Full Idea

Water is said not to be 'dissective', since there are parts of any quantity of water which are not water.

Gist of Idea

Dissective: stuff is dissective if parts of the stuff are always the stuff

A Reaction

This won't seem to do for any physical matter, but presumably parts of numbers are always numbers.
