The fundamental idea of Platonism is that any such-and-such thing is such-and-such because it participates in the Form of a such-and-such thing. There are a lot of arguments against this view. Four of these arguments arc of regress ad infinitum from. One of these arguments is famous “The third man” argument. In this paper author argues that none of these four arguments is valid. Therefore, platonistic ontology is immune to arguments of this form.
