Active inference offers a unified theory of perception, learning, and decision-making at computational and neural levels of description. In this article, we address the worry that active inference may be in tension with the belief–desire–intention model within folk psychology because it does not include terms for desires at the mathematical level of description. To resolve this concern, we first provide a brief review of the historical progression from predictive coding to active inference, enabling us to distinguish between active inference formulations (...) of motor control and active inference formulations of decision processes. We then show that, despite a superficial tension when viewed at the mathematical level of description, the active inference formalism contains terms that are readily identifiable as encoding both the objects of desire and the strength of desire at the psychological level of description. We demonstrate this with simple simulations of an active inference agent motivated to leave a dark room for different reasons. Despite their consistency, we further show how active inference may increase the granularity of folk-psychological descriptions by highlighting distinctions between drives to seek information versus reward—and how it may also offer more precise, quantitative folk-psychological predictions. Finally, we consider how the implicitly conative components of active inference may have partial analogues in other systems describable by the broader free energy principle to which it conforms.

We introduce a dynamic model for evolutionary games played on a network where strategy changes are correlated according to degree of influence between players. Unlike the notion of stochastic stability, which assumes mutations are stochastically independent and identically distributed, our framework allows for the possibility that agents correlate their strategies with the strategies of those they trust, or those who have influence over them. We show that the dynamical properties of evolutionary games, where such influence neighborhoods appear, differ dramatically from (...) those where all mutations are stochastically independent, and establish some elementary convergence results relevant for the evolution of social institutions.

Ship design needs to respond to and attract an ever more design conscious society. However, little research has been conducted into perceptions of beauty and pleasure and how such perceptions can be usefully absorbed into ship design. Aesthetic consideration, is seen as a distraction from the bespoke nature of the ship design process and is often avoided, second guessed or left for external consultancy. The ship design discipline requires the nurturing of its own aesthetic methods, for future development, and to (...) adapt some of the aesthetic ideals found in architecture, art and design. This paper argues that philosophy can be effective in interpreting what the passenger finds attractive and pleasurable. To illustrate the philosophical approach proposed, the `Elbe SWATH’ and the `Oasis of the Seas’ are investigated and compared using theoretical resources from the culturally focused philosophy of `Functional Beauty’. Conclusions suggest that the interpretation of the end users most valued appreciations can lead to design directives that deliver subjective qualities of beauty - beauty similar to those seen in the pure aims of the Elbe SWATH’s purposeful work craft, or comparable to nature’s beauty and purity in aim.

nature of personality and the structure of personality are distinguished, and the thesis that mainstream personality theories in psychology debate structure but not nature is illustrated with definitions. Mainstream theories assume that person ality is an inner determinant of behavior, but according to views in psychiatry, phenomenology and radical behaviorism the nature of personality is transactional. The theory of reinforcement schedules proposes general mechanisms of transac tions, and phenomenology gives particular transactions meaning. Interactionism, which locates personality in the person and (...) the situation, contributes measurement to transactionalism but its paradigmatic status is ambiguous because it implies an internal storage system for behavior.

Every living science, especially in its early stages, is compelled to devise fresh terms, either by coining new words or by giving new meanings to old ones. Unless and until these fresh terms become absorbed in the vocabulary of everyday speech, their unfamiliarity makes them a target for the shafts of the humourist. There can be no doubt that in the late fifth century B.C. literary criticism was still a new science. We can trace its beginnings in the treatises of (...) the Sophists, many titles of which have been handed down to us. Strepsiades' lesson in metric, though of itself amusing enough, would certainly gain in topical appropriateness if enacted at a time when such investigations were not only much in the air, but were still novel. And the whole ‘Agon’ of the Frogs, the character of which is forecasted in lines 796–802, depicts in the strongest colours the contrasted views of technician and inspirationist. We should therefore naturally expect a play of such a kind, written at such a time, to be full of technical jargon, barely understood by the ‘man in the street,’ and forming the object of his half-contemptuous amusement. That is, I believe, exactly what we do find, to an extent insufficiently recognized. Professor Radermacher, in his recent edition of the Frogs, has rendered valuable service by pointing out the frequent occurrence in that play of technical terms which meet us later in Dionysius of Halicarnassus and other critics. But I believe that technical language lurks unsuspected in many other passages, though the precise meaning may often be beyond recovery. (shrink)

Professor Linsay has called my attention to the need for an examination of these compounds, with a view to ascertaining whether they are ever used in the Singular by Latin writers, or always in the Plural. From a scholium, probably by Donatus, on Aen. X. 173: insula inexhaustis Chalybum generosa metallis, has come a gloss which appears in the Ansileubus Glossary in two forms: FR 205 Frofra : insula Tirreno mari in quo ferrifodina exercentur, RU 77 Rufa: insula Tirreni maris (...) in qua ferrifodina exercetur.
