Looking for a metaphysical word I saw on these forums but now can't find

[Apparition of Jack]

It was something along the same train of thought as a Leibniz's "monad", in the sense that it referred to the basic "substances" of reality, but unlike monads (which refer to "one-in-one") it instead meant "two-in-one" or "both two-and-one." I really forgot what the word was, but I think it was something like "hologad" or something sounding like that.

Does anyone know what I'm talking about?

EDIT: Pre-emptive thank you for any replies!
