An Ultra‐Realist Theory of Perception

In this paper I argue for a theory of perception distinct both from classical sense‐datum theories and from intentionalist theories, that is theories according to which one perceives external objects by dint of a relation with a propositional content. The alternative I propose completely rejects any representational element in perception. When one sees that an object has a property, the situation or state of affairs of its having that property is one's perception, so that the object and property are literally part of one's mind. The most obvious objection to this view is that it embodies a rampant form of idealism. It is argued to the contrary, via consideration of the metaphysics of situations, that the theory is entirely consistent with a robustly realist view of the world.     

From Conceptual Analysis to Serious Metaphysics

Abstract

Habermas’s recent work in epistemology has been marked by a decisive rejection of his earlier epistemic conception of truth in which he understood truth as ‘what may be accepted as rational under ideal conditions’. Arguing that no ‘idealization of justificatory conditions’ can do justice to both human fallibility and the unconditional nature of truth, he has attempted to develop a realistic conception of truth that severs any conceptual link between truth and justification while respecting the epistemic relevance of justification for ascertaining the truth. But realizing this second goal has proved elusive for Habermas because he veers too close to a form of metaphysical realism in his epistemology. By contrast, Hilary Putnam’s recent turn to what he calls ‘natural realism’ is more successful in articulating a form of realism that, in taking its leave of an epistemic conception of truth, still manages to keep its distance from metaphysical realism.     

The Limits of Photography

Abstract

This paper is about what counts as a photograph and what does not. One way in which this question arises stems from new technologies that keep changing our way of producing photographs, such as digital photography, which not only has now widely replaced traditional film photography but also challenges the very limits of what we count as a photograph. I shall discuss below at some length different aspects of digital photography, but also want to focus here on a new striking type of photographic camera, announced in early 2012 by Lytro, Inc., namely, the so-called ‘Light Field Camera’, which is said to represent a revolution in the photographic world. Indeed, unlike in the case of any previously available cameras, the photographs produced by a Light Field Camera can be re-focused after the photograph has been taken, which harbours many interesting consequences with regard to the resulting image and the way we interact with it. But of course, the initial question also arises in the case of traditional film photography as well as ‘traditional’ digital photography. The question amounts to asking about what the essential features of photographs are – in short, what their nature is.     

Ostrich Nominalism and Peacock Realism: A Hegelian Critique of Quine

Abstract

My aim in this paper is to offer a Hegelian critique of Quine’s predicate nominalism. I argue that at the core of Hegel’s idealism is not a supernaturalist spirit monism, but a realism about universals, and that while this may contrast to the nominalist naturalism of Quine, Hegel’s position can still be defended over that nominalism in naturalistic terms. I focus on the contrast between Hegel’s and Quine’s respective views on universals, which Quine takes to be definitive of philosophical naturalism. I argue that there is no good reason to think Quine is right to make this nominalism definitive of naturalism in this way – where in fact Hegel (along with Peirce) offers a reasonably compelling case that science itself requires some commitment to realism about universals, kinds, etc. Furthermore, even if Hegel is wrong about that, at least his case for realism is still a naturalistic one, as it is based on his views on concrete universality, which is an innovative form of in rebus realism about universals.     

In Defense of Anti‐Archimedean Moral Realism: A Response to Recent Critics

Ronald Dworkin famously argued that many putatively nonmoral metaethical theories can only be understood as being internal to the moral domain. If correct, this position, referred to as anti‐archimedeanism, has profound implications for the methodology of metaethics. This is particularly true for skeptical metaethical theories. This article defends a version of anti‐archimedeanism that is true to the spirit rather than the letter of Dworkin's original thesis from several recent objections. First, it addresses Kenneth Ehrenberg's recent attempt to demonstrate how certain metaethical theories can be understood in a morally neutral manner. It then discusses Charles Pigden's claim that Dworkin begs the question against error theorists and nihilists by assuming a conceptual space that error theorists and nihilists would reject. It concludes that the anti‐archimedean methodology originally proposed by Dworkin is defensible, and can be used to support a robust form of moral realism.     

A Mereological Challenge to Endurantism

In this paper, we argue that time travel is problematic for the endurantist. For it appears to be possible, given time travel, to construct a wall out of a single time travelling brick. This commits the endurantist to one of the following: (a) the wall is composed of the time travelling brick many times over; (b) the wall does not in fact exist at all; (c) the wall is identical to the brick. We argue that each of these options is unsatisfactory.     

Critical Realism—A Sustainable Bridge Between Science and Religion?

Since Barbour's introduction of the term in 1966, “critical realism” bridges the gulf between science and religion. Yet, like the Golden Gate Bridge, this bridge must be supported by pillars to carry its weight. These pillars are the social and the human sciences, which are still designed too small within critical realism to make a really sustainable construct. Critical realism should be modified to “constructive-critical realism” to allow for more weight of these disciplines in the dialog, which actually should become a trialog.     

Natural character: psychological realism for the downwardly mobile

Nancey Murphy recently offered a proposal for altruistic self-renunciation as the core theory of a Christian research program in psychology. Her argument intersects with recent concerns in moral psychology that theory should be constrained by the lives of ordinary people, an idea known as psychological realism. This article considers limitations for altruistic self-renunciation through research with L’Arche assistants for the developmentally disabled. Incipient, “natural” character is evident through the ambivalence of these everyday altruists, creating a difficult methodological challenge for the psychological realist. Consequently, a novel approach for the mathematical analysis of subject narrative is explored with the use of a powerful computational linguistics program.     

Scientific Realism and the Meanings of Theoretical Terms

In contemporary philosophy of science, there are many interesting arguments for and against scientific realism with regard to the meaningfulness and truthfulness of theoretical statements. Some anti-realists hold that since many important concepts in scientific theories have no specific referents, the relevant theoretical statements are therefore either false or meaningless. In this essay, I join the debates concerning the plausibility of scientific realism by focusing on two intertwined issues： first, that of how we can we explicate the meaningfulness of theoretical statements, especially statements pertaining to unobservable objects, and second, that of the meaningfulness of theoretical statements for our acceptance of scientific realism.
