The Transition of Epochs

For me, I understand historical materialism to be a specific definition or an explanation on the transition of epochs as it pertains to production and political economy. And that's how I understood it. But when I heard the presentation of others, and I think Robinson does the same, that wasn't why, yeah, it wasn't the same thing he seems to be speaking to. So in essence, but in essence, he says, I have interpreted your first main phrase in the following way. According to the materialist conception of history, the factor which is in the last instance decisive in history is the production and reproduction of actual life. More than this neither Marx nor myself ever claimed.
