I defend the cosmopolitan instrumentalist theory of secession, according to which a group has a right to secede only if this would promote cosmopolitan justice. I argue that the theory is preferable to other theories of secession because it is an entailment of cosmopolitanism, which is independently attractive, and because, unlike other theories of secession, it allows us to give the answers we want to give in cases like secession of the rich or secession that would make things worse for (...) minorities. I defend the view against the objections that it allows for colonialism and annexation, that it is not a distinct theory, and that it is impractical. (shrink)

This paper argues that the Lockean proviso can be utilized as a relevant principle of justice for food security under global climate change. Since reducing GHG emissions is key to enhancing food security, we suggest a global food security scheme that systematically allots, among all people, access to GHG sinks in food systems impacted by global climate change. For consideration of the scheme, it is important to have a principle of justice. Furthermore, it should incorporate the value of fairness. A (...) relevant principle of climate justice for food security should meet the following criteria: (1) the parties concerned under the scheme are states; (2) fairness does not undermine the requirement that the basic needs of all people must be met; (3) when determining fair burdens, a fair distribution of the rights to use GHG sinks should be sensitive both to each state’s responsibility for its GHG emissions and to (4) each state’s effort to reduce such emissions. With them in mind, first, we argue that the Lockean proviso can provide legitimate guidance for each state. Second, the Lockean proviso reasonably enjoins that a state has a right to a food system that secures its citizens’ basic needs, and a duty to meet the basic needs of other people. Third, the Lockean proviso can be deployed as a principle of both global justice and intergenerational justice for food security. Finally, the Lockean proviso enables us to count the reduction of GHG emissions by each state as “the fruits of its labors”. (shrink)

RésuméSelon le scepticisme anarchiste d'A. John Simmons, il n'y a pas d'obligation d'obéir à la loi dans l’état actuel des choses, car les obligations légales n'ont de légitimité que lorsqu'elles sont volontairement contractées par la plupart ou de nombreux citoyens. Cependant, la sensibilité de Simmons à la diversité des raisons et à la possibilité d'un conflit non résolu suggère une position alternative pluraliste. Celle-ci montre que les fondements de l'autorité légitime sont pluriels et incluent la justice distributive. En outre, même (...) les obligations contractées volontairement peuvent être annulées par des raisons contradictoires, comme lorsque nous sommes liés par le devoir à un régime injuste. (shrink)
