Central to contemporary cognitive science is the notion that mental processes involve computations defined over internal representations. This view stands in sharp contrast to the to visual perception and cognition, whose most prominent proponent has been J.J. Gibson. In the direct theory, perception does not involve computations of any sort; it is the result of the direct pickup of available information. The publication of Gibson's recent book (Gibson 1979) offers an opportunity to examine his approach, and, more generally, to contrast (...) the theory of direct perception with the computational/representational view. In the first part of the present article (Sections 2direct perceptioncase study”: the problem of perceiving the three-dimensional shape of moving objects is examined. This problem, which has been extensively studied within the immediate perception framework, serves to illustrate some of the inherent shortcomings of that approach. Finally, in Section 5, an attempt is made to place the theory of direct perception in perspective by embedding it in a more comprehensive framework. (shrink)

Shanahan’s eloquently argued version of the global workspace theory fits well into the emerging understanding of consciousness as a computational phenomenon. His disinclination toward metaphysics notwithstanding, Shanahan’s book can also be seen as supportive of a particular metaphysical stance on consciousness — the computational identity theory.

The moral standing of involuntary sterilization has long been subject to debate but has only recently been looked upon with disfavor. When sterilization of a mentally handicapped minor is entertained, issues of eugenics, medical ethics, and legal precedent specially arise. Ethics consultants and ethics committees have been asked to consider such cases.

Photographers John Shimon and Julie Lindemann use antique cameras, modern lens technology, artificial light, and contemporary pop culture to create portraits of the people in their native state amidst backyards, living rooms, parking lots, and the landscape of Wisconsin. These recent photographs are juxtaposed with portraits from the Milwaukee Art Museum’s permanent collections, including daguerreotype portraits, ambrotypes, and tintypes of anonymous people taken by nineteenth-century photographers, as well with photographs by such well-known artists as Alfred Stieglitz, Sally Mann, Larry (...) Clark, Walker Evans, Nan Goldin, Eugene von Beuenchenhein, and Francis Ford. The pairings of new and old illustrate the legacy of portraiture and the significance of “posing” before the lens, and each image is enriched by its proximity to another, unmasking sitter, photographer, and viewer. Unmasked & Anonymous: Shimon & Lindemann Consider Portraiture includes more than sixty color and black-and-white photographs plus essays by Shimon, Lindemann, and Milwaukee Art Museum curator Lisa Hostetler.

This essay begins with the story of Vincent Lloyd who recounts a disturbing experience he had while teaching a course to a group of students of color. What does pedagogical uptake under conditions of systemic oppression require of educators? In the first section, I explore philosopher Nancy Potter’s (Nancy Potter. “Giving Uptake”. Social Theory and Practice 26/3 (2000) 479–508; Nancy Potter. The Virtue of Defiance and Psychiatric Engagement (Oxford: Oxford University Press, 2016)) work on uptake, whose focus on the mental (...) health field is important because she acknowledges power imbalances. Nevertheless, her understanding of uptake may be insufficient for considering such classroom cases that introduced this essay. The second section shifts the focus of uptake from a psychological approach to a more epistemic understanding of uptake that underscores credibility and intelligibility. Uptake as credibility and intelligibility reveals the everyday patterns of uptake failure that marginalized knowers experience in the socio-epistemic world, described in section three. A recent turn in the scholarship of epistemic injustice towards epistemic agency and resistance is taken up in the subsequent section and applied to the conceptualization of uptake. In the concluding section, I begin to explore how these insights contribute to a notion of pedagogical uptake under conditions of systemic oppression. (shrink)

Intelligent systems are faced with the problem of securing a principled (ideally, veridical) relationship between the world and its internal representation. I propose a unified approach to visual representation, addressing both the needs of superordinate and basic-level categorization and of identification of specific instances of familiar categories. According to the proposed theory, a shape is represented by its similarity to a number of reference shapes, measured in a high-dimensional space of elementary features. This amounts to embedding the stimulus in a (...) low-dimensional proximal shape space. That space turns out to support representation of distal shape similarities which is veridical in the sense of Shepard's (1968) notion of second-order isomorphism (i.e., correspondence between distal and proximal similarities among shapes, rather than between distal shapes and their proximal representations). Furthermore, a general expression for similarity between two stimuli, based on comparisons to reference shapes, can be used to derive models of perceived similarity ranging from continuous, symmetric, and hierarchical, as in the multidimensional scaling models (Shepard, 1980), to discrete and non-hierarchical, as in the general contrast models (Tversky, 1977; Shepard and Arabie, 1979).

Short essays that touch many topics-anxiety, consciousness, death, happiness, morality, stupidity, & truth-that make the case for realism & help set expectations with regard to the human condition.

The only viable formulation of perception, thinking, and action under uncertainty is statistical inference, and the normative way of statistical inference is Bayesian. No wonder, then, that even seemingly non-Bayesian computational frameworks in cognitive science ultimately draw their justification from Bayesian considerations, as enlightened theorists know fully well.

A well-known objection to prioritarianism, famously levelled by Mike Otsuka and Alex Voorhoeve, is that it wrongly ignores the unity of the individual in treating intra-personal cases like inter-personal cases. In this paper we accept that there should be a moral shift between these cases, but argue that this is because autonomy is a relevant consideration in intra-personal but not inter-personal cases, and one to which pluralist prioritarians ought to attend. To avoid this response, Otsuka and Voorhoeve must assume we (...) know nothing about the subjective information of the person being chosen for. But we show that this commits them to two controversial assumptions: that welfare consists in an objective list of goods, and – if one accepts an unorthodox but plausible account of the relationship between risk aversion and rationality – that there is only a narrow range of rational risk aversions. Only prioritarians who accept both these assumptions are on the hook of Otsuka and Voorhoeve’s objection; for all others, the examples have insufficient information, and so lose their sting.

The strangeness of modern physics has sparked several popular books--such as The Tao of Physics--that explore its affinity with Eastern mysticism. But the founders of quantum mechanics were educated in the classical traditions of Western civilization and Western philosophy. In Nature Loves to Hide, physicist Shimon Malin takes readers on a fascinating tour of quantum theory--one that turns to Western philosophical thought to clarify this strange yet inescapable explanation of reality. Malin translates quantum mechanics into plain English, explaining its (...) origins and workings against the backdrop of the famous debate between Niels Bohr and the skeptical Albert Einstein. Then he moves on to build a philosophical framework that can account for the quantum nature of reality. He shows, for instance, how Platonic and Neoplatonic thought resonates with quantum theory. He draws out the linkage between the concepts of Neoplatonism and the more recent process philosophy of Alfred North Whitehead. The universe, Whitehead wrote, is an organic whole, composed not of lifeless objects, but "elementary experiences." Beginning with Whitehead's insight, Malin shows how this concept of "throbs of experience" expresses quantum reality, with its subatomic uncertainties, its constituents that are waves and also particles, its emphasis on acts of measurement. Once any educated person could explain the universe as a vast Newtonian web of cause and effect, but since quantum theory, reality again appears to be richer and more mysterious than we had thought. Writing with broad humanistic insight and deep knowledge of science, and using delightful conversations with fictional astronauts Peter and Julie to explain more difficult concepts, Shimon Malin offers a profound new understanding of the nature of reality--one that shows a deep continuity with aspects of our Western philosophical tradition going back 2500 years, and that feels more deeply satisfying, and truer, than the clockwork universe of Newton.

Mohandas K. Gandhi (1869–1948)’s relationship with the Jews is explored in this article. The history of this relationship can be divided into two different periods. The first begins during his formative years in South Africa from 1893 to 1914, and the second, during his political activism in India thereafter. The article points out that Gandhi’s close Jewish associates in South Africa, although coming primarily from a Theosophist background, considered their support of Gandhi and his struggle to represent their core Jewish (...) values. Still, Gandhi’s close Jewish supporters did not successfully influence Gandhi regarding Zionism. In retrospect, Gandhi’s objection to Zionism enormously impacted the Indian Congress Party’s position regarding Palestine. The article notes that although Gandhi opposed political Zionism, he supported Zionism as a spiritual movement that could be best realized “within.” Somewhat surprising and little-known fact was a desire on Gandhi’s part to mediate between the Arabs and the Jews in direct talks. Gandhi hoped the Zionist leaders would respond positively to his offer to mediate so that he could advance his teachings of nonviolence while also claiming to represent the Indian Muslims. The article discusses Gandhi’s call to German and European Jews to resist the Nazi regime by adopting Satyagraha, the consequent rift with Jewry that followed, and his silence after the Holocaust. Finally, the article also briefly explores B. R. Ambedkar (1891–1956)’s views on the Jews and the Indian pariahs. (shrink)

We prove that the strong polarized relation $\left( {\mu _\mu ^ + } \right) \to \left( {\mu _\mu ^ + } \right)_2^{1.1}$ is consistent with ZFC, for a singular ì which is a limit of measurable cardinals.

This article analyses the biochemical object of tnf inhibitors from the perspective of living with an autoimmune disease. The author tries to tease out how the concept of immune inhibition is used in tandem with the biochemical object of tnf inhibitors to dominate in defining and narrating what health and disease, normal and pathological, cure and healing can mean in the context of autoimmune bodies. Specifically, and within the ‘pathological’ framework of autoimmune diseases, the pharmacological treatment of tnf inhibition is (...) designed to suppress the ‘overly’ active immune system, thus acting as a negative or suppressing biochemical agent aimed at putting the ‘malfunctioning’ immune system back in balance. As can be seen in the current conjuncture, tnf inhibitors officially —and governmentally— place those taking them in a risk group, as they 'lower' their overall bodily immunity and make them more vulnerable to infectious diseases, while stabilizing their patho-logical, ‘over’-immune uninhibited condition. Part personal narrative of being diagnosed with an autoimmune condition, part speculative autoimmune theory inspired by such a diagnosis, the article ultimately calls for a different form of embodiment that is neither negative nor affirmative, and yet is resistant even to itself.

The recent essay by Schuklenk and Smalling opposing respect for physicians’ conscientious objections to providing patients with medical services that are legally permitted in liberal democracies is based on several erroneous assumptions. Acting in this manner would have serious harmful effects on the ethos of medicine and of bioethics. A much more nuanced and balanced position is critical in order to respect physicians’ conscience with minimal damage to patients’ rights.

We address the question of consistency strength of certain filters and ultrafilters which fail to satisfy the Galvin property. We answer questions [Benhamou and Gitik, Ann. Pure Appl. Logic 173 (2022) 103107; Questions 7.8, 7.9], [Benhamou et al., J. Lond. Math. Soc. 108(1) (2023) 190–237; Question 5] and improve theorem [Benhamou et al., J. Lond. Math. Soc. 108(1) (2023) 190–237; Theorem 2.3].

Suppose $D$ is an ultrafilter on $\kappa$ and $\lambda^\kappa = \lambda$. We prove that if ${\bf B}_i$ is a Boolean algebra for every $i.

We characterize the situation of having at least $^{+}$-many normal ultrafilters on a measurable cardinal $\kappa$. We also show that if $\kappa$ is a compact cardinal, then $\kappa$ carries $^{+}$-many $\kappa$-complete ultrafilters, each of which extends the club filter on $\kappa$.

We show that the character spectrum Spχ may include any prescribed set of regular cardinals between λ and 2λ.
