H.L.A. Hart makes a distinction between primary and secondary rules. I am unsure as to what to make of this. Right or wrong, this is what I have come up with:
Primary rules are the essential foundational element of secondary rules. In a sense, they are the social, academic, and philosophical norms that inform the foundation of secondary rules. Put another way, secondary rules are those norms in an institutionalized form.
Another way I thought of it was to to consider the primary rules to be the necessary conditions to establish the secondary rules. Conversely, the secondary rules are sufficient to prove the existence of the primary rules.
I could be completely off base here – any thoughts?
