....programming are incautiously moving away from the standard mathematical practice with consequences that can harm only them. 3 Second Order Theory of Finite Sets: FSI We axiomatize the theory FSI of nite sets in the style of the set theory with classes of von Neumann, Bernays, and G odel (VBG) [6] as a two sorted ( rstorder) theory. Upper case variables range over the sort of classes and the lower case variables over the sort of ( nite) sets. There is a single non logical symbol 2 of class membership. The atomic formulas are 1 2 2 and 1 = 2 for any combination of set and class ....
....sets. The domain of classes is formed from those subsets of H which are de nable by comprehension from restricted formulas [x] with at most x free. There is nothing impredicative about the construction of the last domain. Its elements are generated from the class E by the Weyl G odel operators [4, 6] in arguments X and Y : X Y X Dom(X) V X X Cnv 1 (X) Cnv 2 (X) The operators satisfy: hx; yi 2 E x 2 y x 2 X Y x 2 X x 2 Y x 2 X x = 2 X x 2 Dom(X) 9y hy; xi 2 X hx; yi 2 V X y 2 X hx; yi 2 X hy; xi 2 X hx; y; zi 2 Cnv 1 (X) hy; z; xi 2 X hx; y; zi 2 Cnv ....
