H. J. Nieboer, Slavery as an industrial system
“ Westermarck observes: “According to a common definition of slavery, the slave is the property of his master, but this definition is hardly accurate. It is true that even in the case of inanimate property the notion of ownership does not involve that the owner of a thing is always entitled to do with it whatever he likes; a person may own a thing and yet been prohibited by law from destroying it. But it seems that the owner’s right over his property, even when not absolute, is at all events exclusive, that is, that nobody but the owner has a right to the disposal of it. ”
