I had trouble initially understanding the level 2 vs 4 distinction. It read as if level 2 was a willingness to lie about object-reality to bring about specific consequences, while level 4 involved similarly lying about object-reality to bring about specific, selfish consequences.
This didn’t seem like the most meaningful distinction, so I wondered what I was missing. These comments seem to describe level 4 as also being concerned with lying about social-reality, which feels elegant? However, we should be thinking of level 4 as being concerned with both object- and social-level reality?
In either case, this piece felt easier to digest to a total newbie than your initial links, so thanks for that!
