"The appeal to permission as the source of authority involves no particular moral vision or understanding. It gives no value to permission. It simply recognizes that secular moral authority is the authority of permission. This appeal is a minimal condition in relying on what it is to resolve issues among moral strangers with moral authority; consent. It establishes a secularly acknowledgeable authority for its conclusions: agreement. By appealing to ethics as a means for peaceably negotiating moral disputes, one discloses as a necessary and sufficient condition…for a general secular ethics the requirement to respect the freedom of the participants in a moral controversy…as a basis for common moral authority."
