Proverbs 21:30

Proverbs 21:30 states "There is no wisdom, no insight, no plan that can succeed against the Lord." 

This verse is really about the futility of going against divine authority, but for some reason it reminds me of a common implication that if there is no final authority, then anything is permitted.  This is a common argument in apologetics I believe.

And vacuous truths, which I mentioned not too long ago, look somewhat similar.  If the premise is false, then any conclusion is permitted.

So if there isn't a God, apologists would say anything goes using their usual arguments.

But also if there is one, and we declare there to not be, again we'd reach the conclusion that anything goes, using a vacuous truth argument.

In declaring God as a falsehood, whether accurate in actuality or not, apologists are going to reach the idea that anything goes. 

Certainly not a brilliant observation or anything, but a questionable and minor observation easy to put in a personal journal for a day.
