I will try to convert the PDF into a web page soon, in the meantime here is the abstract and the PDF attached.
Abstract: In this essay I will argue that Locke's theory of property doesn't support copyright as a natural right. Copyright must be justified instrumentally in terms of its contribution to our natural attributes and goals. These can be encapsulated in the concept of beneficial use, which I will briefly explore in terms of consuming, producing, sharing and learning. I will then conclude by arguing that such a Lockean theory of copyright provides an ideal basis for the free culture movement's critique of copyright, and their preferred system of property - a positive intellectual common.
