Yeah, there are plenty of counterexamples. Many articles end you up in the following closed loop:
Ancient Greek,
Greek Language,
Indo-European Languages,
Language Family. From "Language Family" there are sort of two possibilities:
1. You go to "List of language families", if you count the italicized disambiguation type text as the first link, in which case you're then sent back to "Language Family" and start looping.
2. You ignore the italicized text and click Language, which leads to Human, Taxonomy, Ancient Greek.
Either way, no philosophy.
