You have to use the slug from the wiki page. `Jell-O` to `Philosophy` works.

Oh, it's case sensitive! Thanks.

It seems you are right to doubt! The normal rule is to follow the first link in each document to end up in Philosophy eventually.

From Jello I followed this route:

Jell-O -> All caps -> Typography -> Typesetting -> Written Language -> Language -> Communication -> Information -> Abstraction -> Rule of inference -> Premise -> Proposition -> Philosophy of Language -> Philosophy

If following the "rule" to ignore parenthesized and italicized links:

Jell-O -> Brand -> Business -> Trade -> Goods and services -> Tangibility -> Perception -> Sense -> Biological system -> Biological network inference -> Inference -> Logical reasoning -> Mind -> Thought -> Cognition -> Mental state -> Mind (Loop!)

Apparently there is now a funnel into another attractor via "law" and "state" and then goes around a loop "mind", "thought", "cognition" and "mental state" and back to "mind".

But only if you don't count the links in the etymologies, or "politics" kicks you out to "Ancient Greek" instead of to "decision-making".
