Yes, but it's not so much my idea, rather the ideas of others which I was reporting. I said in the article that “I am not attached to any of the ideas which follow, not claiming any of them as truth. They are just some possibilities which may shed some light on this issue”. Having said that, they do make sense if we are ever going to resolve the problem of God and evil.
Your question is, what this conception does for us, and how it makes the universe different than if we just stop at materialism? Your own suggestions are good: singularity of will, an immense plurality of will, Spirit with a goal, different spirits of various kinds that each have their own goals, and so on. I would add that we have learn to come to terms with the reality of evil as an aspect of the Ultimate Source (God); how can we each make the material world a better place, given that evil exists?
I don't believe therefore that Spirit is in opposition to our values, or is sadistic and wants suffering. It's just that the existence of evil at the material level is an inevitable consequence of manifestation. Don't forget that God told Adam and Eve not to eat of the tree. They disobeyed, and therefore have to face the consequences and seek solutions to atone for their error.
I'm aware of Leibniz and his ideas, although haven't read him. His concept of Monadology, I'm guessing, is similar to that of Theosophy, which also uses the term monad.
We can tie ourselves in knots trying to understand how spirit operates. In one sense spirit is eternal and unchanging (transcendent), and also the driving force behind manifestation and evolution (immanence). My best understanding for this is the position known as evolutionary panentheism.
Definitely against any justification of fascism, an obvious error, a manifestation of the highest will in a philosophical sense perhaps, but by deluded individuals at a very low level, with no spiritual understanding.
