Symbolic Logic: An Accessible Introduction to Serious Mathematical Logic

In recent times, I have found myself expanding a set of notes into a full-fledged logic textbook. This page includes links to download parts for sentential logic, for the first and second volumes of the text, and for the complete work. These are formatted for either single- or double-sided printing. There are also answers to selected exercises—answers are on large pages, and best viewed on a larger monitor. I am happy for anyone to use this material, and appreciate comments—which you may make via the Textbook Blog!

From the Preface: There is, I think, a gap between what many students learn in their first course in formal logic, and what they are expected to know for their second. While courses in mathematical logic with metalogical components often cast only the barest glance at mathematical induction or even the very idea of reasoning from definitions, a first course may also leave these untreated, and fail explicitly to lay down the definitions upon which the second course is based. The aim of this text is to integrate material from these courses and, in particular, to make serious mathematical logic accessible to students I teach. The first parts introduce classical symbolic logic as appropriate for beginning students; the last parts build to Gödel’s completeness and ıncompleteness results. A distinctive feature of the last section is a complete development of Gödel’s second ıncompleteness theorem. Complete preface to the textbook.
