Actually somewhat surprised that the correct answer doesn't show up in this thread among all the joke and wrong answers.

Metaphysics is structure. That's all. It's not that complicated. https://twitter.com/lastpositivist/status/1245626181640048642

Metaphysics isn't prior to science; on the contrary, it is central to all theory-building.

Metaphysics isn't exclusively concerned with "intrinsic natures". Insofar as that concept has a reference at all, it refers to another structure.

Metaphysics is politics because how we talk and think about structures has direct consequences for the worlds we build and for how we treat each other.

Metaphysics is politics because theory is never idle. https://twitter.com/eripsa/status/1224851830137597952

Mathematics is universal metaphysics. It concerns structures in their most general sense. No surprise, it is also a constant companion to theory/world-building, and is ubiquitous in the sciences.

But the logical positivists rejected "metaphysics" but they loved structure and math and science! What's up with that?

To them "metaphysics" means "bad structures", which are the ones that can't be verified by empirical science, their template for "good structure".

The problem is that structures are ubiquitous! From a little evidence it's possible to draw lots of structural conclusions. Some of those conclusions are reasonable and other's aren't, and telling the difference is hard. "Verification" was an attempt to describe this boundary.

I'm sympathetic to the positivist's position. I also called myself a "behaviorist" for most of grad school, rehearsing the standard arguments.

But calling something "metaphysics" as blind rejection is just the flipside of yelling "science" as blind acceptance.

Eventually, I decided to stop worrying and treat all structural claims as metaphysics.

The only real issue: is your metaphysics any good?
