Habere et usu: a short note on the name

Roman lawyers were unusually precise about what it means to own a thing, and they concluded that ownership is not one right but three. There is usus, the right to use it. There is fructus, the right to whatever it produces. And there is abusus, the right to consume it, alter it, sell it or destroy it. Split them apart and you get a whole vocabulary of arrangements that European law still runs on two thousand years later, the most familiar being usufruct, where one person holds the thing and another gets the good of it.

The part that has stayed with us is what the Romans made of usus specifically. It was not the junior member of the three. Under usucapio, set down in the Twelve Tables around 450 BC, continuous use over time did not merely demonstrate ownership. It created it. Hold a thing openly, use it as your own for long enough, and the law would eventually agree that it was. Use was not something you did with property. It was the proof that you had any.

“Habere et usu. To have and to use, as though the second were not a separate question from the first.”On the name

That distinction has become strange again, which is the only reason a Latin phrase ended up on a piece of audio software. A great deal of what we now call owning is really renting: an account you can be locked out of, a licence that renews, a library that exists on somebody else’s hardware and is yours in every sense except the ones that would matter if they changed their mind. You have it. Whether you may use it is a separate question, answered monthly.

So the name is a small argument, and it sets a test we have to keep passing rather than a story about our origins. The models sit on your disk. The audio you make is a file in your folder. When you are not connected to anything, none of it stops working, because none of it was ever reaching for us. A Roman jurist would have found that unremarkable, and would have been puzzled that we needed a word for it.
