This dissertation asks the question of how ownership over property in museums is decided. It concludes that for a range of candidate concepts of property, none of them oblige museums to repatriate artefacts unless we weaken Young’s theory to repatriate through how much artefacts are valued by a culture. However, this dissertation rejects the Ownership Argument as a defence for repatriation. To do this, it will be considering three options of how we understand ‘property’ through three scholars: Locke, Young and (...) Thompson. This dissertation will discuss the difference between cultural internationalism and cultural nationalism to flip the question, and attempt to defend a view that museums should retain the artefacts under their possession. To do this dissertation justice, this work has been interdisciplinary, exploring museums, law, applied philosophy, applied ethics, epistemic and metaphysical concepts, to discuss the ways in which repatriation is defended through property. It must be noted that property theories are in vast abundance, however, to keep the project manageable, it does not include prominent philosophers such as Nozick, Hobbes, and Rosseau. Although, given that the three concepts this dissertation discusses do not work, it seems unlikely that a different version would due to similar objections. (shrink)
