Quine has put forward several arguments against the Analytical/Synthetic Distinction in the paper named "Two dogmas of empiricism" (I have not read the paper myself), one of arguments being that there is no non-circular definition of Analytic. while I argue with Quine on that, I do not find that to be a problem since I don't have any reason to think that Circular Definitions to be a problem. since Definitions are ultimately circular (Since the definition of words are relies on the use of other words), meaning that you have to reject the use of language all together (which is absurd since you have use language to come to that conclusion). Why are circular definitions bad definitions?

You should certainly read "Two Dogmas of Empiricism" -- it's one of the best-known papers in analytic philosophy and can be said to have set a large part of the agenda for Anglo-American philosophy since its publication in 1951. Better to read the paper itself, anyway, than to read things things about it, as you evidently have. Circularity doesn't itself play that much of a role in Quine's paper. His attack on the analytic-synthetic distinction is waged on two broad fronts (to oversimplify a bit), a logical one and a linguistic one. The logical one is largely implicit in "Two Dogmas" but gets more attention in some later writings of Quine's. It derives from Gödel's first incompleteness theorem, which showed that there can be (under certain conditions) true sentences in an axiomatically defined language not provable from its axioms (i.e. not "analytic" as that is understood by e.g. Frege). So if you want a distinction between sentences that are simply an artifact of the language you've chosen and...

Does Quine's critique of the analytic-synthetic distinction also apply to circular definitions? For example: a 'bachelor' is an 'unmarried male' seems analytic, and 'bachelor' and 'unmarried male' are synonyms. But consider: 'condescension' means a 'patronizing' attitude. Of course, 'condescension' and 'patronizing' are defined in terms of each other. Are all definitions that are circular in this way still susceptible to Quine's critique of the analytic-synthetic distinction, because they trade on the synonymy of the definiens and definienda?

This question reflects what I think is a widespread conception of Quine's critique, which is that it applies to ordinary colloquial language. Quine actually went much further than that. He was fundamentally skeptical of synonymity as well, and thought he could cast doubt even on the idea that you could stipulate synonymity, by setting up, say, an axiom system or, on a less formal basis, local "meaning postulates." You can regiment all you like, but you can't control what becomes of your regimentations; the most eloquent recent articulation of this view, in endlessly fascinating scientific detail, is Mark Wilson's work (see esp. his book Wandering Significance ). So the answer to the question is "yes." Quine didn't think in the local "circularity" terms in which the question is posed; he considered all human knowledge, starting with the most elementary common-sense knowledge and reaching to the most abstract representations of theoretical physics, to be one gigantic reciprocally-supportive circle...
