In terms of validity in Kripke frames, a modal formula expresses a universal monadic second-order condition. Those modal formulae which are equivalent to first-order conditions are called \emph{elementary}. Modal formulae which have a certain persistence property which implies their validity in all canonical frames of modal logics axiomatized with them, and therefore their completeness, are called \emph{canonical}. This is a survey of a recent and ongoing study of the class of elementary and canonical modal formulae. We summarize main ideas and (...) results, and outline further research perspectives. (shrink)

In this study, W. J. Waluchow argues that debates between defenders and critics of constitutional bills of rights presuppose that constitutions are more or less rigid entities. Within such a conception, constitutions aspire to establish stable, fixed points of agreement and pre-commitment, which defenders consider to be possible and desirable, while critics deem impossible and undesirable. Drawing on reflections about the nature of law, constitutions, the common law, and what it is to be a democratic representative, Waluchow urges a different (...) theory of bills of rights that is flexible and adaptable. Adopting such a theory enables one not only to answer to critics' most serious challenges, but also to appreciate the role that a bill of rights, interpreted and enforced by unelected judges, can sensibly play in a constitutional democracy.

Let all finite sequences of letters of the English alphabet be ordered serially so that shorter sequences precede longer ones, and sequences of the same length are ordered alphabetically. Thus, an ordinal number is assigned to every possible English sentence of finite length. Among these numbers, some--call them S-numbers --will be the numbers of sentences which are instructions for writing down an infinite sequence of numbers. Now, it is impossible to state, in an English sentence of finite length, a generally (...) applicable procedure for determining whether an arbitrarily given number is an S-number. (shrink)

Computational functionalism [5] fails to understand the embodied and situated nature of behaviour by taking steady state functions as theoretical primitives, and by interpreting cognitive behaviour from a language-like, observer dependant framework without a naturalized normativity. Evolutionary functionalism [28, 27], on the other hand, by grounding functional normativity on historical processes fails to give an account of normative functionality based on the present causal mechanism producing behaviour. We propose an alternative autonomous dynamical framework where functionality is defined as contribution to (...) self-maintenance [15, 10, 35] and normativity as satisfaction of closure criteria. We develop this framework by a set of formal definitions in the framework of dynamical system theory and propose the hypothesis of an homeostatic-plasticity [31, 40] based general purpose value system as an internalized normative mechanism that selects between internal state trajectories to produce adaptive functionality under different environmental conditions. To test the hypothesis we develop a simulation model where lower level specifications of a control arquitecture (an homeostatic plastic DRNN) give rise (through a simulated evolutionary process) to adaptive behaviour in a foraging task where food sources can be poisonous or profitable. Analysis of the evolved agent show that plastic changes occur when the agent produces salient adaptive interactions, those plastic changes determining the adaptive strategy. The embodied and interactive adaptive functionality is dynamically analysed, illustrating the autonomous dynamical framework. (shrink)
