but they are always thought provoking. In the reviewer’s opinion, the most glaring omission in the choice of topics in the text is the absence of any material on computability theory and incompleteness theorems. Of course there is only so much one can accomplish during a mere semester, and there is always the option of reaching for supplementary materials and texts, but I hope that the author would consider enriching the future editions of this text with a treatment of these two important topics. I wish to conclude this review with a brief discussion of Farsi logic textbooks in order to provide a background for thework reviewedhere. The firstmodern logic textbook inFarsiwas published in Iran more than half a century ago in 1955. It was authored by G. H. Mosaheb, a gifted and admirably tireless mathematician, educator, and man of letters. Thanks to the industry of Alonzo Church, the book was reviewed two years later inThe Journal of Symbolic Logic by none other than L. A. Zadeh, the founder of fuzzy logic; see JSL, vol. 22, no. 4 (Dec. 1957), pp. 354–355. The next series of notable mathematical logic texts to arrive on the Iranian scene were the Farsi translations of Enderton’s A Mathematical Introduction to Logic, and Hamilton’s Logic for Mathematicians, which appeared three decades later in the mid-1980’s and helped to introduce the subject to a new generation of students. In the early 1990’s Zia Movahed (an expert in philosophical logic, who is also well-known in Iran as a literary scholar and poet) authored a respectable introductory textbook on modern logic, and more recently (2002) he published a substantial textbook on modal logic, both of which will hopefully be reviewed by BSL in the near future.
