Logical Consequence Philosophy of Logic and Language — HT 2017-18
Lecture 7: Logical Consequence Philosophy of Logic and Language — HT 2017-18 Jonny McIntosh [email protected] Works by Tarski The main text by Tarski this week is ’On the Concept of Logical Consequence’; ’Truth and Proof’ is a very accessible presentation, written much later: Alfred Tarski (1936) ’On the Concept of Logical Consequence’ in his (1983) Logic, Se- mantics, Metamathematics, 2nd revised edition (Hackett). — (1969) ‘Truth and Proof’ in Scientific American 220, pp. 63-77. Secondary Reading Starred items (*) are more introductory, and good places to start. Coffa (1991) traces the historical roots of Tarski’s account of logical consequence (among other things). Quine attacks the analytic/synthetic distinction in his (1951) and defends a version of the sub- stitutional conception in his (1986). For more discussion of formality, see in particular Etchemendy (1983) and Macfarlane (2000). Etchemendy (2008) is the best place to start for his objections, though see his (1990/1999) for extended discussion. For responses, see McGee (1992), Sher (1996), Hanson (1997), Gomez-Torrente´ (1999), Soames (1999), and Paseau (2013). *JC Beall and Greg Restall (2005/2013) ’Logical Consequence’ in E. Zalta, ed.

Chinese Public AI R&D Spending: Provisional Findings
DECEMBER 2019 Chinese Public AI R&D Spending: Provisional Findings CSET Issue Brief AUTHORS Ashwin Acharya Zachary Arnold Executive Summary China aims to become “the world’s primary AI innovation center” by 2030.1 Toward that end, the Chinese government is spending heavily on AI research and development (R&D). This memo provides a provisional, open-source estimate of China’s spending. We assess with low to moderate confidence that China’s public investment in AI R&D was on the order of a few billion dollars in 2018. With higher confidence, we assess that China’s government is not investing tens of billions of dollars annually in AI R&D, as some have suggested.2 Significant data gaps prevent us from producing a more precise estimate of China’s spending at this time, especially with respect to defense R&D. However, our rough estimate and the underlying analysis do allow us to rule out higher estimates with moderate to high confidence. Additional findings include: • China’s government probably isn’t dramatically outspending the U.S. government on AI R&D. While we did not analyze U.S. AI R&D spending in any depth for this paper, our results indicate that China’s spending in 2018 was on the same order of magnitude as U.S. planned spending for FY 2020, as documented elsewhere.3 • Chinese public AI R&D spending probably tilts heavily toward applied research and experimental development, not basic research. This is consistent with China’s overall public R&D spending.4 • China’s government may be investing a few billion dollars a year (at most) in private-sector AI activity through guidance funds— essentially, state-backed venture capital funds. -

The Liar: an Essay in Truth and Circularity, by Jon Barwise and John Etchemendy, Oxford University Press, New York and Oxford, 1987, Xii + 185 Pp., $19.95
216 BOOK REVIEWS BULLETIN (New Series) OF THE AMERICAN MATHEMATICAL SOCIETY Volume 20, Number 2, April 1989 ©1989 American Mathematical Society 0273-0979/89 $1.00 + $.25 per page The Liar: An essay in truth and circularity, by Jon Barwise and John Etchemendy, Oxford University Press, New York and Oxford, 1987, xii + 185 pp., $19.95. ISBN 0-19-505072-x Consider the classic Liar sentence: "This sentence is false." It claims that it is false. So if we assume that a sentence is true if and only if what it claims is the case, then the Liar is true if and only if it is false. People have thought about this paradox for centuries. Despite this, there is no single standard "solution." An attempted resolution of the paradox would tell us which of our intuitions are sound and which need further clarification. It would point out where and why our naive reasoning leads us to a contradiction. Modern logic applies mathematical methods to the modeling and study of truth, proof, computation, and infinity. The paradoxes of semantics and set theory were important in the development of the field. The reason for working on the paradoxes of any field is not only to secure a foundation. The deeper reason is that by introducing, discarding, and clarifying the concepts that lead to paradox we are lead to the central ideas and questions of the field. We see from The Liar that the paradoxes are still a source of inspiration in logic. The book is a new, exciting contribution to the study of truth. -

Facebook's Emotional Contagion Experiment As a Challenge

The massive-scale experiment manipulated the News Feeds of a large amount of Facebook users and was successful in proving that emotional contagion happens also in online environments. However, the experiment caused ethical concerns within and outside academia mainly for two intertwined reasons, the first revolving around the idea of research as manipulation, and the second focusing on the problematic definition of informed consent. The article concurs with recent research that the era of social media and big data research are posing a significant challenge to research ethics, the practice and views of which are grounded in the pre social media era, and reflect the classical ethical stances of utilitarianism and deontology.
