The Illuminati’s purpose is to secure the ongoing survival of the human species.
Like all organisms, the human species naturally strives against extinction. Though your countries have borders and your languages have barriers, all people in all places are members of the same biological family. All humans are pieces of a collective that keeps humanity in existence.
Though you are merely a speck on the back of a grain of sand when compared to the vast number of humans born and decomposed for millennia, you are as important to your species’ survival as the greatest kings and queens.
But by nature, the human is affected by instinct, emotion, and imbalance.
