Maurice Maeterlinck said this quote

We are not wrong, perhaps, to be heedful of justice in the midst of a universe that heeds not at all; as the bee is not wrong to make honey in a world that itself can make none. But we are wrong to desire an external justice, since we know that it does not exist. Let that which is in us suffice. All is for ever being weighed and judged in our soul. It is we who shall judge ourselves; or rather, our happiness is our judge.
