Concept-individuating reference rules offer a well-known route for the explanation of immunity to error through misidentification in judgments involving first person or de se thought. However, the ‘outright’ version of this account—one that sanctions a one-to-one correspondence between the reference-fixing rule and immunity—cannot do justice to the unassailable ground-relativity of the target phenomenon. In this paper, I outline a version of the reference-rule account that circumvents this problem. I state a reference rule for the de se concept that makes space (...) for different non-reference-fixing ways of thinking or perspectives, yielding different grounds for judgment. The proposal and its ramifications, I argue, shed light on the variety of ways in which this kind of immunity has been proved to be present—and indeed absent—in de se thought. (shrink)

Subjects suffering from extreme peripheral deafferentation can recruit vision to perform a significant range of basic physical actions with limbs they can’t proprioceptively feel. Self-ascriptions of deafferented action – just as deafferented action itself – fundamentally depend, therefore, on visual information of limb position and movement. But what’s the significance of this result for the concept of self patently at work in these self-ascriptions? In this paper, I argue that these cases show that bodily awareness grounding employment of the self-concept (...) in self-ascriptions of action can be fundamentally third-personal and concern a body that is not presented as one’s own, but as an object among others.

David Chalmers argues that virtual objects exist in the form of data structures that have causal powers. I argue that there is a large class of virtual objects that are social objects and that do not depend upon data structures for their existence. I also argue that data structures are themselves fundamentally social objects. Thus, virtual objects are fundamentally social objects.

In this article I explore some implications of the correspondence that went on between Ludwig Wittgenstein and the logician and mathematician Gottlob Frege. Part of this exchange was focused on the envisaged publication of Wittgenstein’s Tractatus Logico-Philosophicus, and on the philosophical or literary character of that work. The problem discussed concerned the question of whether the Tractatus should be seen not as a scientific but as an artistic achievement. My first goal is to present what, given Frege’s writings, his phrase (...) “an artistic rather than a scientific achievement” could be understood to mean in terms of the Tractatus itself. Secondly, I seek to determine the extent to which traces of Frege’s understanding of such terms as “mock thoughts,” “fiction,” “elucidation,” “paintings” and “colouring” are to be found in the language of the Tractatus. This should then make it possible to show how Wittgenstein’s work, viewed from a Fregean perspective, can be seen as furnishing a logic and semantics not only for the languages of logic and natural science, but also for something that is “an artistic rather than a scientific achievement”, while also indicating that the content of the Tractatus as a whole could not have been captured independently of the unified form Wittgenstein himself gave it.
