Then Zick must be doing it in the dark because I certainly am not.

Which axioms do you claim to be true, and why those, Zick?

Zick claims my logic is circular, but can give no evidence of that 
circularity. 

If Zick wishes to make a claim of another's illogic, and wishes to be 
believed, he should provide at least some evidence in support of that 
claim.
Such claims without evidence are instances of the fallacy of argumentum 
ad hominem.
