If it is foolish to think that we can carry with us all the good things from the past—from our personal past or that of our culture—while leaving behind all the unwanted baggage, it is a counsel of despair and, I think, another kind of foolishness to think that if we leave behind the errors and miseries of the past, we must also leave behind everything that gave that world its savor. Wisdom lies in discernment, and utopianism and nostalgia alike are ways of abandoning discernment.
