Folklore says if you take any article on wikipedia, and click on the first link in the article text not in parentheses or italics, you will eventually end up at Philosophy. Mat Kelcey analyzed every article on wikipedia, and it is mostly true. About 3% of articles don’t make it to philosophy. But the interesting thing to emerge from this data, is that it’s actually a small loop of articles that are at the core of everything on wikipedia. Philosophy is just one of them.
The loop is:
Philosophy -> Reason -> Natural science -> Science -> Knowledge -> Fact -> Information -> Sequence -> Mathematics -> Quantity -> Property (philosophy) -> Modern philosophy -> Philosophy
So by extrapolation, every idea in the entirety of human knowledge is built on this backbone.
