Manichaean

Through them passed not only the traders of the Silk Route[…] but also lone Buddhist monks carrying precious cargoes of scrolls in their backpacks, white-robed Manichean sages from Iran and austere Nestorian clerics who founded Christian monasteries even in remote Tibet.

Detractors of Mr. Nixon will decry the book's [1999: Victory Without War] obsession with potency and winning[…] as well as with a Manichaean view of a world that he sees as divided between the bad Soviet Union and the good United States.

Barack Obama spoke of a world without these Manichean dualities. He dismissed the notion of “red” and “blue” America.

Once again, we see a Manichean world not unlike that of conspiracists: you can be good or you can be evil.
