The Axiom of Choice
... that in that case, if we had any finite number of cases to check, and we can prove that the first is true and each one implies the next, then we will have that all of them are true, without any “axiom of induction.” The trouble comes when we try to do this for an infinite number of cases: a “proof” ...

... logic L defined by a set of axioms and rules, Γ `L α means, in general, that there is proof in L of α from the premises in Γ. The subscript may be omitted when obvious from the context. If Γ is empty we say that α is a theorem. The propositional three-valued logic known as L3 was first proposed by J ...
