Assuming no previous study in logic, this informal yet rigorous text covers the material of a standard undergraduate first course in mathematical. From this perspective the principal asset of Chiswell and Hodges’ book For a senior seminar or a reading course in logic (but not set theory). Maybe I understand it now Your concern is right: what the exercise proves is something like: if Γ ⊢ ϕ, then Γ [ r / y ] ⊢ ϕ [ r / y ],. i.e. every occurrence of.

The really cute touch is to introduce the idea of polynomials and diophantine equations early — in fact, while discussing quantifier-free arithmetic — and to state without proof!

The other book is The Mathematics of Logic by Richard Kaye CUP which is aimed perhaps at somewhat more sophisticated students with a wider mathematical background, but it is very good at signalling what are big ideas and what are boring technicalities.

Space, Time, and Stuff Frank Arntzenius. This is notionally targetted at third year maths undergraduates which these days, in most UK universities, sadly isn’t saying very much. Incidentally, Kaye uses, as his way of laying out formal proofs, a Fitch-type system — which I think is the right choice if you really do want to stick as closely as possible to the ‘natural deductions’ of the mathematician in the street, though I’m not sure I’d have chosen quite his rules.


Again we get a soundness and Hintikka-style completeness proof for an appropriate natural deduction system. Kit Fine and the All in One Post as a guest Name. Two basic themes in recent cognitive science studies of actual human reasoning are also introduced. Posted by Peter Smith at 1: I guess it’s pitched at a similar audience who saw at least one completeness proof?

You have reached the blog’s old address. Let me highlight three key features of the book, the first one not particularly unusual though it still marks out this text from quite a few of the older, and not so old, competitorsthe second very unusual but extremely welcome, the third a beautifully neat touch:. Rigorous proofs of the adequacy and completeness proofs of the relevant logics are provided, with careful attention to the languages involved.

Maybe I understand it now Would you say that your example given here is a counterexample to the proposition the exercise asks us to prove? Sign up using Facebook. The book defines LR as a “language of relations”.

I interpret the question above as follows. Sign up using Email and Password.

Mathematical Logic

Then we get the quantifier-free part of first-order logic, dealing with properties and relations, functions, and identity. But the core key sections on soundness and completeness proofs and associated metalogical results are second to none for their clarity and accessibility. Hellman on extensibility Two new logic books Showing and saying Me and J. After a short interlude, Ch. The Hintikka-style completeness proof for the new logic builds very nicely on the two earlier such proofs: Bayes’s Theorem Richard Swinburne.

Logic Matters: Two new logic books

He has published a monograph on lamda-trees, which are generalisations of ordinary trees. Wilfrid Hodges achieved his DPhil at Oxford in for a thesis in model theory mathematical logic.

In the last few days, I’ve got two newly published introductory logic books, both relatively short and aimed at similar audiences. Besides this book, he has four other textbooks mathematidal logic in print, at levels ranging from popular to research.

The Linda Problem 7. Mathematics Stack Exchange works best with JavaScript enabled. The treatment of the semantics without quantifiers in the mix to cause trouble is very nice and natural; likewise at the syntactic level, treatment of substitution goes nicely in this simple context. Your concern is right:
