do you know about Darwin? natural selection clearly doesn't entail social processes now on whether ideas are material, i think the issue is around whether the material conditions lead to the ideas or if it can be vice versa sometimes, which is what i believe is increasingly true, now that everything is built on a materialist basis at the start anyways is obvious, but this is a philosophical conversation and doesn't pertain to the fact that social processes are clearly not natural selection (unless you're fash or in fash world)
