The truth is that we are all sinners; nobody’s record is clean and indeed it is only fair to say that much of the very texture of the law invites us to sin, for it so often holds out to us, as though they were objective standards, terms like “reasonable care,” “due notice,” “reasonable restraint,” which are no more than signals that the dispute is to be decided with moderation and without disregard of any of the interests at stake.
