Full Idea
Perhaps notions of necessary and sufficient conditions, and counterfactual considerations, are in some way grounded in awareness of ourselves as active interveners and experimenters in the world, not passive spectators.
Gist of Idea
There may only be necessary and sufficient conditions (and counterfactuals) because we intervene in the world
