Many people know dialectics didn't come from Lenin or Marx (in fact dialetical materialism came from a guy called Dietzgen that no one reads anymore), but what some don't know is that they also did not come from Hegel. The origin of dialectics ultimately goes back to the Jewish mystical tradition of Kabbalah and the Sephirot.

Unironically, knowledge of the Sephirot and their connection to dialectics is something the anime Neon Genesis Evangelion assumes the viewer to have.
