'equality' and 'identity' are similar too, so the whole answer would make  
no sense in that case. You can't explain identity based on things that  
aren't identical. A fine grained question for a fine grained difference  
requires a fine grained answer.

I didn't meant to be rude at all - and I apologize to Mr. Lie. The  
explanation for such strong "No" was in the paragraph below it (the idea  
was to say: "No to this, yes to that")
