Quine's book is of first-rate quality, and presents the materials of modern formal logic in a masterly fashion...A superb text: authoritative, mature, and brilliant and original in its exposition. (Ernest Nagel)
It is admirably precise and it is written with a deliciously light touch. (Joseph S. Ullian)
For a treatment of such modest size, it abounds in exciting ideas, freshness of perspective on old logical and philosophical problems, and in lucid and exact analysis. (R. J. Trayhern)
From the Back Cover
This widely used textbook of modern formal logic now offers a number of new features. Incorporating updated notations, selective answers to exercise, expanded treatment of natural deduction, and new discussions of predicate-functor logic and the affinities between higher set theory and the elementary logic of terms, Quine's new edition will serve admirably both for classroom and for independent use.
