Last and First Men tries to bypass theory, but it also contains a very complex analysis of world history using a form of ‘systems analysis’, with remarkable results. But those results can be kept in the background, as the issues of economies in the present enable social activism to proceed on the basis of free agents creating or deconstructing economies. The whole emphasis on historical materialism is bad theory, a straightjacket that makes simple moral activism delusional. Come on, how did we get stuck in this? Marx was too concerned to be brilliant and in the mode of the times, positivism. But we need a new approach now, and to do that we can simply bypass historical materialism.
The Appendix to LFM is a interesting jaunt into a strange enchanted woods, and the result gives us a framework that is very useful for a larger social analysis.
