About
dialectic
In classical Greece, a process of discussion that is illustrated in
Plato 's dialogues was called dialectic.  It is a way of questioning and conversing and reasoning. 
Kant referred to the "transcendental dialectic" as metaphysical reasoning that tried, without success (or possible success) to figure out what the truth was beyond our senses.  The German philosopher,
Hegel , applied the term to a process of development in which one idea (the thesis) begets its opposite (the antithesis) and the two come together to form a synthesis.
Marx built on this Hegelian notion of dialecic in his version of dialectical materialism.
