Abstract： In order to fundamentally eliminate all kinds of paradoxes existing in mathematic foundation and make mathematics architecture on a highly reliable basis, it was found that formal logic can only be used in the discussion domain (called the feasible domain) in which all of the three laws, i,e, the law of identity, the law of non-contradictory and the law of excluded middle are hold true. Otherwise, various errors including public opinion will occur. It was concluded that in feasible domain, as long as the premise is reliable and the derivation is strict, no paradox exists. Some historically famous paradoxes such as liar paradox and barber paradox were therefore analyzed. At the same time, the logical mistakes in the application of Piano axiom, in the proofs of Cantor's theorem, the interval method and diagonal argument were pointed out. Suggestion for a uniform definition of natural numbers, rational numbers and irrational numbers to avoid any errors was therefore proposed. " "
