There have been interesting debates between Hilary Putnam and his critics on his argument against metaphysical realism. The purpose of this paper is to analyze the nature of the debates and to defend Putnam's position in several important points. There are two types of criticism, one is to defend the correspondence theory of truth, and the other is to defend metaphysical realism without the correspondence theory of truth. Putnam seems to be able to answer these criticism effectively. Of course this isn't exhaustive survey, but I think this limited survey is enough to indicate the remaining problems.
