From "The Socratic Way Of Questioning":

"A #definition must be both #clear and #distinct. It must express “the perfect idea" of a thing, but if we cannot have perfect clarity, we should at least have "perfect distinctness.” so that it is not mistaken for some other thing".

In other words, if you are not able to properly describe what a thing IS, try to explain what the thing ISN'T.

Very glad I found this community. Please don't stop Question Others to Teach Ourselves😀
