I'm trying to find the following quote:  "Our schools should be a
place where children have been made to work up to their individual
potential, where talent is placed in high posts, and where the worth
of the individual is stressed.  In this sense the individual qualities
of humility, charity, contentment, and all the pleasures of gratitude
or admiration are to be included in their education."

Hello.

First of all, it's not an exact quote.  It's a partial quote from C.S.
Lewis' "Screwtape Proposes a Toast."

The phrases "humility, charity, contentment, and all the pleasures of
gratitude or admiration," "children have been made to work, and 
"where talent is placed in high posts" are so unique that it's highly
unlikely that there is any source for the quotation other than C.S.
Lewis.

search strategy:
"pleasures of gratitude"

I hope this helps.

Thanks so much - I was sure it was C.S.Lewis but I had gone over and
over my books and couldn't find it.  I forgot Screwtape!  The "quote"
was the reversed Screwtape version - thus my inaccuracy.

Thank you for the tip.
