Full Idea
The recognition of the fact of continuity is logically independent of the possession of sortal concepts, whereas the formation of sortal concepts is at least psychologically dependent upon the recognition of continuity.
Gist of Idea
Recognising continuity is separate from sortals, and must precede their use
