(I've just read The Communist Manifesto and Engel's "Socialism". They are both very incisive analysts, although the flaws in their predictions are obvious today - and Engels is a good historian and a very amusing writer! I had not expected him to be so entertaining to read. Maybe now I can better respond to some of your comments on my metas, re: Joss and the working class?)

Well, the Communist Manifesto is a political pamphlet to urge the European workers into unity and action. It is not a deep analysis but rather an inspirational speech, so to speak. :)

And yes, Engels is great! A deeply emphatic human being who truly wants his fellow humans to live in peace and happiness. He wrote at length about racism, gender inequality, history. He himself came from a position of utter privilege, being born into a wealthy entrepreneur family owning several factories. he himself never had to fight, or work but still he devoted his whole life to the finest cause of humanity:

"Man's dearest possession is life. It is given to him but once, and he must live it so as to feel no torturing regrets for wasted years,
never know the burning shame of a mean and petty past; so live that, dying he might say: all my life, all my strength were given to the
finest cause in all the world - the fight for the Liberation of Mankind." Nikolai Ostrowski

While Marx is like the mind of socialism, Engels is the heart.

(Though Marx is amusing, too in a totally intellectual way: He wrote so sharp and scathing critiques of other philosophers and thinkers of his time and nobody ever got the better over him. Sharp, sharp mind and a very sarcastic humor.)
