Your argument is unsound. Obviously so. My argument is sound.
Moral values are not made of our values. Again, for the umpteenth time, if they were, then if you valued raping someone necessarily it would be good for you to rape them. That's absurd. No-one sensible thinks that's correct. To think that's correct is as silly and unworthy of rational respect as the view that if you think 3 x 2 = 90 then it is.
If you value raping someone - guess what, that doesn't mean it is good for you to rape them.
If you value me raping someone - guess what, that doesn't mean it is good for me to rape them.
If you value someone else raping you - guess what, that doesn't mean it is good for someone to rape you.
And so on and so on.
Your view is absurd. Outrageous. It has nothing - nothing - to be said for it. That you hold it - that it exists in your head - is not evidence it is true.
Your view is demonstrably false. This argument demonstrates its falsity - this argument that has a first premise that cannot coherently be denied and a second premise that is self-evidently true to everyone who isn't determined that Bartricks is wrong because Bartricks is mean and that's how the world works:
1. If my valuings are moral values, then if I value something necessarily it is morally valuable
2. If I value something it is not necessarily morally valuable
3. Therefore, my valuings are not moral values.
That's a valid argument. It always was valid. When you thought it wasn't valid, it was valid.
When you thought the first premise was not expressed correctly - and it was and is expressed correctly, unlike your first premise which is false - it was valid.
It is valid. It's premises are true beyond all reasonable doubt. It is not a remotely controversial argument.
But when coupled with another argument - the argument that moral values must be someone's, it gets us all the way to divine command theory.
And you - and most others here - don't like that. And because you seem to have the mentality of six year olds and think that if you don't like something it isn't true, you reject it.
But the whole argument is valid. And its premises appear to be true beyond reasonable doubt.
The only threat to it - the only thing that suggests otherwise - is the Euthyphro argument. That argument has the negation of my conclusion as its conclusion and premises that appear to be as strong as mine.
But no-one has pressed it!
