Single Idea 2963

[filed under theme 1. Philosophy / F. Analytic Philosophy / 3. Analysis of Preconditions ]

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
