Kant knew that meaningless contradictions were the result of the 'dialectic method' (thesis, anti-thesis, synthesis or black hand, white hand bring them together and you have a grey hand). Despite this Hegel (following Fichte) used this machine of meaningless contradictions and set about convincing others that the nature of reality and the history of mankind was a meaningless contradiction.
Marx impressed by Hegel used dialectics in his book published in 1867 Das Kapital. Engels retooled the dialectic for Marx (he made it non-idealistic) and together they called this the 'philosophy of dialectical materialism.'
Dialectic materialism has played a prominent role on the world stage. In today's contentious political argument dialectics may mean 'how we ought to perceive things, know them and interpret them as good or bad.' Therefore it can mean religion and morals. Or it can mean that everything outside of one's perception is interconnected, contradictory and dynamic (spiritual, becoming something, he causes to become, JHWH). Or it can just mean a discourse.
Whatever it means, Hegel said that dialectic is the method by which human history unfolds. Histroy progresses, it becomes something in the present tense.
1137 AD - Hermetic thinker Joachim de Fiore born. He was a Calabrian monk who developed mystical theory of history that came to excercise an influence on German Pietism and Hegel.
Circa 1200 Joachim Fiore theorized the dawn of a new era based on his interpretation of verses in the Book of Revelation when the Order of the Just would rule. Joachim distinguished between the "reign of justice" or of "law", in an imperfect society, and the "reign of freedom" in a perfect society. He wrote of parousia and a new age of Holy Spirit. Members of the spiritual wing of the Franciscan order acclaimed him as a prophet.
