1. The Gathas was written in Avesta, not in English. So there is definitely no good or bad in The Gathas. And asha means "constructive mentality" and druj means destructive mentality". What is about that that is so hard for you to understand?
2. Since you so adamantly insist that Zoroastrianism is not relativistic, against every Zoroastrian scholar there is, can you please give me an example of ANY moralistic commandment anywhere in The Gathas taht would prove your point?
3. As I have told you before: It would be helpful if you suggest an alternative rather than just negating what others propose on this forum. Otherwise, our discussions are not getting anywhere. Calling for others to oppose me borders on sociopathy and not on intelligence or integrity of debate, dear George! Don't call on others, make your own propositions, make your own arguments instead, just don't only negate!
I accept your description of Zarathushtra being an ethicist, but I can't understand WHY ethics must be relativistic. We are different persons, with different ideas and different standards, but does this mean that "good" could be defined differently for all of us? If you accept Mehr's definition about "good" then there is no need for relativity. Something can be dynamic without being relativistic. Evolution of the species is an example of a dynamic state: species evolve and there is nothing relativistic about it.
There are no commandments due to the principle of Asha, the eternal law of Mazda. We just warned, but the decision is left to us.
I can't read avestan, so I'd like to hear it from the experts: in the Gathas isn't there any mention to good or bad? I've always thought that the motto of the 3Gs belongs to Zarathushtra. I would really like to hear more on this.
It's all inside our heads, but we are related to other humans too, so for an action to be good or bad, it's dependent to the effect it has on all of usâ€¦ It's all about actions as well, not just about thoughtsâ€¦
