What is a concept ?

OK, if there no need to define such segmentation then doesn't the word "thing" via your brand of constructed language do just that, ie partition?

Vague thoughts, vague language.

Agreed, "thinging" is "partitioning", but such partitioning is dynamically two way. The "hungry I" is co-extensive and coexists with a "food/non-food" partitioning. ( Charlie Chaplin eats his boot !). What constitutes "food" is dependent on the state of the conceptualizer and vice versa, but that argument can be applied to all "things".

...such is the problem of trying to transcend language with language !

I'm speechless.

I like zetherin's response, I like fresco's response and I like spendius' response. It's an equilateral triangle of agreeableness eclipsing Pythagoras' theorem.
