Need an elementary logic book that completely covers the completeness theorem (no pun intended).
The discussion revolves around the search for an elementary logic book that thoroughly covers the completeness theorem. Participants explore the meaning of the completeness theorem and its relation to Gödel's work, as well as the appropriateness of various texts for this topic.
Participants express differing views on what is meant by the completeness theorem and whether it can be adequately covered in an elementary logic book. There is no consensus on specific texts or the sufficiency of coverage.
Uncertainty exists regarding which completeness theorem is being referenced and the definitions of "elementary" and "basic" in the context of logic texts.
Hurkyl said:Gödel proved a completeness theorem in addition to his two incompleteness theorems for logic. There are probably other 'completness theorem's too both in logic and in other contexts, so it's not clear that's the one the OP means.
If the OP does mean Gödel's completeness theorem, I imagine it should be in just about any good introductory text on formal logic. (i.e. a text meant to teach the discipline of formal logic, rather than an 'introduction to proofs in mathematics'-type book)
