Pete Mandik, Slow Earth and the Slow-switching Slowdown Showdown | PhilPapers
Pete Mandik, Slow Earth and the Slow-switching Slowdown Showdown | PhilPapers
The present paper has three aims. The first and foremost aim is to introduce into philosophy of mind and related areas (philosophy of language, etc) a discussion of Slow Earth, an analogue to the classic Twin Earth scenario that features a difference from aboriginal Earth that hinges on time instead of the distribution of natural kinds. The second aim is to use Slow Earth to call into question the central lessons often alleged to flow from consideration of Twin Earth, lessons having to do with relations of minds to spatially definable boundaries of bodies such as skin or skull. The third aim is to suggest a puzzle for adherents of cognitive content externalism having to do with the metaphysical requirements on slow-switching, a hypothetical process whereby changes in the relations between subjects and their environments are followed by gradual changes in cognitive contents.

Philosophy TV on extended cognition: Kenneth Aizawa and Mark Rowlands
Is your appointment notebook simply a helpful tool, or is it partly constitutive of your memory process? According to the extended mind thesis, the mind and its processes can and do extend beyond the brain. Rowlands defends a version of that view. Aizawa doubts that extended cognition ever actually occurs, although he grants that it is conceptually possible. In this conversation, they examine their disagreement, and discuss the importance of establishing a “mark of the cognitive” to resolve the debate.

Abstract: The Slow-switching Slowdown Showdown

The Slow-switching Slowdown Showdown
Abstract:
The point of this paper is to raise a puzzle for cognitive content externalism. Central to the kind of externalism I wish to raise a puzzle for is a commitment to a thesis of slow switching: were Oscar stealthily transplanted on Twin Earth, replacing Twin Oscar, the thought contents expressed by Oscar’s “water” utterances would switch slowly from being thoughts of H2O to being thoughts of XYZ. The puzzle I want to raise centers on the question of how the externalist can account for the rate of slow switching. What’s especially puzzling about this question of rate is best brought out by considering certain natural extensions of externalism to contents concerning time and a modification of the Twin Earth thought experiment involving Slow Earth—a version of XYZ-covered Twin Earth where (just about) everything takes hundred times longer to occur on Slow Earth. It is a natural extension of externalism to time concepts to hold that Oscar and his counterpart on Slow Earth, Slow Oscar, express different thoughts by utterances employing temporal vocabulary such as “day,” “hour,” and “minute.” A further natural extension of externalism is to hold that if Oscar were stealthily transplanted to Slow Earth, not just his “water”-related concepts would slowly switch their contents, so would, e.g., his “hour”-related concepts. The question at the heart of my puzzle for the externalist is this: How long would slow switching take on Slow Earth? If everything is a hundred times slower on Slow Earth compared to non-slowed Twin Earth, then if slow switching takes a year on Twin Earth, it takes 100 years on Slow Earth (which is, of course, just one Slow Earth year). However, as I shall argue, it raises certain problems for externalists to hold that even slow switching is slowed down on Slow Earth. The core problem raised, I will argue, is that the externalist, in holding that slow switching slows on Slow Earth, is led to embrace a contradictory account of what the supervenience base is for wide-content temporal thoughts.

Justin Fisher: "Why Nothing Mental is Just in the Head"
Fisher, Justin. (forthcoming) “Why Nothing Mental is Just in the Head.” (forthcoming in Noûs) [link]
Abstract: Mental internalists hold that an individual’s mental features at a given time supervene upon what is in that individual’s head at that time. While many people reject mental internalism about content and justification, mental internalism is commonly accepted regarding such other mental features as rationality, emotion-types, propositional-attitude-types, moral character, and phenomenology. I construct a counter-example to mental internalism regarding all these features. My counter-example involves two creatures: a human and an alien from ‘Pulse World’. These creatures’ environments, behavioral dispositions and histories are such that it is intuitively clear that they are mentally quite different, even while they are, for a moment, exactly alike with respect to what’s in their heads. I offer positive reasons for thinking that the case I describe is indeed possible. I then consider ways in which mental internalists might attempt to account for this case, but conclude that the only plausible option is to reject mental internalism and to adopt a particular externalist alternative - a history-oriented version of teleo-functionalism.

the extended mind hypothesis
extended mind, the hypothesis that mental states themselves, as opposed to the factors determining their CONTENT, extend beyond the physical boundaries of an organism to include environmental phenomena. The extended-mind hypothesis may thus be characterized as a kind of vehicle EXTERNALISM and contrasted against content externalism (see VEHICLE; CONTENT/VEHICLE DISTINCTION). A key argument for the extended-mind hypothesis advanced by Andy Clark and David CHALMERS involves a THOUGHT EXPERIMENT concerning two characters, Inga and Otto (their names are evocative of “inner” and “outer”), who both make their way to a museum they’ve been to previously. Otto’s “memory” of where the museum is located is not encoded in his nervous system (he’s imagined to be an Alzheimer’s patient with difficulty doing such a thing) but is instead written down in his notebook. Inga, however, has no external record of the location of the museum but remembers the location in the usual way of what we would consider her MEMORY, perhaps by accessing INFORMATION stored in her nervous system. Clark and Chalmers urge the conclusion that the distributed system that includes Otto’s brain and notebook counts as no less a SUPERVENIENCE base for a (vehicle of) BELIEF than does Inga’s purely (or, at least, more) internal system.

Are there any non-question-begging arguments for externalism?
