Abstract
In my critique of professor mandelbaum's "the historiography of the history of philosophy," i raise three queries. the first is about a "methodological" question, roughly, "what is to count as philosophy?" the second concerns a part of the central thesis, namely, that (for the most part) a major philosopher's "primary beliefs" do not derive from his criticism of other philosophers. third, i raise some questions which appear to lie behind mandelbaum's proposal regarding what is to count as history of philosophy. my conclusion is that his proposal is both ill-founded and excessively restrictive
