I discuss the whole concept of 'intelligence' and if it even means anything. i think it doesn't.

The book I mentioned: Kazuo Ishiguro's Never Let Me Go
[spoilers!]
The concept: the main characters are 'clones' who were brought to life to have their organs harvested.
At school, they had a 'gallery', where the best art is displayed. They took it seriously.
Some had a theory that students who can prove they're in love can get a 'deferral', so have a couple of years together before going for the donation.
Tommy, one of the main characters, thinks that the art in the gallery shows their souls... and souls reveal whether you're truly in love.
They went back to the headmaster, who told them, "The gallery is just to see if you have souls at all."
