Latin monasmonad-unitfrom Greek frommonossinglemen-4 in Indo-European roots
Each monad works out necessary results, but these flow from its own nature; and so in a sense it is free.
For the soul, by its nature as a single monad indestructible and, therefore, immortal, death meant only the loss of the monads constituting the body and its return to the pre-existent state.
But this idea involves the further conception of Leibnitz, that of a pre-established harmony, by which the Creator has taken care to arrange the life of each monad, so that it agrees with that of all others.
The more Spinozistic side of Leibnitz's thought - God as Monad of Monads - is a theistic postulate if hardly a theistic proof.
Reciprocal action is explained away into a " preestablished harmony " between every monad and all others.
