ZFC is shown to be inconsistent

It is shown that ZFC is inconsistent
http://www.scribd.com/doc/40697621/MathematicsEndsinMeaninglessnessieselfcontradiction
in ZFC IS AN AXIOM CALLED THE Axiom schema of specification
http://en.wikipedia.org/wiki/Zermelo%E2%80%93Fraenkel_set_theory
3. Axiom schema of specification (also called the axiom schema of separation or of restricted comprehension): If z is a set, and \phi\! is any property which may characterize the elements x of z, then there is a subset y of z containing those x in z which satisfy the property. The "restriction" to z is necessary to avoid Russell's paradox and its variant
the axiom of separation is used to outlaw/block/ban impredicative statements like Russells paradox
now the axiom of separation of ZFC is it self impredicative as Solomon Ferferman points out
http://math.stanford.edu/~feferman/papers/predicativity.pdf
"in ZF the fundamental source of impredicativity is the seperation axiom which asserts that for each well formed function p(x)of the language ZF the existence of the set x : x } a ^ p(x) for any set a Since the formular p may contain quantifiers ranging over the supposed "totality" of all the sets this is impredicativity according to the VCP this impredicativity is given teeth by the axiom of infinity
thus it outlaws/blocks/bans itself thus ZFC contradicts itself and 1)ZFC is inconsistent 2) that the paradoxes it was meant to avoid are now still valid and thus mathematics is inconsistent Now we have paradoxes like Russells paradox BanachTarskin paradox BuriliForti paradox Which are now still valid
ZFC is shown to be inconsistent by australias leading erotic poet colin leslie dean
