The model is physical solidity—the real counter-force from our acts of pushing our own body (parts) against “things”—where the thingyness is just the experience of resistance.
Imagine trying to learn “thing” qua “mass” by watching videos of billiards games. Movement, yes. Mass, no. Force, yes. But not the force that we pressure-knowing ones cognize. You have to press against with desire in order to generate the real semantic meat of mass and thing.
