I won't try to define anything. If you think you can: feel free to do so. But before I believe you you have to tell me the difference in taste between an orange and a tangerine.

Well I think that you can only give examples. It's one of those things everyone knows without ever being able to express it in words without applying force to simplify it.
 Where does the beach end, and where does the ocean begin? Where is the exact border between, say, the US and Canada? Is this grain of sand US or Canadian property?

I find that if you add a tree or put in a different sky, change eye colour of a person, or the colour of a car you are manipulating. When you get rid of a person who was standing there and you wish he wasn't, or of a Coke bottle you couldn't hide when you were at the spot, it's not.

There is and will always be a twilight zone, a chaos element. That's life. And I love that.

There are no Borg. All resistance is fertile.
