The full name of this work is Capital: A Critical Analysis of Capitalist Production. Engels adds to the preface, which is really the first of three volumes, that "Capital" is the "Bible" for the working class. This raises an eyebrow, because Engels complains elsewhere that workers don't even know who Samson was, and this "Bible" of Marx, being a lengthy discourse on economics, has so far never risen above the dryness of the most dry portions of the Bible, plus, the length of Marx's volume one at 40 hours of listening is the same as for the entire Bible. Clearly only the mentally ill would read Marx's work through, or if they had not already been mentally ill, then they certainly would be if trying to read and follow all his arguments from beginning to end, which I must keep in mind as I proceed!
At this point I have listened to a few hours of discussions of how many yards of linen is worth a coat as Marx tries to develop the concept of value. Marx has now sensitized me that my last sentence used both the Latin word "value" and the Teutonic word, "worth", indicating my conflicted capitalist upbringing that resulted from a blend of the passionate Irish with the calculating Anglo-Saxon. This eventually proceeds into the concept of money and price, which still needs a few hours of clarification.
One feature of any economic discussion is that it can never be sufficiently caveated and remain finite in size. Thus, Marx finds cause to quote and quibble with everyone, but I am in doubt as to whether or not any of Marx's quibbles put at risk the content of an argument. Mixed in with this are a number of remarks going back to classical writers such as Homer and Aristotle. So what I see so far is that Marx is discussing capitalism, coming to descriptions that are essentially identical to capitalist economists, while having left a record of quibbles.
Having gone through several of the works of Marx and Engels, I am now leaning to a viewpoint that is quite different from the one that I held before I started. Namely, that Marx and Engels never defined a system and to speak of "Marxism" is nonsensical. All that was proposed by Marx and Engels is that capitalism should be overthrown. Marx has the notion that social circumstances change over time, necessitating different political conditions which should naturally evolve, but capitalism has thwarted this process. Capitalism stands in the way of this natural evolution. I tend to an opposite viewpoint, that capitalism is the natural process of evolution, whereas intellectuals forever desire to impose themselves, creating chaos.
