Decades of psychological research have been aimed at modeling how people learn features and categories. The empirical validation of these theories is often based on artificial stimuli with simple representations. Recently, deep neural networks have reached or surpassed human accuracy on tasks such as identifying objects in natural images. These networks learn representations of real‐world stimuli that can potentially be leveraged to capture psychological representations. We find that state‐of‐the‐art object classification networks provide surprisingly accurate predictions of human similarity judgments for (...) natural images, but they fail to capture some of the structure represented by people. We show that a simple transformation that corrects these discrepancies can be obtained through convex optimization. We use the resulting representations to predict the difficulty of learning novel categories of natural images. Our results extend the scope of psychological experiments and computational modeling by enabling tractable use of large natural stimulus sets. (shrink)

Paul Benacerraf’s argument that mathematical realism is apparently incompatible with mathematical knowledge has been widely thought to also show that a priori knowledge in general is problematic. Although many philosophers have rejected Benacerraf’s argument because it assumes a causal theory of knowledge, some maintain that Benacerraf nevertheless put his finger on a genuine problem, even though he didn’t state the problem in its most challenging form. After diagnosing what went wrong with Benacerraf’s argument, I argue that a new, more challenging, (...) version of Benacerraf’s problem can be constructed. The new version—what I call the Defeater Version—of Benacerraf’s problem makes use of a no-defeater condition on knowledge and justification. I conclude by arguing that the best way to avoid the problem is to construct a theory of how a priori judgments reliably track the facts. I also suggest four different kinds of theories worth pursuing. (shrink)

One of the contentious philosophical issues surrounding the cognitive science of religion (CSR) is whether well-confirmed CSR theories would debunk religious beliefs. These debates have been contentious in part because of criticisms of epistemic principles used in debunking arguments. In this paper I use Ernest Sosa’s respected theory of knowledge as fully apt belief—which avoids objections that have been leveled against sensitivity and safety principles often used in debunking arguments—to construct a plausible debunking argument for religious belief on the assumption (...) that religious belief is formed simply through processes theorized by CSR. But, in fact, most believers also rely on arguments of various sorts, and their beliefs are not debunked. (shrink)

One of Laurence BonJour’s main arguments for the existence of the a priori is an argument that a priori justification is indispensable for making inferences from experience to conclusions that go beyond experience. This argument has recently come under heavy fire from Albert Casullo, who has dubbed BonJour’s argument, “The Generality Argument.” In this paper I (i) defend the Generality Argument against Casullo’s criticisms, and (ii) develop a new, more plausible, version of the Generality Argument in response to some other (...) objections of my own. Two of these objections stem out of BonJour’s failing to fully consider the importance of the distinction between being justified in believing that an inference is good and being justified in making an inference. The final version of the argument that I develop sees the Generality Argument as one part of a cumulative case argument for the existence of a priori justification, rather than as a stand-alone knock-down argument.

According to the most recent articulation of her view, Marilyn Adams’s reply to the problem of horrendous evils states that God offers compensation to those who experience horrendous evils. This compensation includes the good of the incarnation of God and the good of identification with God in virtue of suffering horrendous evils. Andrew Gleeson has raised a series of objections to Adams’s recent articulation. I argue that all of Gleeson’s arguments fail or fail to pose a distinct challenge. I then (...) present a different challenge: that her view provides insufficient compensation for horrendous evils. I conclude by suggesting a development of her view. (shrink)

As some artists discovered early in the century, there is a particular pleasure and stimulation to be derived from works of art created by cultures untouched by our own traditions of form. In part this is probably a delight in exoticism, in being away from home, and in part it possibly is our sentiment for cultures we look on as traditional, in a Jungian sense, or primitive in their unquestioning allegiance to simple cultural necessity. But more significantly, without indulging in (...) philosophical or anthropological speculation, we are forced, in looking at such objects as these elegantly designed boxes and bowls, to revise our visual thinking, our assumptions about unity and grace.Joshua C. Taylor, director of the National Collection of Fine Arts of the Smithsonian Institution, has written Learning to Look, William Page: The American Titian, and catalogues of exhibits of futurism and the works of Umberto Boccioni. Part 1 of this paper has been published in somewhat different form in Boxes and Bowls. (shrink)

Anselm’s argument in Cur Deus Homo commits him to the existence of collective sin and to Jesus’s offering recompense for the human race’s collective sin. By “collective sin” I mean sin of a collective entity—in this case, the human race. In the bulk of this paper I argue that one of Anselm’s defenses of a crucial assumption of his argument—what I call Anselm’s Principle—can succeed only on the assumption that Jesus offers recompense for the collective sin of the human race. (...) At the end of the paper’s final section I briefly present a second argument that another, quite separate, aspect of Anselm’s argument—regarding the conditions for blessed happiness—also implies that Jesus offers recompense for the collective sin of the human race.

I argue that ensouled animalism—the view that we are identical to animals that have immaterial souls as parts—has a pair of advantages over its two nearest rivals, materialistic animalism and pure dualism. Contra pure dualism, ensouled animalism can explain how physical predications can be literally true of us. Contra materialistic animalism, ensouled animalism can explain how animals can survive death. Furthermore, ensouled animalism has these advantages without creating any problems beyond those already faced by animalism and by belief in souls. (...) However, some animalists, including Eric Olson, think that animals cannot have immaterial parts. I present a sufficient condition for animal parthood that implies animals can have immaterial parts. Ensouled animalism is not only possible, but also doubly attractive. (shrink)

The last 15 years or so has seen the development of a fascinating new area of cognitive science: the cognitive science of religion (CSR). Scientists in this field aim to explain religious beliefs and various other religious human activities by appeal to basic cognitive structures that all humans possess. The CSR scientific theories raise an interesting philosophical question: do they somehow show that religious belief, more specifically belief in a god of some kind, is irrational? In this paper I investigate (...) this question and argue that CSR does not show that belief in god is irrational. (shrink)

An illustrated beginner's guide to the visual arts examines specific art works, studies expression and construction of art, and discusses creative and technical processes of art.

This Commentary offers a critique of an eco-relational approach in robot ethics, highlighting the importance of articulating an ecologically-sensitive ethical orientation that incorporates the entire more-than-human world, including technological entities like forms of artificial intelligence. While the eco-relational approach enhances our understanding of the complex way in which morally significant properties operate on a phenomenological level, it is not without its flaws. In particular, this perspective focuses on ethical concepts when it needs to be rooted in ethical systems, misrepresents the (...) extant literature on relational approaches to moral status, and is insufficiently ecological in a way that would bring machines into the moral universe by way of their location in and importance to the larger environment. At a time when the legal status of robots is being decided before moral questions are settled, it remains important to get the contours of relevant debates right so that the robot ethics discourse brings us closer to developing practical solutions for ethical dilemmas emerging in our increasingly technological age.

Ralph Cudworth, Doctor of Divinity, Master of Christ’s College at Cambridge, and philosophical chieftain of the Cambridge Platonists, published The True Intellectual System of the Universe in 1678 to disprove “the fatal necessity of all actions and events.” This disproof would destroy the various atheisms founded upon such “fatal necessity”; it would also correct those Christians who mistakenly honoured God by subjecting men to a divinely administered fate. Cudworth, with a constant eye on Hobbes, whom he did not name, struck (...) at atheism by establishing a “true intellectual system” and by arguing away its principle of fate. His design swelled as he worked to meet the various versions of “fatal necessity” with the various atheisms founded upon them, to establish the true doctrine, and to accommodate his own copious learning, and it swelled too much for the published work to be more than a first instalment of his whole design.

A young boy found one of Beck's best stereoscopes, but he did not understand its use. When he looked through the two eye-pieces at the two adjacent duplicates of each picture on each card he got a single flat picture, and he expected nothing more. Then the moment of revelation came. As he fumbled the focus onto a flat picture of Hamlet, the grave-diggers and Hamlet himself bulged out, the skull on Hamlet's palm looked like a museum piece, and the (...) grave yawned like a real pit. The stereoscopic world of the Beck instrument had been suddenly established in the boy's experience. (shrink)

When a rainbow spans the sky the eye may rest with simple rapture on the arch of colours, or the mind may interpret it as an interplay between raindrops and light. This perceptibly separates the aesthetic relish of the colours from the scientific understanding of the bow. Archbishop Temple distinguished the restfulness of art from the restlessness of science. This applies to the wider aesthetic which includes natural products, such as snow-scenes or daffodils or rainbows, with the pictures, statues, buildings, (...) poems, and other products of man-made art. The rainbow clearly separates the understanding sought by science from the immediate contemplative aesthetic satisfaction with the colours. (shrink)

Ultrasociality, as expressed in agricultural, monetary, and fossil fuel economies, has spurred exponential growth in population and in resource use that now threaten civilization. These threats take the form of prisoner's dilemmas. Avoiding collapse requires more cooperative economic organization that must be informed by knowledge of human behavior and cultural evolution. The evolution of a cooperative information economy is one possibility.
