alt Hacker NewsYes, words that label parts of continua are useful, even if they don't have well defined boundaries.
Kind of amazing how simple that fact is and how many arguments are caused by people not realising that it's true.
Here are some examples: town, artery, yellow, loud, tall, kind, woman, road...
Honestly it's hard to think of words that do not exist on a continuum. The exceptions are mostly low level maths/physics things.
Sorry, but if everything is intelligent then why is a word for it even needed like it is used today - stating that intelligence is an intrinsic property of matter, moves the discussion quite a bit, I think, as it changes what we denote there.
Unlike "artery" which certainly isn't every blood vessel or "yellow" that isn't every color.
