This paper aims to establish several interconnected points. First, a particular interpretation of the mathematical definition of information, known as the causal interpretation, is supported largely by misunderstandings of the engineering context from which it was taken. A better interpretation, which makes the definition and quantification of information relative to the function of its user, is outlined. The first half of the paper is given over to introducing communication theory and its competing interpretations. The second half explores three consequences of (...) the main thesis. First, a popular claim that the quantification of information in a signal is irrelevant for the meaning of that signal is exposed as fallacious. Second, a popular distinction between causal and semantic information is shown to be misleading, and I argue it should be replaced with a related distinction between natural and intentional signs. Finally, I argue that recent empirical work from microbiology and cognitive science drawing on resources of mathematical communication theory is best interpreted by the functional account. Overall, a functional approach is shown to be both theoretically and empirically well-supported. (shrink)

Hutto and Myin claim that teleosemantics cannot account for mental content. In their view, teleosemantics accounts for a poorer kind of relation between cognitive states and the world but lacks the theoretical tools to account for a richer kind. We show that their objection imposes two criteria on theories of content: a truth-evaluable criterion and an intensionality criterion. For the objection to go through, teleosemantics must be subject to both these criteria and must fail to satisfy them. We argue that (...) teleosemantics meets the truth-evaluable criterion and is not required to meet the intensionality criterion. We conclude that Hutto and Myin’s objection fails. (shrink)

The free energy principle is notoriously difficult to understand. In this paper, we relate the principle to a framework that philosophers of biology are familiar with: Ruth Millikan’s teleosemantics. We argue that: systems that minimise free energy are systems with a proper function; and Karl Friston’s notion of implicit modelling can be understood in terms of Millikan’s notion of mapping relations. Our analysis reveals some surprising formal similarities between the two frameworks, and suggests interesting lines of future research. We hope (...) this will aid further philosophical evaluation of the free energy principle. (shrink)

Over the last fifteen years, an ambitious explanatory framework has been proposed to unify explanations across biology and cognitive science. Active inference, whose most famous tenet is the free energy principle, has inspired excitement and confusion in equal measure. Here, we lay the ground for proper critical analysis of active inference, in three ways. First, we give simplified versions of its core mathematical models. Second, we outline the historical development of active inference and its relationship to other theoretical approaches. Third, (...) we describe three different kinds of claim -- labelled mathematical, empirical and general -- routinely made by proponents of the framework, and suggest dialectical links between them. Overall, we aim to increase philosophical understanding of active inference so that it may be more readily evaluated. -/- This the final submitted version of the Introduction to the Topical Collection "The Free Energy Principle: From Biology to Cognition", forthcoming in Biology & Philosophy.

This article establishes grounds on which attributions of information and encoding in animal signals are warranted. As common interest increases between evolutionary agents, the theoretical approach best suited to describing their interaction shifts from evolutionary game theory to communication theory, which warrants informational language. The take-home positive message is that in cooperative settings, signals can appropriately be described as transmitting encoded information, regardless of the cognitive powers of signalers. The canonical example is the honeybee waggle dance, which is discussed extensively (...) in the second and third sections. The take-home negative message is that signals are not always a consequence of coadaptation. The communication theory approach is just one end of a continuum explored more thoroughly by evolutionary game theory. The fourth and fifth sections explore this wider framework, as well as overturning some widely held misconceptions about information theory. (shrink)

Prominent views about representation share a premise: that mathematical communication theory is blind to representational content. Here I challenge that premise by rejecting two common misconceptions: that Claude Shannon said that the meanings of signals are irrelevant for communication theory (he didn't and they aren't), and that since correlational measures can't distinguish representations from natural signs, communication theory can't distinguish them either (the premise is true but the conclusion is false; no valid argument can link them).

In November 2022, OpenAI released ChatGPT, an incredibly sophisticated chatbot. Its capability is astonishing: as well as conversing with human interlocutors, it can answer questions about history, explain almost anything you might think to ask it, and write poetry. This level of achievement has provoked interest in questions about whether a chatbot might have something similar to human intelligence or even consciousness. Given that the function of a chatbot is to process linguistic input and produce linguistic output, we consider the (...) question whether a sophisticated chatbot might have inner speech. That is: Might it talk to itself, internally? We explored this via a conversation with ‘Playground’, a chatbot which is very similar to ChatGPT but more flexible in certain respects. We asked it questions which, plausibly, can only be answered if one first produces some inner speech. Here, we present our findings and discuss their philosophical significance. (shrink)

This thesis is an examination of claims about the risk of global catastrophe. I present examples of models of global systems that predict catastrophe, if certain conditions prevail, and I explain their goals as well as give some of their history. I present arguments concerning the conditions of a good prediction, and arguments concerning the predictive weakness of ecological models, to conclude that models of global systems generating predictions of catastrophe leave us uncertain as to the likelihood of catastrophe. ;Next, (...) I examine the problem of action in the face of this uncertainty. There are those who argue that policy-makers should not react to scenarios of catastrophe until the evidence for them is strong. On the other hand, there are those who adopt the 'precautionary principle', which advises that lack of scientific evidence for a claim should not be taken as a reason for exercising a lack of caution when the risk is high. ;Some authors have argued that if normal canons of rationality cannot recommend maximum caution, then we should adopt a rival rationality that emphasizes democratic and ethical values. I will critique this view and reject it for its failure to distinguish properly between epistemic values and action-guiding values. ;Other authors argue for the precautionary principle on the grounds that we have an ethical obligation to avoid catastrophe, whatever the practical costs. There are, as well, purely prudential reasons in favour of the precautionary principle. Using arguments parallel to those of Blaise Pascal and William James, I will argue that the prudential reasons for precaution are overwhelming and should convince those not already persuaded by ethical arguments. While models of global systems can only reveal possible futures and not probable futures, the catastrophic threats posed by such things as global warming, ozone depletion, or population increase, though not firmly established, represent what James would call 'live options'; that is, they present us with a possibility that is at least plausible and that forces us to make momentous decisions. I conclude that we cannot afford to risk catastrophe despite the high costs this decision will involve. (shrink)

A scale free communication network in a power network is provided. The scale free communication network comprises a plurality of distribution devices communicatively coupled to each other in a power network that include a protection device and a controller coupled to each of the plurality of distribution devices in the power network. The controller identifies a plurality of isolated distribution devices. The controller further restores the plurality of isolated distribution devices in the power network by automatically activating the tie-switch in (...) the power network. The controller also computes reliability indicators for each of the restored distribution device in the power network. Furthermore, the controller identifies critical distribution devices in the power network based on the computed reliability indicators and establishes a scale free communications network within the power network based on the identified critical distribution devices.

With the tertiary education mantra of creativity, critical thinking and innovation in mind, we consider the critical-creativity of error. Taking the university to model social orthography, or ‘correct writing’, according to the norms of disciplines, we consider the role of error in the classroom. Looked at another way, error questions the norms governing norms and the instability of disciplinary grounds. Beyond correction, error involves a mis-taking, or taking another way. Tracing the origin of error we are able to reconstruct the (...) social world in terms of which it is conceivable for a mistake of any kind to have been made. The university, we find, withholds worlds which are not new but are sources of creativity, and constitutes a pluriversity or poly-versity. (shrink)

Field-Programmable Gate Arrays (FPGAs) have emerged as an attractive means of implementing logic circuits, providing instant manufacturing turnaround and negligible prototype costs. They hold the promise of replacing much of the VLSI market now held by mask-programmed gate arrays.

This study investigated how learner support services at the University of Calabar predict business education students' preparation for online learning. Two specific objectives were established, two research questions were posed, and two null hypotheses were developed and tested at a significant level of .05. Pertinent literature was reviewed. The population consisted of 147 University of Calabar 400-level business education students. This population also formed the sample using a census process. Data were gathered using a structured questionnaire with 40 items that (...) were validated by five specialists from the University of Calabar. Cronbach Alpha statistics were used to establish the questionnaire's reliability, yielding reliability coefficients of 0.88 and 0.85 for the independent sub-variables and dependent variable, respectively. Following the administration of the questionnaire, the data collected was analyzed using linear regression analysis to test the hypotheses. The results show that academic and technological support services strongly predict business education students' preparation for online instruction at the University of Calabar. Based on these findings, the study recommends that lecturers, counsellors, and academic technicians should encourage students to participate in digital education by offering intellectual, emotional, and other support services.

Presents close analysis of eight of Francis Bacon's texts in order to investigate the relation of his religious views to his instauration. Attempts to correct the persistent misconception of Bacon as a secular modern who dismissed religion in order to promote the human advancement of knowledge"--Provided by publisher.

This ambitious and important book, first published in 2001, provides a truly general account of Francis Bacon as a philosopher. It describes how Bacon transformed the values that had underpinned philosophical culture since antiquity by rejecting the traditional idea of a philosopher as someone engaged in contemplation of the cosmos. The book explores in detail how and why Bacon attempted to transform the largely esoteric discipline of natural philosophy into a public practice through a program in which practical science (...) provided a model that inspired many from the seventeenth to the twentieth centuries. Stephen Gaukroger shows that this reform of natural philosophy was dependent on the creation of a new philosophical persona: a natural philosopher shaped through submission to the dictates of Baconian method. This book will be recognized as a major contribution to Baconian scholarship, of special interest to historians of early-modern philosophy, science, and ideas. (shrink)

Francis Hutcheson's An Inquiry Into the Original of Our Ideas of Beauty and Virtue, published in 1725, arguably contains the first broadly utilitarian theory of rights ever formulated. In this essay, I argue that, despite its subtlety, there are crucial lacunae in Hutcheson's theory. One of the most important, which Mill seeks to repair, is that his theory of rights lacks a conceptually necessary companion, namely, a corollary account of obligation. Hutcheson has no theory of fully deontic obligations, much (...) less an account of the relational obligations that, as Hohfeld famously argued, are the conceptually necessary correlates of claim rights of the kind Hutcheson wishes to theorise. Like Hume, Hutcheson subversively redefines ‘obligation’ as a motive of self-interest or the approval of morally good motives by moral sense. This leaves Hutcheson without any account of the obligations that are the necessary correlates of claim rights. Mill does significantly better on this score but ends up giving a pragmatic ‘reason of the wrong kind’ for rights and obligations. Hutcheson thus begins a line of thought shown by him to have been powerless to ground rights without independent deontic premises from the start. (shrink)

Professor Gostin is a leading authority on health law, whose writing and teaching are among the most authoritative in the United States, as exemplified by his recent work, Public Health Law: Power, Duty, Restraint. Gostin's article in this issue of the Journal of Law, Medicine & Ethics pays homage to Jonathan Mann by expressing the debt he feels toward this extraordinary doctor and public health official with whom he had collaborated on several projects.As many will remember, Mann held (...) high-level positions at the Centers for Disease Control and worked on AIDS research in Central Africa before setting up the World Health Organization's Global Programme on AIDS, which he ran from 1986 to 1990. Thanks to his profound commitment and consummate communication skills, he achieved the unprecedented feat of raising the budget within two years to almost $100 million from the initial set-up of “himself, a secretary, and one typewriter,” as described by Daniel Tarantola.

Mathematics, even more than the other sciences, is often presented as essentially unique, as if it could not be any other way. And yet, prima facie alternative mathematics are all over the place, from non-Western mathematics to mathematics based on nonclassical logics. Taking inspiration from Robin Dembroff’s analysis of critical gender kinds, and from Andrew Aberdein and Stephen Read’s analysis of alternative logics, in this paper I will introduce a practice-centered framework for the study of alternative mathematics based on (...) the notion of critical math kind. After sketching a model of mainstream mathematics, I will provide examples of how deviation along several distinct dimensions can occur, and how deviations can vary in their gravity. I will then discuss how the framework can be used to think of questions concerning the alternativeness status and philosophical implications of alleged alternative mathematics, and help us in identifying alternatives that suit our purposes.
