MATH.22:3 - Forces

ForceTension
GeneralityFewer assumptions can cover more structures while supporting fewer conclusions.
Stronger constructionsAdded axioms can supply an object or simplify a proof while excluding intended cases.
Familiar notationA new symbol can abbreviate an existing construction or introduce a new assumption.
Proof reuseA theorem may remain valid even when its familiar proof uses a removed axiom.
Useful metatheoryA small countermodel can settle a local question; a consistency claim about a foundation can require much stronger work.
Computational useAn existence principle can support a mathematical argument while leaving an obtaining procedure to be supplied.
