An undergraduate college level textbook covering first order predicate logic with identity but omitting metalogical proofs. Formal Logic is a study of inference with purely formal content. The first rules of formal logic were written over 2300 years ago by Aristotle and are still vital to many modern disciplines like Linguistics and Computer Science.

A very accessible mathematical classic. It sets forth in elementary form the logical definition of number, the analysis of the notion of order, the modern doctrine of the infinite, and the theory of descriptions and classes as symbolic fictions.

The purpose of this book is to teach logic and mathematical reasoning in practice, and to connect logical reasoning with computer programming. The programming language that will be our tool for this is Haskell, a member of the Lisp family.
