A very nice analogy, taking us even deeper into fuzzy territory...

I don't think it is directly related to that particular
difference. But it certainly is related to a more general
form of it - seeing each 'unit' in its own domain, and
some domains being fully isolated from others.

We all agree on what 'red' means. Because we have learned
the meaning of that word by association.  But do we 'see'
the same thing ? AFAIK, that is impossible to verify.
