Principally I am a materialist, particularly of the Marxist variety. I am still learning about the subject though, and claim to be no expert. The first work I read and understood was Lenin's "The Three Sources and Three Component Parts of Marxism", and I quickly moved onto his "State and Revolution" and Marx's "Wage-labor and Capital" and "Value, Price, and Profit". These are the foundational works I have continued to build off since. I have read shorter texts particularly on Dialectical and Historical Materialism, as well as Guerilla Warfare and Peoples war. I identify as a Marxist, and have many Hoxhaist or Maoist tendancies, but I was radicalized into those strains through the internet and not reading.
What I am doing now to correct my line is attempting to find a strong foundation, before jumping to conclusions and poor analysis.
Currently reading:
The German Ideology - Karl Marx and Frederick Engels - 1845
and
Imperialism, the Highest Stage of Capitalism - Vladimir Lenin - 1916
