Oxford UPのCatalogueを見てたらここ半年ぐらいにPhilosophy of LogicやPhilosophy of Mathematicsの面白そうな本がいくつも出ることがわかる。中でも次の二つがとても気にかかる。
- Christopher Hughes Kripke: Names, Necessity, and Identity (Paperback Edition)
hardがついこの前出ていましたがpaperなら買おうかなと思っていた1冊。こちらは買おう。Kripkeの考えを全体的に俯瞰する入門書。あまり全体をまとめたものはないらしいとのことでよいかも。
- Jonathan L. Kvanvig The Knowability Paradox
本日一番最初に掲げた入手文献はこの本の著者によるもの。Descriptionの一部はこう。
- The fullest account of the knowability paradox to date
- Proposes both a a new understanding of the paradox and an original solution to it
- Important for epistemologists as well as for those engaged with truth and logic
The paradox of knowability, derived from a proof by Frederic Fitch in 1963, is one of the deepest paradoxes concerning the nature of truth. Jonathan Kvanvig argues that the depth of the paradox has not been adequately appreciated. It has long been known that the paradox threatens antirealist conceptions of truth according to which truth is epistemic. If truth is epistemic, what better way to express that idea than to maintain that all truths are knowable? In the face of the paradox, however, such a characterization threatens to undermine antirealism. If Fitch's proof is valid, then one can be an antirealist of this sort only by endorsing the conclusion of the proof that all truths are known.
…
This book thus provides a thorough investigation of the literature on the paradox, and also proposes a solution to the deeper of the two problems raised by Fitch's proof. It provides a complete picture of the paradoxicality that results from Fitch's proof, and presents a solution to the paradox that claims to address both problems raised by the original proof.
この本は買おうかどうか迷う。Knowability Paradoxにはすごく興味があるが、そんなに専門的に首を突っ込もうとしているわけではないので、自分にしてはこの本はちょっと専門的過ぎるかな？ 現物見てから判断しよう。そして初めの導入部の入門的箇所だけ、大学に入ればcopyしてもいいかも。
