In this paper I offer an analysis of Plotinus’ argument for the existence of a quasi-psychic entity, the so-called ‘trace of soul’, that functions as an immanent cause of life for an organism’s body. I argue that Plotinus posits this entity primarily in order to account for the body’s possession of certain quasi-psychic states that are instrumental in his account of soul-body interaction. Since these quasi-psychic states imply that an organism’s body has vitality of its own , and Platonic souls (...) are no part or aspect of any body, Plotinus draws the conclusion that the soul must be a cause of the body’s life by imparting a quasi-psychic qualification to it. In so doing, Plotinus introduces elements of hylomorphism into Platonist psychology, and addresses a problem for the animation of the body that Platonic soul-body dualism may plausibly be thought to face.

Information providing and gathering increasingly involve technologies like search ‎engines, which actively shape their epistemic surroundings. Yet, a satisfying account ‎of the epistemic responsibilities associated with them does not exist. We analyze ‎automatically generated search suggestions from the perspective of social ‎epistemology to illustrate how epistemic responsibilities associated with a ‎technology can be derived and assigned. Drawing on our previously developed ‎theoretical framework that connects responsible epistemic behavior to ‎practicability, we address two questions: first, given the different technological ‎possibilities available (...) to searchers, the search technology, and search providers, ‎who should bear which responsibilities? Second, given the technology’s ‎epistemically relevant features and potential harms, how should search terms be ‎autocompleted? Our analysis reveals that epistemic responsibility lies mostly with ‎search providers, which should eliminate three categories of autosuggestions: those ‎that result from organized attacks, those that perpetuate damaging stereotypes, and ‎those that associate negative characteristics with specific individuals.‎.

How to accept a conditional? F. P. Ramsey proposed the following test in (Ramsey 1990).(RT) If A, then B must be accepted with respect to the current epistemic state iff the minimal hypothetical change of it needed to accept A also requires accepting B.

Conceptual engineering is commonly characterized as the method for assessing and improving our representational devices. Little has been said, however, on how best to construe these representational devices—in other words, on what conceptual engineering should be all about. This paper tackles this problem with a basic strategy: First, by presenting a taxonomy of the different possible subject matters for conceptual engineering; then, by comparatively assessing them and selecting the most conducive one with a view to making conceptual engineering an actionable (...) method, that is, a method that can be applied effectively and consistently to specific case studies. The outcome is that conceptual engineering should be all about concepts on pain of pragmatic inconsistencies otherwise. (shrink)

The present paper shows how one might model Everettian quantum mechanics using hyperfinitely many worlds. A hyperfinite model allows one to consider idealized measurements of observables with continuous-valued spectra where different outcomes are associated with possibly infinitesimal probabilities. One can also prove hyperfinite formulations of Everett’s limiting relative-frequency and randomness properties, theorems he considered central to his formulation of quantum mechanics. Finally, this model provides an intuitive framework in which to consider no-collapse formulations of quantum mechanics more generally.

This paper explores the important role of critical science, and in particular of post-colonial and decolonial theories, in understanding and shaping the ongoing advances in artificial intelligence. Artificial intelligence is viewed as amongst the technological advances that will reshape modern societies and their relations. While the design and deployment of systems that continually adapt holds the promise of far-reaching positive change, they simultaneously pose significant risks, especially to already vulnerable peoples. Values and power are central to this discussion. Decolonial theories (...) use historical hindsight to explain patterns of power that shape our intellectual, political, economic, and social world. By embedding a decolonial critical approach within its technical practice, AI communities can develop foresight and tactics that can better align research and technology development with established ethical principles, centring vulnerable peoples who continue to bear the brunt of negative impacts of innovation and scientific progress. We highlight problematic applications that are instances of coloniality, and using a decolonial lens, submit three tactics that can form a decolonial field of artificial intelligence: creating a critical technical practice of AI, seeking reverse tutelage and reverse pedagogies, and the renewal of affective and political communities. The years ahead will usher in a wave of new scientific breakthroughs and technologies driven by AI research, making it incumbent upon AI communities to strengthen the social contract through ethical foresight and the multiplicity of intellectual perspectives available to us, ultimately supporting future technologies that enable greater well-being, with the goal of beneficence and justice for all.

People increasingly form beliefs based on information gained from automatically filtered Internet ‎sources such as search engines. However, the workings of such sources are often opaque, preventing ‎subjects from knowing whether the information provided is biased or incomplete. Users’ reliance on ‎Internet technologies whose modes of operation are concealed from them raises serious concerns about ‎the justificatory status of the beliefs they end up forming. Yet it is unclear how to address these concerns ‎within standard theories of knowledge and justification. (...) To shed light on the problem, we introduce a ‎novel conceptual framework that clarifies the relations between justified belief, epistemic responsibility, ‎action, and the technological resources available to a subject. We argue that justified belief is subject to ‎certain epistemic responsibilities that accompany the subject’s particular decision-taking circumstances, ‎and that one typical responsibility is to ascertain, so far as one can, whether the information upon which ‎the judgment will rest is biased or incomplete. What this responsibility comprises is partly determined by ‎the inquiry-enabling technologies available to the subject. We argue that a subject’s beliefs that are ‎formed based on Internet-filtered information are less justified than they would be if she either knew how ‎filtering worked or relied on additional sources, and that the subject may have the epistemic ‎responsibility to take measures to enhance the justificatory status of such beliefs.‎.

In this paper, I investigate the foundations of Plotinus’ innovative theory that prime matter is unaffectable. I begin by showing that Plotinus’ main arguments for this thesis (in Ennead 3.6) all rely upon the controversial assumption that the properties prime matter underlies are not properties of prime matter itself. It is then argued that prime matter’s privation of sensible qualities has its conceptual basis in an idiosyncratic understanding of form-matter composition generally, and its primary doctrinal basis in Aristotle’s critical reports (...) on the Platonists’ substratum in Physics 1.9. While Plotinus finds Platonic authority for unaffectible matter in the Receptacle passage of the Timaeus, it is Aristotle’s testimony that provides the crucial impetus for reading that text in this way. On this basis, Plotinus develops a Platonist conception of form’s inherence in matter with distinctively non-Aristotelian features. (shrink)

The paper includes a series of letters exchanged between the author and the late Professor Feyerabend, concerning the best "method" for military intelligence, as a test case for the role of conceptual frameworks in philosophy of science. The letters deal with issues like: Is it possible to make an intelligence estimate without a conceptual framework? Does such a framework have any 'positive' role? If so, how should a conceptual framework in intelligence be built? What risks lurk within it? Is it (...) possible to indicate methods for intelligence estimates which are 'better' and more 'successful' than others? (shrink)

We study thorn forking and rosiness in the context of continuous logic. We prove that the Urysohn sphere is rosy (with respect to finitary imaginaries), providing the first example of an essentially continuous unstable theory with a nice notion of independence. In the process, we show that a real rosy theory which has weak elimination of finitary imaginaries is rosy with respect to finitary imaginaries, a fact which is new even for discrete first-order real rosy theories.

Mill defines utilitarianism as the combination of a “theory of life” and a moral claim: only pleasure and freedom from pain are desirable as ends, and the promotion of happiness is the sole goal of moral action. So defined, utilitarianism is open to ad hominem pessimistic objection: a “theory of life” which entails the impossibility of happiness fits poorly with a morality centered on its promotion. The first two challenges Mill confronts in Utilitarianism share this pessimistic structure. Interestingly, however, these (...) challenges paint inverted pictures of the best utilitarian life: one suggests this life is satisfying but ignoble, the other that it is noble but unsatisfying. I explain Mill's treatment of both challenges as genuinely pessimistic interpretations of utilitarianism's “theory of life.” Read through the lens of Mill's engagement with pessimism, these challenges point to distinctive conceptions of dignity and satisfaction that play a significant role in Mill's ethics.

While the evidential problem of evil has been enormously influential within the contemporary philosophical literature—William Rowe’s 1979 formulation in “The Problem of Evil and Some Varieties of Atheism” being the most seminal—no academic research has explored what cognitive mechanisms might underwrite the appearance of pointlessness in target examples of suffering. In this exploratory paper, we show that the perception of pointlessness in the target examples of suffering that underwrite Rowe’s seminal formulation of the problem of evil is contingent on the (...) absence of broader context. In other words, we show that when such suffering is presented alongside broader contextual information, the appearance of pointlessness, on average, significantly diminishes. In §1 we briefly elucidate Rowe’s formulation of the problem of evil and the thought experiment that motivates a key premise. In §2 and §3 respectively, we briefly explain our hypothesis regarding Rowe’s case and our methods for testing these hypotheses. In §4, we elucidate our results, and in §5 we explore some of the philosophical implications of our findings and gesture towards some areas for future research. Finally, in §6, we briefly connect our research to some of the established philosophical literature on suffering and narrative before concluding. (shrink)

Though one could not exhaustively and conclusively define all the attributes of an information/knowledge society, it seems Uganda has made commandable strides to such society. One of the prerequisites of such society is a corps of well-educated, trained and experienced information professionals to manage information and knowledge effectively in that society. Furthermore, the corps must perform professionally and ethically at all times. To fulfill this, an Information Code of Ethics is required. However, Uganda has as yet to establish an ICE (...) because of some reasons. These reasons are outlined in the paper. The ICE has two as-pects: theory and practice. These concepts are explained and related. The LA and the Chartered Institute of Library and Information Professions formerly the LA are studied as living examples. The provisions of these ICEs are briefly explained. In view of the past experience a process of establishing an IME for Uganda is considered. The paper concludes with an outline of the content of an IME for Uganda. (shrink)

Mechanism realists assert the existence of mechanisms as objective structures in the world, but their exact metaphysical commitments are unclear. We introduce Local Hierarchy Realism (LHR) as a substantive and plausible form of mechanism realism. The limits of LHR reveal a deep tension between two aspects of mechanists’ explanatory strategy. Functional decomposition identifies locally relevant entities and activities, while these same entities and activities are also embedded in a nested hierarchy of levels. In principle, a functional decomposition may identify entities (...) engaging in causal interactions that crosscut the hierarchical structure of composition relations, violating the mechanist’s injunction against interlevel causation. We argue that this possibility is realized in the example of ephaptic coupling, a subsidiary process of neural computation that crosscuts the hierarchy derived from synaptic transmission. These considerations undermine the plausibility of LHR as a general view, yet LHR has the advantages that (i) its metaphysical implications are precisely stateable; (ii) the structure it identifies is not reducible to mere aggregate causation; and (iii) it clearly satisfies intuitive and informal definitions of mechanism. We conclude by assessing the prospects for a form of mechanism realism weaker than LHR that nevertheless satisfies all three of these requirements. (shrink)

Despite the various perceptual-motor deficits documented in strabismus, there is a paucity of studies evaluating visual illusions in patients with strabismus. The aim of this study was to examine how the illusionary perception occurs in children/adolescents with strabismus with referral for surgery to correct ocular deviations. A controlled cross-sectional study was carried out in which 45 participants with strabismus and 62 healthy volunteers aged 10–15 years were evaluated. The behavioral response to three geometric illusions [Vertical-Horizontal illusion, Müller-Lyer illusion and Ponzo (...) illusion] and respective neutral stimuli regarding the estimation of image size and response time were measured using the Method of Adjustment. To analyze the influence of secondary factors: type of ocular deviation ; amount of eye deviation; presence of amblyopia and stereopsis, a one-way ANOVA was performed. Among the tested illusions, children with strabismus showed greater susceptibility and response time to Ponzo’s illusory images. Children with strabismus and preserved stereopsis, on the other hand, showed similar susceptibility and response time to control group patients to the Ponzo illusion. Patients with amblyopia showed overcorrection in the estimate of non-illusory Ponzo images. Children with horizontal ocular deviation associated with vertical deviation showed higher susceptibility to vertical adjustment images for the Müller-Lyer illusion. Individuals with strabismus tended to overcorrect the length of the straight-line segment adjusted for non-illusory images when testing non-illusory images in the Müller-Lyer test, as well as for the neutral images in the Vertical-Horizontal test. The findings indicated impairment in the perception of geometric illusions and neutral figures, especially for the Ponzo illusion test by children with strabismus. As the behavioral response to illusory images may indirectly reflect the visual and morphofunctional alterations present in these individuals, we suggest that the investigation of visual illusory perception can be used as a new research strategy in the field of investigating the visual function in strabismus.

Childbearing trans and nonbinary people are confronted with the heteronormative and cisgender frameworks that underpin “maternity” services. We explored the educational needs of 108 perinatal staff in the United Kingdom as related to the needs of trans and nonbinary service users. Participants were most confident in formulating care plans and least confident about the provision of colleagues’ perinatal care in this context. While the majority of participants were positive toward the trans and nonbinary communities, they considered that those communities remain (...) marginalized in perinatal services. Transphobic, anti-trans, and nonbinary attitudes were highlighted by our respondents. Our findings suggest that caregivers witnessed transphobia among colleagues and were apprehensive themselves about providing care to childbearing trans and nonbinary people. They reported a cisheteronormative model of care that lacked awareness of trans and nonbinary issues. The educational needs identified included information about the practicalities of childbearing as a trans or nonbinary person, how to use inclusive language effectively, and creating policies and processes for supporting childbearing trans and nonbinary people. These caregivers’ preferences included hearing from trans and nonbinary people and sharing best practices among themselves, with open discussions about how to be inclusive. (shrink)
