You see the problem. If "You can't define a word any way you want" is a good philosophy lesson, it should be a good philosophy lesson _independently_ of the particular word in question and _independently_ of the current year. If we've _learned something new_ about the philosophy of language in the last ten years, that's _really interesting_ and I want to know what it is!
This is _basic shit_. As we say locally, this is _basic Sequences shit_.
