Dialectic

Hegel (method)

The self-movement of thought through contradictions. Not a formal argumentative scheme (thesis-antithesis-synthesis), but the demonstration of how determinations turn into their opposite and must be sublated.

Origin

Plato's dialectic (dialogue). Kant's dialectic (illusory problems). Hegel's dialectic: productive contradictions as the motor of development.
