In this week’s discussion, I ask you to think about and explain an inner contradiction within the Communist Manifesto. The 1848 text puts forward the following theory: the history of humanity is just a succession of times of oppression by the bourgeoisie over the working class interrupted by a few revolts led by the working class. Marx and Engels predicts that there is an upcoming and unavoidable revolt led by the working class that will break this vicious cycle. They argue that the Industrial Revolution has put too much power in the hands of the bourgeoisie, which led to too much suffering for the working class, and that it is not sustainable much longer. Knowing this, why would Marx and Engels praise so much the success and contributions that the bourgeoisie made to the world? For example, "The bourgeoisie, by the rapid improvement of all instruments of production, by the immensely facilitated means of communication, draws all, even the most barbarian, nations into civilization." (The Communist Manifesto, p. 3)
