THIS is the one I remembered, the one I was looking for, the one that has stuck with me through the years:

“Don't you know....don't you know that there are things, in the best of us, which no outside hand should dare touch? Things sacred because, and only because, one can say: 'This is mine'? Don't you know that we live only for ourselves, the best of us do, those who are worthy of it? Don't you know that there is something in us which must not be touched by any state, by any collective, by any number of the millions?”
