The Iceberg of Ideas

Ideas (or worldviews, which are sets of multiple ideas, which I see in a modular manner) can be conceptualized as an iceberg: at the top there are "mainstream" ideas, then the further you go down, the less mainstream those ideas are. If you go deep enough, you get ideas that are in no formalized worldview, those are views, ideas and beliefs you can arrive to by yourself. Those ideas tend to be very abstract, occult/esoteric, the kind of ideas that psychiatrists would call "schizophrenic" and that a Muslim or a Christian would think have come from Satan itself. Where ideas are located within the iceberg depends on the culture: for example, in the Aztec Empire, torturing and sacrificing children to Tlaloc in order to get rain was mainstream, and therefore at the top of the iceberg, whereas in modern "western" (i.e. Anglo-European i.e. Europe + English-speaking countries)) culture, that idea would be much deeper in the iceberg. Deep enough into the iceberg, you get ideas that no culture, and not even very small ideologies or cults have ever thought about. and I think I may be able to access that part of the iceberg and bring some of those ideas to this website. I hypothesize that you can't go too deep, that there's some sort of cognitive barrier that prevents a human from accessing the deepest parts of the iceberg. I call that part "The Marianna". If my hypothesis is correct, then there's a limit to what a human can think. More stuff coming soon...

Possible paradigms

Paradigm 1: the visible part of the iceberg are the mainstream ideas, whereas everything else is buried underwater. The depth indicates how unpopular and/or unknown an idea is.
Paradigm 2: same as paradigm 1 except that subcultural ideas are also on the visible part of the iceberg, as long as 'the average person' is aware that there are people who believe in those ideas. More obscure ideas are buried underwater, and the depth indicates how unknown (rather than how unpopular) an idea is.
