We are using monad in the functional programming sense? I thought Leibniz at first glance. I've never quite apprehended Leibniz's monads, so I put off trying to grok the post fully. An introduction to them would be useful.

I don't know much, but...

Leibniz's monads were an attempt to resolve the mind-body problem. Supposedly, monads are something like atoms, and something like souls. They don't interact with each other - all causality goes from God directly to the monads, not from one monad to the other - for example, perception is only accurate by God arranging for monads' perceptions to be accurate.

It seems like really incredibly strange metaphysics / theology to me.

I agree. Bertrand Russell explained it as due to Leibniz's beliefs about causality - one substance could not affect another substance. By a monad I just mean an elementary "thing" which can have mental states.
