Re: Ken ReganThe Shapes of Computations

The insight that it takes to find a succinct axiom set for a theoretical domain falls under the heading of abductive or retroductive reasoning, a knack as yet refractory to computational attack, but once we’ve lucked on a select-enough set of axioms we can develop theorems that afford a more navigable course through the subject.

For example, back on the range of propositional calculus, it takes but a few pivotal theorems and the lever of mathematical induction to derive the Case Analysis-Synthesis Theorem (CAST), which provides a bridge between proof-theoretic methods that demand a modicum of insight and model-theoretic methods that can be run routinely.
