At one point some Greeks were trying to define the word Man, they came up with a featherless biped, and the next day someone released a plucked chicken in the school.
There are some words that are notorious for being hard to define. What they figured out was for those words to instead build up criteria.
Not just someone, the legendary philosopher Diogenes. One of my favorites stories is that one day he was cleaning veggies in a river or something, when Plato walked up and was like "You know Diogenes, if only you could pay taxes to the king you wouldn't have to wash vegetables." And Diogenes responds, "You know Plato, if only you could wash vegetables you wouldn't have to pay taxes to the king."
I always thought the time span of philosophers existing was so large, none of the famous ones would be alive close enough for them to have had any conversation.
But turns out it is some sort of Marvel Cinematic Universe type of shit where they all lived together.
