It is often argued that the rule of law is only instrumentally morally valuable, valuable when and to the extent that a legal system is used to purse morally valuable ends.

There is in practice a deeper connection between ruling by law and the pursuit of moral ends than advocates of the standard view recognize. The next part of this paper outlines Lon Fuller’s conception of the rule of law and his explanation of its moral value. The third..
