Need an elementary logic book that completely covers the completeness theorem (no pun intended).
The discussion centers on the search for an elementary logic book that thoroughly covers Gödel's completeness theorem. Participants clarify that Gödel's completeness theorem is distinct from his incompleteness theorems and suggest that any good introductory text on formal logic should include it. Notably, Nagel and Neumann's "Gödel's Proof" is recommended as one of the simplest resources available. The conversation emphasizes the need for clarity regarding which completeness theorem is being referenced, as there are multiple theorems across different contexts.
PREREQUISITESStudents of formal logic, educators seeking teaching materials, and anyone interested in the foundational aspects of Gödel's completeness theorem.
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)
