"Things" with some bounded shape or form (or other properties) may be related to perceptual apparatus.
We see, or hear or smell or taste or feel, etc., the boundaries, emissions, or other perceptible manifestations of objects or phenomena. If you will, those are their interfaces.
As in other domains, an interface may reveal, or conceal, some more complex back-end, inner working, or larger system.
I've been thinking on Aristotelian categories over the past couple of years. Thought occurs that all of them are relations, though with varying degrees of dependence on the observer.
Related, a ~1835 essay on value by W.F. Lloyd notes that all value is relative. That's not a universally held view, but is, I believe, correct.
