• Merrie Bergmann　　An Introduction to Many-Valued and Fuzzy Logic: Semantics, Algebras, and Derivation Systems, Cambridge University Press, 2008

This volume is an accessible introduction to the subject of many-valued and fuzzy logic suitable for use in relevant advanced undergraduate and graduate courses. The text opens with a discussion of the philosophical issues that give rise to fuzzy logic – problems arising from vague language – and returns to those issues as logical systems are presented. For historical and pedagogical reasons, three-valued logical systems are presented as useful intermediate systems for studying the principles and theory behind fuzzy logic.

これは何だか勉強になりそうなので注文しておく。Deviant または alternative logic の入門書が出れば、基本的にはいつも購入する方向でいますので…。
