Natural Independence Phenomenon

A type of mathematical result which is considered by most logicians as more natural than the Metamathematical incompleteness results first discovered by Gödel. Finite combinatorial examples include Goodstein's Theorem, a finite form of Ramsey's Theorem, and a finite form of Kruskal's Tree Theorem (Kirby and Paris 1982; Smorynski 1980, 1982, 1983; Gallier 1991).
