I gather that part of the point of sharing this text with a general audiance is to see whether the material strikes people as too difficult, too simplified, or assumes too much prior knowledge.
With respect to that project, it seems relevant to mention that as a reader, I am not familiar with the concept of totality, either in the work of Marx or Hegel.
I have read some short texts by Marx & Engles (Communist Manifesto, The Part played by Labour in the Transition from Ape to Man, Socialism: Utopian and Scientic) but I have not read Capital, the Grundrisse, or any Hegel. Thus, this prologue will be my introduction to the concept of totality and I will try to keep up!
