Williamson defines contingentism as the opposite of necessitism and both as follows: Call the proposition that is necessary what there is necessitism and its negation contingentism. In a slightly less compressed form, necessitism says that necessarily everything is necessarily something; still more long-windedly, it is necessary that everything is such that it is necessary that something is identical with it. ( Modal Logic as Metaphysics , 13 - Oxford UP). In still other words, necessitism takes existence as necessary while contingentism has that what exists is contingent on something and could be otherwise. Following contingentism, what exists could be dependent on whatever else exists. This is the sort of contingentism a monadological approach (which I would find in Leibniz but also on Tarde, Whitehead, Latour and maybe others) would embrace. In fact, contingentism seems to follow from Leibniz' law - things are what they are necessarily but they don't exist necessarily (...
