Leibniz's Monadology

[Sethomas]

I'm a ways into this right now, and I absolutely love his work. My own theory is very very similar to his, so it just makes me curious as to why he's been overlooked so much. The central problem in his thinking is that he posits the soul as having only passive abilities of perception, and thus he has to make such contortions of logic as "the evil of Judas is more than balanced by the good of the world". Well, I agree with that, but Judas remains SOL for being predetermined to betray Christ with no real culpability attached to his own soul.

Anyone else have thoughts on Leibniz?
