Okay so shocked by iMac's definition of illuminati..

I find it very interesting not only the parallel they draw between the freemasons and illuminati but most importantly that defines first and foremost not as a "conspiratorial group of people that supposedly run the world etc." but literally as they would define themselves.

illuminati |iˌloōməˈnätē|
plural noun
people claiming to possess special enlightenment or knowledge of something : some mysterious standard known only to the illuminati of the organization.
• ( Illuminati) a sect of 16th-century Spanish heretics who claimed special religious enlightenment.
• ( Illuminati) a Bavarian secret society founded in 1776, organized like the Freemasons.
