|Rules, philosophy: rules are restrictions of a domain of possibilities for subjects, communities or functionaries, or generally for acting individuals or groups. Rules may be implicit or explicit, and may be implemented by ordinance or by jointly developing equally authorized participants, e.g. in a discourse. In another sense, rules can be understood as actual regularities that can be discovered by observation. These rules can be discovered not only in action, but also in the nature of objects such as linguistic structures. See also norms, values, rule following, private language, language rules, discourse, ethics, morality, cognitivism, intuitionism, society, practice.|

Laws / Rules / Logic / Wessel: Law = tautologies with operators.
Rules: sentences about formulas (the formulas are even not present as formulas but as quotations) = equivalences. "Equivalence" is not an operator.
