Baron von Lotsov: Marx was motivated in his youth to proffer a repudiation of Hegel. Hegel's first question, 'what causes society to change', is the basis of Marxism. Hegel was an idealistic philosopher (in the philosophical sense of the word) but Marx argued that world of ideas (thesis, synthesis and antithesis) was secondary to that relationship of human beings to their material world which was imposed upon them independently of their will. (He was a materialist in the philosophical meaning of the word.) Marx believed that capitalism was the most remarkable system of either ancient or modern times, but like all previous economic systems it was doomed due to its inherent contradictions. The capitalists would make a world in their own image, but they would be their own grave diggers. Were capitalists evil people,: no said Marx, they are what capitalism required them to be. Anarchism cannot be linked to Marxism in the way you suggest. Was it Mikhail Bakunin the Russian anarchist that you had in mind? Presumably you could equally argue that theology and secularism could be deemed the interplay of opposites? I'm not sure where that line of reasoning leads. For want of clarity I depart this place.
