If the contents of our thoughts are partly determined by facts outside our heads, can we still know those contents directly, without investigating our environment? What if we were surreptitiously switched to Twin-Earth? Would we know the contents of our thoughts under these unusual circumstances? By looking carefully at what determines the content of a second-order thought, a candidate for self-knowledge, the paper argues that we can know the contents of our thoughts directly, even after being switched. Learning about the (...) switch, however, does raise some interesting difficulties. (shrink)

Sven Bernecker presents an analysis of the concept of propositional (or factual) memory, and examines a number of metaphysical and epistemological issues crucial to the understanding of memory. -/- Bernecker argues that memory, unlike knowledge, implies neither belief nor justification. There are instances where memory, though hitting the mark of truth, succeeds in an epistemically defective way. This book shows that, contrary to received wisdom in epistemology, memory not only preserves epistemic features generated by other epistemic sources but also functions (...) as a source of justification and knowledge. According to the causal theory of memory argued for in this book, the dependence of memory states on past representations supports counterfactuals of the form: if the subject hadn't represented a given proposition in the past he wouldn't represent it in the present. The book argues for a version of content externalism whereupon the individuation of memory contents depends on relations the subject bears to his past physical or social environment. Moreover, Bernecker shows that memory doesn't require identity, but only similarity, of past and present attitudes and contents. The notion of content similarity is explicated in terms of the entailment relation. (shrink)

Reflection on testimony provides novel arguments for anti-individualism. What is anti-individualism? Sanford Goldberg's book defends three main claims under this heading: first, facts about the contents of beliefs do not supervene on individualistic facts about the believers ; second, an individual's epistemic entitlement to accept a piece of testimony depends on facts about her peers ; third, processes by which some humans acquire knowledge from testimony includes activities performed for them by others. Each of these three claims is argued for (...) separately from premises about the ways in which humans, adult and child, succeed in gaining knowledge by testimony. The three arguments provide the structure for Anti-Individualism.Goldberg's argument for the first claim – that the contents of beliefs do not supervene on individualistic facts about the believers – begins from uncontroversial facts about testimony. Gaining knowledge by testimony depends on knowing the meanings of some utterances, and it is possible to know the meaning of a person's utterance while knowing little that would distinguish this person from anyone else. The best explanation of how this is possible involves postulating linguistic norms which entail facts about the linguistic meanings of utterances. Now in some cases of testimony, a hearer acquires a belief whose content is the linguistic meaning of a speaker's utterance, where the linguistic meaning of this utterance is determined by linguistic norms. But linguistic norms might have been different from what they are even while the person's and her audience's non-relational properties remained unaltered. And in such a case, the hearer would have acquired a belief with a different content. Therefore, ‘Psychological facts such as believing that p do not supervene on the individualistic facts regarding the subject’ …. (shrink)

Sanford C. Goldberg argues that a proper account of the communication of knowledge through speech has anti-individualistic implications for both epistemology and the philosophy of mind and language. In Part I he offers a novel argument for anti-individualism about mind and language, the view that the contents of one's thoughts and the meanings of one's words depend for their individuation on one's social and natural environment. In Part II he discusses the epistemic dimension of knowledge communication, arguing that the epistemic (...) characteristics of communication-based beliefs depend on features of the cognitive and linguistic acts of the subject's social peers. In acknowledging an ineliminable social dimension to mind, language, and the epistemic categories of knowledge, justification, and rationality, his book develops fundamental links between externalism in the philosophy of mind and language, on the one hand, and externalism is epistemology, on the other.

Most explorations of the epistemic implications of Semantic Anti- Individualism (SAI) focus on issues of self-knowledge (first-person au- thority) and/or external-world skepticism. Less explored has been SAIs implications forthe epistemology of reasoning. In this paperI argue that SAI has some nontrivial implications on this score. I bring these out by reflecting on a problem first raised by Boghossian (1992). Whereas Boghos- sians main interest was in establishing the incompatibility of SAI and the a priority of logical abilities (Boghossian 1992: 22), (...) I argue that Boghossians argument is better interpreted as pointing to SAIs implications for the na- ture of discursive justification. (shrink)
