We defend the moral and legal right to secede in accordance with plebiscitary theory. Our paper has three main goals. First, by offering a schematic characterization of plebiscitary theory, the main arguments in its favour (and the main objections to them), we contribute to clarify the structure of this complex debate. Second, we stress the point that, if the moral right to secede is established, the resistance for its inclusion into positive law is unjustified. Finally, by addressing old and new objections to plebiscitary theory, we hope to make a compelling case for a wider recognition of secessionist rights.

The goal of this essay is to put forward an original theory of artifact function, which takes on board the results of the debate on the notion of biological function and also accommodates the distinctive aspects of artifacts. More precisely, the paper develops and defends the Dual-Aspect Theory, which is a monist account according to which an artifact’s function depends on intentional and reproductive aspects. It is argued that this approach meets a set of theoretical and meta-theoretical desiderata and is superior to alternative views.

Recent research on bacteria and other microorganisms has provided interesting insights into the nature of life, cooperation, evolution, individuality or species. In this paper, I focus on the capacity of bacteria to produce molecules that are usually classified as ’signals’ and I defend two claims. First, I argue that certain interactions between bacteria should actually qualify as genuine forms of communication. Second, I use this case study to revise our general theories of signaling. Among other things, I argue that a plausible requirement for a state to qualify as a signal is that it is a minimal cause.
