2] A valid argument may be contrasted with a sound argument. An argument is sound when it is "valid and all its premises are true."[2] For the moral argument to be valid, I must only show that IF the premises are all true, THEN the conclusion is logically necessitated.

===Argument===

Premise 1: An argument is valid IFF its premises (if true) necessitate its conclusion.-- From the definition of a valid argument

Premise 2: The premises of the moral argument necessitate its conclusion IFF they are true.

Conclusion: The moral argument is valid.

As can be seen, this argument is clearly valid. Considering the definition of a valid argument, the validity of this argument would be shown if the two premises on which it is composed are shown to be true. On the soundness of my argument, the moral argument itself can be shown rather intuitively to be valid. IF authoritative moral rules best explain moral normativity, and authoritative moral rules entail an appropriate moral authority, and God is the only appropriate moral authority, THEN God exists. Whether all these premises are sound or not is still a matter or debate of course and is not the proper subject matter of the resolution.
