[Serious] An Argument Against Hedonistic Moral Realism

[Abaddon_ire]

Here's an argument against Hedonistic Moral Realism:

Premise 1: For hedonistic moral realism to be true moral realism as a whole has to be capable of being true.

Premise 2: Moral realism as a whole is only true if the foundation of moral values is something mind-independent.

Premise 4: According to hedonistic moral realism the foundation of moral values is pain and/or pleasure.

Premise 5: Neither pain nor pleasure is something mind-independent.

Conclusion: Hedonistic Moral Realism is false.

Thoughts on this argument?

It does not bode well when premise 3 is entirely missing.
