How important are each of Haight's Five Foundations of Morality to you?

[Whateverist]

I just watched the video. Fascinating!

The part at the end sounds just like my passionate insistence that morality is entirely subjective. There aren't good and bad actions. There are judgements of actions. You need to try and convince people of why your system is better. What are you trying to achieve? Why is that important? How are you achieving it? The biggest problem is to simply assume anyone who doesn't agree with what you think morality (broadly) is, must be excluded from the discussion. You enter an echo chamber. This is why I always start from first principles.

Coming back to the fifth area, purity, I'm still rather confused. It's pragmatic to feed your body with healthy, "pure" things, and to do wholesome activities. This doesn't seem to have much to do with morality, but rather managing your health. I find the concepts of purity and sanctity to be dogmatic; labels which are put on certain things in order to remove them from criticism or discussion. Maybe there's more going on here than I'm understanding.

My initial reaction was exactly the same about purity until I linked it to authenticity.  Thump talks about having a "bull shit detector".  People who can't pass it probably aren't being truthful with you, have a hidden agenda or are just compulsive about winning approval. One way to say it is they aren't being genuine.  I think this is a perfectly reasonable application of "purity" which has nothing to do with holiness.  And I find that it is already there in my moral judgement regardless of what I may think about it.  I judge myself poorly when I hold back to protect someone's feelings and my opinion of others is definitely affected by it.  It definitely is an aspect of moral behavior.
