Joanna Stempczyńska,Edward KąckiThis first chapter is an incomplete summary of classical intuitive logic. The importance of tackling this at the very beginning—of a book and of a curriculum—cannot go amiss.

David Hawkridge,John Jaworski,Harry McMahonThis chapter develops set-theory topics that are useful in algebra and topology. It will give us the excuse to provide proofs to the Deduction and Soundness Theorems ., ., and introduce the first elements in model theory. The final part attempts to contextualise the scientific revolution unleashed by Gödel’s theorems.
