“Metaphysics: what it means for there to be something rather than nothing, why there is something rather than nothing, and why there is some specific thing rather than some other specific thing or nothing;
types of communities: power and role imbalances both qualitative and quantitative;
lexical semantics: laws of non-contradiction and excluded middle, at least for existent entities;
classification systems: boundaries and the different entities and differences between entities in opposite/different positions. ” Ned Andrews
One thing I like about chemistry is that it’s time-based. In many areas of inquiry you can ignore time or have time easily reversible without consequences but not chemistry.
This particular thing I’m working on (which is only the past 3 weeks – I didn’t expect this particular iteration of my ontological quest to hold my interest as long as it has — usually I only stay on a particular facet of a thing for 1-5 days at most) — doesn’t have equilibrium because I was restricting myself nearly exclusively to “Wikipedia categories”, forcing myself to ignore a lot of potentially interesting things to focus on “groupings” that are in common usage.
So, there is no category: Equilibrium. This page, “list of types of equilibrium” is under category: “Science related lists” – one I haven’t seen before.
