Can you define 'own' without using another word for it, (belong, possess, etc.?) (And I mean 'own' as in possess, not in 'I can do it on my own.') 'Cause I know everyone sort of knows what it means and entails and whatever. But, what does it really mean to 'own' something? And how can you even 'own' something? (I unserstand it's an abstract idea.)
Alan Soble's general points about definition are well taken. However, here's a start to defining own in other terms: To own an item is to have the right, perhaps within limitations, to decide its fate. This leaves it open that ownership might be a natural relation or a socially constructed one, depending on whether the rights constitutive of ownership are natural or socially constructed. It also leaves it open in what circumstances one has such rights.
