The hierarchical ordering of all existence from God to minerals.
The Great Chain of Being ranks all existence in one continuous hierarchy: God at the summit, then angels, humans, animals, plants, and minerals, descending without gaps to base matter. Every being holds a fixed rung, and the chain is full — no link missing, no rank empty.
It unlocks the medieval and Renaissance instinct toward total order: a single scale on which everything has a place and a degree, and where one's duties follow from one's position. Though we have abandoned its rigidity, it remains the ancestor of every taxonomy and org chart — the deep desire to rank the world completely.
