Lockean approaches to property take it that persons can unilaterally acquire private ownership over hitherto unowned resources. Such natural law accounts of property rights are often thought to be of limited use when dealing with the complexities of natural resource use outside of the paradigm of private ownership of land for agricultural or residential development. The tragedy of the commons has been shown to be anything but an inevitability, and yet Lockeanism seems to demand that even the most robust common (...) property arrangements be converted to privatized units. This often motivates a move away from natural law in the moral analysis of property rights. I argue however that it is not the deontological nature of Lockean principles that are at fault, but rather the manner of their application. Lockean theory often exhibits a bias in favour of private property: assuming that only private property can protect one’s interest in autonomy, and therefore asserting that each individual has a power of private acquisition. Starting with a claim against interference however enables us to mould the appropriate property rights to each individual’s particular interest in autonomy. This sometimes leads to private ownership, but often leads to various forms of commons. (shrink)

When we seek a fuller understanding of individual liberty including its relational character, we confront a conundrum. The evident advantages of a single individual possessing liberty cannot be simply transferred to a greater number of beneficiaries. This conundrum is confronted with the resources of Hohfeld's analytical framework, developed specifically to elucidate the practical outworkings of interpersonal relations within the law. Attention is also paid to concerns expressed by von Wright over a representation of liberty (permission) within the resources of standard (...) deontic logic which fails to address its social aspect. The aggregate level of the Hohfeldian scheme is employed to represent a complete picture of liberty, but one that cannot guarantee benefits for a plurality of holders. The conclusion is reached that in order to extend the advantages of individual liberty to all, something other than liberty is required. (shrink)

This paper presents a new challenge for libertarianism. The problem, in a nutshell, is that libertarianism appears to self-destruct in cases where conjoined twins—who share body parts—disagree over what to do with them. The problem is explored, and some solutions are proposed. The verdict is that accepting any of them will make libertarianism harder to defend.

Most philosophical accounts of human rights accept that all persons have human rights. Typically, ‘personhood’ is understood as unitary and binary. It is unitary because there is generally supposed to be a single threshold property required for personhood. It is binary because it is all-or-nothing: you are either a person or you are not. A difficulty with binary views is that there will typically be subjects, like children and those with dementia, who do not meet the threshold, and so who (...) are not persons with human rights, on these accounts. It is consequently unclear how we ought to treat these subjects. This is the problem of marginal cases. I argue that we cannot resolve the problem of marginal cases if we accept a unitary, binary view of personhood. Instead, I develop a new non-binary personhood account of human rights, and defend two main claims. First, there are many, scalar properties, the having of which are conducive to personhood. Second, different subjects have different human rights depending on which of these properties they have, and what threats apply to them. On my view, and contra most existing accounts, most marginal cases have some degree of personhood and are entitled to some human rights. (shrink)
