While true the Illuminati do reference duality the rationale behind it is left out of this article. The use of duality in Illuminati is the create a synathesis.
- Thesis – A theory, the pro.
- Antithesis – A secondary theory, the con.
- Synthesis – A third theory, the neutral.
In creating the synthesis you achieve balance and perfection via a dialetical argument. That is to say light and darkness create one whole day.
Aside from obvious symbols of duality, I see no real symbolism of Illuminati specifically in the advertisement. What I do see is a dead Old World Order attempting to maintain a clenching on control by faking cliquish and immature bravado that holds no meaning at all. It could be funny if it were not so sad.
