Emotions are intrinsically good and bad

[Transcended Dimensions]

Hedonism is an axiomatic value statement.  It's not the conclusion of an argument, it's the premise.

As premises go, it has problems.  The first is that it's self defeating.  Pleasure seeking may not actually be the best way to secure pleasure.  It often yields misery instead.

Then your non hedonistic values are also just a premise as well.  That all goes back to what I said earlier.  There are those types of situations which we know are true such as the fact that, if I drink poison, that would be lethal to me.  But then there are other types of situations where there is no proving who is right and who is wrong.  These types of situations are where we just argue back and forth and it just gets nowhere.
