And no. The 9 noble virtues are a modern idea that attempts to cram and entire worldview into 9 pigeon holes. I have nothing against the idea of them, because they are good things to live by. But I don't subscribe to them, no.
I am a Norse Heathen, leaning more into the direction of stone age animism/shamanism than towards modern-day Asatru.
Nine Noble Virtues are a modern construct, formed as a sum up of the Havamal and as such, rather simplistic, adjusted of course to their target "costumers" - the Americans who subscribed to Stephen McNallen's reconstruction of Norse beliefs.
I prefer the original source.
Yes and no. The NNV are a modern innovation but a good summation of the ethics, but its best to go to the source material for a better understanding of how Heathen ethics functions.
