Pearl S. Buck on euthanasia

Having seen it spelled every which way lately, I was double-checking the spelling of euthanasia in my favorite dictionary (The Penguin English Dictionary, 2nd Edition) -- and found that the definition included this quote (this dictionary is good about including word histories and quotes):

Euthanasia is a long smooth-sounding word, and it conceals its danger as long, smooth words do -- Pearl S Buck

Update: I've found the quote in a longer context, and find it's even better there. See here, at the blog Soli Libri.
