ZFC only resolved Russell's Paradox because it tossed out
the incoherent foundation of https://en.wikipedia.org/wiki/ Naive_set_theory
Actually Zermelo did it. The F and C are simply minor improvements on
other aspects of the theory.
Thus establishing the precedent that replacing the foundational
basis of a problem is a valid way to resolve that problem.
No, that does not follow. In particular, Russell's paradox is not a
problem, just an element of the proof that the naive set theory is
inconsistent. The problem then is to construct a consistent set
theory. Zermelo proposed one set theory and ZF and ZFC are two other
proposals.
My view is that the same kind of self-reference issue that
showed naive set theory was inconsistent also shows that the
current notion of a formal system is inconsistent.
From the proof of the exstence of Russell's set it is easy
to prove that 1 = 2. As long as no proof of 1 = 2 from a
self-reference in a formal system is shown there is no
reason to think that such system is inconsisten.
In other words you presume yourself to be all knowing about this.
As usual, your "In other words" is a lie.
