The project we can generally call the Enlightenment was about including humanity is one common category. It’s economic and political arms involve incorporating difference and investing in unknowns we can call excess.
The failure of this project is actually the culmination of its effort, its fruition. Where ever difference may appear, it’s manner of viewing the universe has filled in, colonized every possibility of thinker including ways to think about thinkers and thoughts that could not think of have a thought.
The enlightenment and its project of colonialization continues because thought itself is understood commonly as a particular set of instructions and descriptions that most people are simply unable and will not ‘think’ outside of. This is so much the case, the project so solidified, that even philosophy itself thinks that it is able to overcome this ideological theological maxim.
What we call ‘Esoteric’ is that manner of coming upon the universe which, for any group of human beings, cultures or “religions”, is unable to be communicated to the aggregate of constituents.
Confusion arises in the world, dissolution of group coherence, when everyone one is assumed to be party to all ability of knowing and thinking in potential. Individual withdraw into subjectivity, the atomization of the human group, the dividing or separating of things along “improper” junctures, causes demoralization in the groups constituents and an ability for large exploitation of those individuals due to the conceptual excess which arises from the ‘fission’ of people who would otherwise see themselves as a whole being intimately involved with a coherent and meaningful group.
