At the basis of modern natural law theories, the concept of the suum, or what belongs to the person (in Latin, his, her, its, their own), has received little scholarly attention despite its importance both in explaining and justifying not only the genealogy of property, but also that of morality and war.1 In this paper I examine Hugo Grotius's what it is, what things it includes, what rights it gives rise to and how it is extended in the transition from the state of nature to civil society. I then briefly point out how bringing this concept back to the fore could help to illuminate the current discussion on the foundations of basic human rights, and to evaluate cases where these seem to clash with property rights.

Given the grim global statistics of extreme poverty and socioeconomic inequalities, moral and political philosophers have focused on the duties of justice and assistance that arise therefrom. What the needy are morally permitted to do for themselves in this context has been, however, a mostly overlooked question. Reviving a medieval and early modern account of the right of necessity, I propose that a chronically deprived agent has a right to take, use and/or occupy whatever material resources are required to guarantee her self-preservation, or the means necessary to acquire them. There are three individually necessary and jointly sufficient conditions: the need is basic, the claimant does not violate other equally important moral interests, and it is a last resort. I present two recommendations to be followed by the claimants, and offer some examples where this principle may be applied today. I reply to the objections that understanding the right of necessity in this way kills its intuitive plausibility, and that it is a remedy worse than the disease. I conclude that, while not the best solution for the problem of global poverty, the exercise of this right should be accepted if we believe in the human right to subsistence.

Narrowly understood, veganism is the practice of excluding all animal products from one’s diet, with the exception of human milk. More broadly, veganism is not only a food ethics, but it encompasses all other areas of life. As defined by the Vegan Society when it became an established charity in the UK in 1979, veganism is best understood as “a philosophy and way of living which seeks to exclude – as far as is possible and practicable – all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of humans, animals and the environment”. There are two main moral justifications for veganism, both of which rely on a common assumption: that sentience, i.e., the capacity to feel pleasure and pain, is the necessary and sufficient trait to be morally considerable. In what follows, I present these two justifications and a third one which, although less popular, captures some core intuitions among vegans. I then present a challenge faced by veganism and two arguments that reject it as discriminatory, and briefly conclude.

Forty years ago, in his landmark work A Theory of Justice, John Rawls depicted a just society as a fair system of cooperation between citizens, regarded as free and equal persons. Justice, Rawls famously claimed, ought to be “the first virtue of social institutions.” Ever since then, moral and political philosophers have expanded, expounded or criticized Rawls’s main tenets, from perspectives as diverse as egalitarianism, left and right libertarianism, and the ethics of care. The most important and influential views in this ‘post-Rawlsian’ era constitute the focus of this volume, which seeks to give a general picture of the main strands in contemporary justice theorizing, as well as addressing more recent developments, especially regarding methodological issues. How to build a theory of justice and how to delineate its proper scope; the relationship between justice and equality, justice and liberty, and justice and desert; and the critique of the Rawlsian paradigm especially from the feminist perspective and from the growing strand of non-ideal theory are the main topics addressed in this selection of essays.
