Have you ever observed children at a playground, engaged in heated disputes over a cherished toy, all the while passionately screaming, “Mine!”? It might make you wonder: When do we claim ownership over something? Is it when we first possessed it? When we firmly grasp it in our hands? Or perhaps when we’ve worked for it?

As part of the opening of the POP Library at the WU Vienna, Bernadette Kamleitner and Michael Heller talk about Heller’s book “MINE!” and explore questions about ownership, such as what we can own and whether there is something we cannot own.
