Today I read a published paper titled “The Foundation of a Generic Theorem Prover”

Taking another crack at understanding proofs and how they can be automatically (interactively) solved. Still don’t get it. I feel so fucking dumb.

The abstract is:

*Isabelle is an interactive theorem prover that supports a variety of logics. It represents rules as propositions (not as functions) and builds proofs by combining rules. These operations constitute a meta-logic (or `logical framework’) in which the object-logics are formalized. Isabelle is now based on higher-order logic — a precise and well-understood foundation. Examples illustrate use of this meta-logic to formalize logics and proofs. Axioms for first-order logic are shown sound and complete. Backwards proof is formalized by meta-reasoning about object-level entailment. Higher-order logic has several practical advantages over other meta-logics. Many proof techniques are known, such as Huet’s higher-order unification procedure.*
