Full Idea

If whatever thing in world w6 it is that resembles you more closely than anything else in w6 is nevertheless quite unlike you; nothing in w6 resembles you at all closely. If so, you have no counterpart in w6.

Gist of Idea

If the closest resembler to you is in fact quite unlike you, then you have no counterpart
