Two, even to pose the question in these terms - what is the origin of patriarchy? - helps us, by making 'patriarchy' into a specific historical phenomenon rather than something that has always existed, will always exist, and, therefore, to which there can be no alternative. I have the same problems with capitalist historiography, implying that capitalism is a transhistorical phenomenon that always was, is, and always will be. It's important to note that the critique of capitalism that has been most influential and in my view most effective, was that of Karl Marx, and his critique was precisely an inquiry into the conditions under which capitalism originated, and the conditions under which he thought it would no longer be sustainable.
